Ordering datagrid rows by dragging rows

Hi all,
I have a normal dg which is pulling data from MySQL db and
i'm trying
to figure out the best way to allow users to drag the rows to
re-order
as per however they may want it..
This is what I thought buy some feedback would be great!
1. Add 'order' column to sql db
2. Set inital order for each row
3. sort by order desc when pulling db into dg
4. Create function to:
a. when a user drops a row into desired position make each
rows
order = each rows index
b. update mysql db when all changes are complete
I also thought, maybe remember oldOrder val, + 1 to each
order value
from point of insertion until order = oldOrder??
Obviously this method has issues when the # of rows grows..
so thats
why I would love some help with this! there must be a better
way :)
Thanks in advance!

When clicking on datagrid row it throws me exception - WPF C#

Whenever I try to double click my datagrid row to edit it, I throws me a few exceptions which doesn't say anything to me. Hovever if
I set the whole datagrid to IsReadOnly to true, I want have the problem, but I need the second and third columns editable.

Exceptions
Exception:Thrown: "'EditItem' is not allowed for this view."(System.InvalidOperationException)
Exception:Thrown: "The string was not recognized as a valid DateTime. There is an unknown word starting at index 0." (System.FormatException)

You need to set the ItemsSource property of the clientList DataGrid to a collection of DataClients objects that supports editing. HashSet<DataClients> does not for example but List<DataClients> and ObservableCollection<DataClients> does.
You could call the ToList() method on the collection that you set as the ItemsSource for the DataGrid to convert it to a List<DataClients>:
clientList.ItemsSource = yourCollection.ToList();
The "The string was not recognized as a valid DateTime" error message should be pretty self-explanatory. You are trying to convert a string which doesn't contain a valid date or time value to a DateTime value somewhere, perhaps in the 'myTemplate'.
There is nothing in the DataClients class that you have posted that will cause this exception to be thrown so it is impossible for anyone to tell.
But please only ask one question per thread and then start a new thread if you have a new question.
Please also remember to mark helpful posts as answer to close your threads.

How to preset the order of rows in the outer query of a correlated query ?

Good morning,
I have the following simple query:
select empno,
       ename,
       sal,
       sum(case
             when rn = 1 then sal
             else -sal
           end) over (order by sal, empno) as running_diff
   from (
         select empno,
                ename,
                sal,
                row_number() over (order by sal, empno) as rn
           from emp
          where deptno = 10
         );That calculates a running difference and uses "row_number() over (...)" which is an Oracle specific feature to do so. It yields the following result (which we will consider correct):
     EMPNO ENAME             SAL RUNNING_DIFF
      7934 MILLER           1300         1300
      7782 CLARK            2450        -1150
      7839 KING             5000        -6150I wanted to come up with a solution that was not Oracle specific different solution. I tried the following code:
(EDIT: after additional thought, that code is totally different in meaning and will never come close, to the above result. Consider it wrong and ignore this attempt altogether.)
select a.empno,
       a.ename,
       a.sal,
       (select case
                 when a.empno = min(b.empno) then sum(b.sal)
                 else sum(-b.sal)
               end
          from emp b
         where b.empno <= a.empno
           and b.deptno = a.deptno) as running_diff
from emp a
where a.deptno = 10;but the result is
     EMPNO ENAME             SAL RUNNING_DIFF
      7782 CLARK            2450         2450
      7839 KING             5000        -7450
      7934 MILLER           1300        -8750which is a long way from the original result. I've tried everything I could think of to order the rows before the running difference is calculated but, have been unsuccessful.
Is there a way to change this second query --(without using Oracle specific features)-- without using windowing features that would yield the same result as the first query ?
Rephrase of the above question:
Is there a way, using plain vanilla SQL (that is aggregate functions and set operations such as joins and unions) to create a query that yields the same result as the first one ?
Also, this is not for production code. This is simply an exercise in set manipulation that I'd like to see a solution for.
Thank you for your help,
John.

Hi, John,
One way to get a running total (which is basically what you want) is to do a self-join. Join each row (let's call it the current row, or c) to itself and everything that came before it (let's call this the previous row, or p), and do a regular aggregate SUM, like this:
WITH     got_base_sal     AS
     SELECT       deptno
     ,       2 * MIN (sal)     AS base_sal
     FROM       scott.emp
     GROUP BY deptno
SELECT       c.deptno
,       c.empno
,       c.ename
,       c.sal
,       b.base_sal - SUM (p.sal)     AS running_diff
FROM       scott.emp     c
JOIN       scott.emp     p     ON     c.deptno     = p.deptno
                    AND     (     c.sal     > p.sal
                         OR     (     c.sal     = p.sal
                              AND     c.empno     >= p.empno
JOIN       got_base_sal     b     ON     c.deptno     = b.deptno
WHERE       c.deptno     IN (10)
GROUP BY c.deptno
,       c.empno
,       c.ename
,       c.sal
,       b.base_sal
ORDER BY c.deptno
,       running_diff     DESC
;Output:
    DEPTNO      EMPNO ENAME             SAL RUNNING_DIFF
        10       7934 MILLER           1300         1300
        10       7782 CLARK            2450        -1150
        10       7839 KING             5000        -6150I said you basically want a runninng total. There are two differences between a running total and your requirements
(1) You want to have a total of the negative of what's in the table. That's trivial: use a minus sign.
(2) You want the first item to count as positive instead of negative. That's not so trivial. The query above counts all sals as negative, but adds an offset so that it appears as if the first item had been counted as positive, not negative.
You didn't say what you want to do in case of a tie (two or more rows having the same sal). The query above uses empno as a tie-breaker, so that all sals are calculated as if they were distinct. This is similar to what analytic functions do when the windowing is based on rows. If you want something similar to windowing by range, that might actually be simpler.
The query above calculates a separate running_diff for each deptno, similar to "PARTITION BY deptno" in analytic functions. You happen to be interested in only one deptno right now, but you can change the main query's WHERE clause, or omit it, and the query will still work. If you don't want this feature (analagoud to not having any PARTITION BY), it's easy to modify the query.
You could also get these results using a recursive WITH clause. That meets the criteria of avoiding analytic functions and Oracle-specific features, but not the one about using only plain, simple SQL features.

Ordering of rows are showing difference when migration db from 9.2.0.8.0-32bits(windows 3) to 10.2.0.5.0 - 64bit(windows 8)?

Dears,
After migration(via export/import), we are facing ordering of rows are mis-match in these two databases.
the following same query I am running on the these two databases. but different output. output are below.

where can we look into for this issue? actually we need rows will be the same ordering as it was in 9i.
we are facing this problem in lot of queries, this is a sample one.
Regards
Halim

Hi Jgarry,
why do you need a particular physical order?
Actually i don't know the .net application behave or code yet . but after migration, I am facing this issue.
one more thing we changed the server machine so Is there any registry parameter (in windows) related to this. Have you any idea.
the application is running since 8 years and I think nobody can rely on implicit data distribution arising from how the data is entered to develop a application.
Hi Hoek,
According to Oracle White Paper(page 17), If I change below parameter. Is there any hope to get same order.
"After you upgrade to Oracle Database 10g, if you
wanted to revert back to 9.2 optimizer behavior you can set
OPTIMIZER_FEATURES_ENABLE = 9.2.0 "

Order of rows retrieved from collection

hi -- If I do not specify an ORDER BY clause when selecting rows from a collection, is
there any pre-defined order in which they'll be returned? (Eg perhaps in the order each
row is added to the collection...)
I ask because I've been using a particular collection for ages, but forgot to specify
an order when querying from it. Just today it returned the rows in a different order
than it has in the past -- only once -- and then they were returned as before.
The order I want -- and have been getting -- is the order in which they're added to the collection.
Will the 'no query transformation' hint accomplish this, or do I need a member that specifies the order?
Thanks,
C

How to display data in ComboBox when click on DataGrid Row.

Hi!
     I am new to Adobe Flex. I am building one Project that was related to Comapny and Customer. First I created Company Master. Then I create Customer Master successfully and My Backkend is SQLite Database.
     My Problem is I have two files one is CustomerMaster and second one is CustomerForm.
     In CustomerMaster I have a datagrid in that data was displaying thru Array Collection. When ever we doublick on datagrid row it's displayed a CompanyForm. CompanyForm contains TextFiled and ComboBox. TextFiled populating data but Combobox doesnot. It display always prompt message.
      Please help.
Thanks,
Sree Kumar

Hi! Vibhuti Gosavi,
                      First of all thanks for your quick reply. Already I saw that link.
Actually, In CustomerForm successfully store the information into the database. While retrieving the data problem cames. Sample Code:
CustomerMaster:
private function createItem():void
                                        openTab(new Object());
                              public function openTab(customer:Object):void
                                        var children:Array = tn.getChildren();
                                        var length:int = children.length;
                                        for (var i:int = 0; i<length; i++)
                                                  if (children[i].customer.customerId == customer.customerId)
                                                            tn.selectedIndex = i;
                                                            return;
                                        var form:CustomerForm = new CustomerForm();
                                        tn.addChild(form);
                                        form.customer = customer;
                                        form.dao = dao;
                                        form.addEventListener(CustomerEvent.CREATE, customerChangeHandler),

Insert String array as label content in datagrid row through radio button C# wpf?

I have written some code for inserting label at runtime having its content set to a string array and then insert that label into a datagrid row . All of this will initiate when certain radiobuttons are checked. code is working perfectly fine. But i need
to improve this code as i am learning C#, wpf and datagrid. I know there can be a certain way to improve this code.
This code will be a nightmare when there are 50 radiobuttons.
can it be improve and how it can be? if u can explain that will be very kind of you

@Usamakhan1990,
Use usercontrol with label and checkbox is reasonable for a datagrid control if you don't want to have too much code for those radio buttons. So I agree with andy here with that usercontrol.
So is it required that your radiobutton should be outside the datagrid?
Anyway, I think you already know that you can bind data to columns yourself. So please check the following thread:
http://stackoverflow.com/questions/22922533/how-do-i-automagically-bind-a-string-array-to-a-wpf-datagrid
<DataGrid Name="_dataGrid" Grid.Row="0" AutoGenerateColumns="False">
<DataGrid.Columns>
<DataGridTextColumn Header="Column 1" Binding="{Binding [0]}"/>
<DataGridTextColumn Header="Column 2" Binding="{Binding [1]}"/>
</DataGrid.Columns>
</DataGrid>
Or define the columns from code, in case you have dynamic number of columns, for example :
string[][] array = fs.CSVToStringArray();
for (int i = 0; i < array[0].Length; i++)
var col = new DataGridTextColumn();
col.Header = "Column " + i;
col.Binding = new Binding(string.Format("[{0}]", i));
_dataGrid.Columns.Add(col);
this.ExternalData._dataGrid.ItemsSource = array;
And for Radio button part, please see here:
http://stackoverflow.com/questions/397556/how-to-bind-radiobuttons-to-an-enum

TIPS(64) : ORDERING 된 상위 "N" ROWS 만 RETRIEVE 하는 SQL문

제품 : SQL*PLUS
작성날짜 : 2002-12-20
ORDERING 된 상위 "N" ROWS 만 RETRIEVE 하는 SQL문
===============================================
PURPOSE
다음은 특정 Column 으로 Ordering 된 상위 "n" rows 만 Return 하기 위한
간단한 SQL 문을 소개한다.
Explanation
Example
SELECT *
FROM table A
WHERE n >= (SELECT COUNT(*)
FROM table B
WHERE B.column >= A.column)
ORDER BY column DESC;
예) Emp Table 에서 Salary 가 많은 상위 5명만 구하는 SQL 문
SQL> select empno,ename,sal
2 from emp A
3 where 5 >= (select count(*)
4 from emp B
5 where B.sal >= A.sal)
6 order by sal desc
7 /
EMPNO ENAME SAL
7839 KING 5000
7788 SCOTT 3000
7902 FORD 3000
7566 JONES 2975
7698 BLAKE 2850
5 rows selected.
->Oracle 8i 이상인 경우
다음과 같이 간단히 query 할수 있다.
1 select empno,ename,sal
2 from (select * from emp order by sal desc)
3* where rownum <= 5;
위의 예는 상위 "n" Rows 만 정확히 Return 한다. 그러나 중복된
Column Value 를 가진다면 다음의 예를 고려해 보아야 할 것이다.
SELECT *
FROM table A
WHERE n >= (SELECT COUNT(DISTINCT column)
FROM column B
WHERE B.column >= A.column)
ORDER BY column DESC;
예)
SQL> select empno,ename,sal
2 from emp A
3 where 5 >= (select count(distinct sal)
4 from emp B
5 where B.sal >= A.sal)
6 order by sal desc
7 /
EMPNO ENAME SAL
7839 KING 5000
7788 SCOTT 3000
7902 FORD 3000
7566 JONES 2975
7698 BLAKE 2850

How to add event listener to datagrid ROW

I need to know if it is possible to have the datagrid rows execute a state change.
For example: I have a datagrid populated with various items, when one row is selected I want it to change the state of a part of the canvas it is in.
How is this possible? I can not give the row an id so I would not be able to say "when row is selected change state" because there is no way to tell what row is selected.
Help please. Thanks.

Incorrect sort order of rows in Purchase Order based on Sales Order

Hello Experts.
I have this problem on SAP B1 8.81 PL 04:
I create a Purchase Order based on a Sales Order with 10 item rows, ticking the purchase order box in the logistic tab.
The sort order of rows is different between PO and SO.
I need the same order of SO on PO.
Is there something I can do or it's a problem of this patch?
I saw the Sap Note nr. 824822 but it's related to SAP B1 version 2004 A...
Regards
Silvia Reggiani
Edited by: Silvia Reggiani on Oct 11, 2011 12:26 PM

Hi,
Are you able to reproduce the issue in the DEMO Database on the 8.81 PL04?
Also, have you checked the issue in the latest patch of the 8.81?

Analytical function count(*) with order by Rows unbounded preceding

Hi
I have query about analytical function count(*) with order by (col) ROWS unbounded preceding.
If i removed order by rows unbouned preceding then it behaves some other way.
Can anybody tell me what is the impact of order by ROWS unbounded preceding with count(*) analytical function?
Please help me and thanks in advance.

Sweety,
CURRENT ROW is the default behaviour of the analytical function if no windowing clause is provided. So if you are giving ROWS UNBOUNDED PRECEDING, It basically means that you want to compute COUNT(*) from the beginning of the window to the current ROW. In other words, the use of ROWS UNBOUNDED PRECEDING is to implicitly indicate the end of the window is the current row
The beginning of the window of a result set will depend on how you have defined your partition by clause in the analytical function.
If you specify ROWS 2 preceding, then it will calculate COUNT(*) from 2 ROWS prior to the current row. It is a physical offset.

Displaying Datagrid Rows Based on User Login Id

Hey Everyone,
So the problem I am having is that I am making a product configurator and when a user logs in I want to display there previous creations in a data grid so they can select edit or reorder them....the problem I am having is for some reason I can't get the designs to show up based on specific users...here is the process i am currently using in Flex 4.5
I create 2 tables in the database (Users and Designs)
     the id for the design is based on the id of the user that created it
In flex I create 2 php services
     -One generated from the users table for creating a new user for the configurator
     -The other one is generated from the Design table and I use the getAllDesigns(); to display the designs in the data grid
All of the login info is validated through php files that are used by an httpservice call
So my idea was to run an if statement to display the designs for specific user, something like this (i know the syntax isn't right this is just to get my idea accross
Var designId = datagrid.row.id;
(allready have userId var)
if(userId != designId)
     row.visible = "false"
I have tried many different approaches but cant get anything to work
Any Ideas would be helpful
Thanks In advance

Your right, i was trying to wrap my head around that idea earlier but decided to go with this option to just see if i could get this to work then work on the server side filtering...
How would I do this in theory,
my thinking is that i query in my php file something like
SELECT * FROM DESIGNS WHERE DESIGNS.ID = USERS.ID;
then take the filtered data and pass it to a xml document
then in flex create an array list out of the xml to insert into the datagrid?
or do you have a better idea?
also will that information even be able to be editable because i am parsing the data through the xml?
Thanks for any input

However, there is a lot of space between the rows making this
rather unattractive. Any thoughts or ideas?
<mx:DataGrid x="10" y="10" borderStyle="none"
sortableColumns="false" selectable="false" showHeaders="false"
fontSize="12" color="#000000" fontWeight="normal" width="392"
height="207">
<mx:dataProvider>
<mx:Object Label="Manufacturer" Value="General
Mills"/>
<mx:Object Label="Category" Value="Cereal breakfast
foods"/>
<mx:Object Label="Description" Value="Toasted whole grain
oat cereal with kid-friendly ring shape"/> 
<mx:Object Label="Quantity" Value="425 g Box"/>
</mx:dataProvider>
<mx:columns>
<mx:DataGridColumn dataField="Label" headerText=""
textAlign="left" width="115"/>
<mx:DataGridColumn dataField="Value" headerText=""
textAlign="left" wordWrap="true"/>
</mx:columns>
</mx:DataGrid>

Accessing Datagrid row data from within an itemRenderer

I would like to know how I can access another row's data from within an itemRenderer. I need to do some formatting of my cells based on other row data. Here's what I mean... I have a datagrid and in row 0 col 2's itemRenderer I would like to access row 1 col 1's data in order to do a comparison so I can determine how to format row 0 col 2's data and so on. Is there a way from within the item renderer to reach into another row and access the data? I can't seem to find a clear answer so I thought I'd go to the pro's.
Thanks!!

You can use this code to get to the dataProvider of the grid.
var o:Object = this.parent.parent;
var dp:Object = o.dataProvider;

Purchase order document row is not change (document stutas is OPEN)

Hi all,
I am created one purchase order that are not any base or targeted document ,not any approval procedure and purchase order document status is steel open . Then how I a cannot change the document row.
thanks
arabinda pal

Hi Deepa,
I think if you want to restrict the further editing of a particular row, then you just need to follow the simple procedure.
1. create the purchase order with your desired items & vendor & add this document
2. Now reopen it & goto that row which you want to restrict. Right click on that row & select "Close Row".
3. Select yes to confirmation message.
4.Now update the document.
Now you an check it out, in that document you will not be able to edit that row contents.
I hope this solves your issue.
Regards.
