Sort functionality in Data Grid

Hi Gurus,
I am new to this DataGrid control.I want to establish the sort functionality when clicking on the headercolumns as in matrices.
(ie.When double clicking the header column , sort the data in ascending or descending order of that column) like in system form matrices.
How ever this is not possible when I tried with grid control.
The problem I am facing is that I cannot get the column headers of the grid programmatically.(in duble click event or itempressed event)
Anybody did this one previously? Also how
we can change the column order of the grid using screen painter?
The columns that actually come visible in the grid are actually columns of the linked datatable object.
In the designer ,there is no "swap" button for column re-ordering.
Only one way I know is changing the query associated with datatable.
This is a crucial thing ,since client may ask for re-ordering of columns frequently.
Can anybody help?
Regards,
Deepesh

Hi Deepesh,
1. This functionality is not available with the SDK. Thus it's not possible to change it on the fly. Your only option is to change the query associated with datatable (as you mentioned). You may set up a user preference table, that the user can configure with its preference. That's the best you can do.
2. To swap the columns in screen painter you must use SBO 2005 (it's not available on previous release). What you must do is, click on the one column you want to swap and the other you want to swap and click on the swap button (on the left bottom of the page in the columns tab)

How does the SORT function in ALV grid work?

Hi,
I have a report for which the o/p is displayed in ALV grid format.There is one column in the O/p strcuture which is "No of days".Based on certain conditions,i need to display the value for some of the days as Negative e.g. " - 45".Becasuse of this,I have declared the field for the "No of days" of the type "CHAR".
Now when i sort(using ALV grid SORT function) the list on basis of this column,it doesnt give me the correct o/p.
CAN anyone tell me how do i handle this?I want the list to be sorted correctly on basis of the "No of days" column.
Thanks!

Sort Direction in Data Grid

Hi
i want to know if the clicked column is sorted ASC or DESC,
While debugging step by step, i found a property in dataGrid whis is "sortDirection"
but this property is not accessible like this "dataGrid.sortDirection"
is there any method to access this property.
thank you

Hi, for using that kind of property you have to use 'mx_internal'.
I am putting the code here which can explore you mutch better.
<?xml version="1.0"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml">

Advanced Data Grid Sorting / Grouping Collection

Ok, basically here's the issue..
I have an advanced data grid with a tree view. It goes two
levels deep
so:
Report Type
|-------------------- Company
|--------------------------------------- Report 1
|--------------------------------------- Report 2
|--------------------------------------- Report 3
|-------------------- Company 2
|--------------------------------------- Report 1
|--------------------------------------- Report 2
|--------------------------------------- Report 3
Report Type 2
|-------------------- Company
|--------------------------------------- Report 1
|--------------------------------------- Report 2
|--------------------------------------- Report 3
|-------------------- Company 2
|--------------------------------------- Report 1
|--------------------------------------- Report 2
|--------------------------------------- Report 3
etc..
Report and Company are Nodes (folders) and are being sorted
alphabetically by default.
The individual reports (Report 1,2,3, etc..) are not being
sorted in any way that I can figure out. I need to sort them by
date, but no matter what I've tried I can't get it to work.
I tried a SortCompareFunction on the advancedDataGridColumn
that displays each report, and it works *IF* I click the header...
but if I dispatch the header_release event via AS3, nothing
happens.
I even set up a test:
dg.addEventListener(AdvancedDataGridEvent.HEADER_RELEASE,heard);
dg.dispatchEvent(
new AdvancedDataGridEvent
AdvancedDataGridEvent.HEADER_RELEASE,
false,
true,
0, // The zero-based index of the column to sort in the
DataGrid object's columns array.
null,
0,
null,
null,
0
function heard(e:Event) {
trace("I HEAR IT!");
trace(e.type);
I set that up on a button so I can dispatch the event with a
click. Every time I click the button, the header release event
listener goes off, but the actual advanceddatagrid remains
unchanged until I actually click on it's header..
Any help would be *GREATLY* appreciated... I've been stuck on
this problem for two days now :(

Custom sorting in data grid

Sorting entire records
Problem:
Assume you have an array of 20 items (master array), and
first 5 items are pulled into another array (paged array),
Which is the dataprovider for the datagrid. And the datagrid
has 10 columns.
When the user sorts on the datagrid, sorting should happen on
the 20 records, and
Not on the 5 records.
What i tried:
Clicking on a datagrid column header will sort only the data
provider of the datagrid. i.e., the
5 records. In order to sort all 20 records, sorting should
take place on the master array,
and not on the paged array. Sorting on 20 items seems to be
impossible.
The only logic we could think of was that, on the
headerRelease of datagrid, capture the
column header clicked(not sure if you can capture it or not).
And write custom function
for sorting based on that column. Since there are 10 columns,
the number of functions
or number of blocks of code to be written will Be 10. So did
not feel to be feasible and optimal solution.
Please advice.

Hello chhavs,
If you listen to the DataGrid's headerRelease event, the event has a property columnIndex to let you know which column the user wanted to sort. So you don't need 10 functions, just one with a switch statement, which is reasonable.
private function handleHeaderRelease(event:DataGridEvent):void
var sort:Sort = new Sort();
var field:SortField;
switch (event.columnIndex)
case 0:
field = new SortField("fieldA");
break;
case 1:
field = new SortField("fieldB");
break;
case ...
sort.fields = [field];
masterRecords.sort = sort;
masterRecords.refresh();
Thanks,

Sort on views in data grid (ORA-00904)

Can anyone else confirm that this happens, or has been highlighted previously:
1. Connect to any schema containing views
2. Expand the views tree
3. Click on any view
4. Click on the data tab to display the data grid
5. Click the sort button
6. Select any column (must not exist in view selected later)
7. Click "Apply Sort"
8. Now click on any other view that does not contain a column of the same name as the one chosen as the sort column previously.
I receive an ORA-00904 error. The only way I can clear this is to close down the data grid tab item, and re-open it.
Cheers

Yes.
Login as a DBA.
Go to Other Users - SYS - Views - More - Filter - %% - OK
Click on DBA_USERS - DATA - Sort - USERNAME - Apply Sort
Click on DBA_USTATS
--> ORA-00904 "USERNAME". invalid identifier.
Notice that the columns in the data view have not changed.
Close the tab and click on DBA_USTATS fixes the problem (no data anyway).
Click on freeze view (the push pin) and click on DBA_USTATS fixes the problem.
These are two easy workarounds, but it is confusing the first time you encounter it.

Adding a button in an Advanced Data Grid that calls a AS function

I'm having a bit of trouble with this... maybe I'm missing something elementary.
I have a data grid that populates. I'd like to make the first column that currently displays the an ID display a button that executes a function that acts on the passed ID.
I can get the button to display, but when I click it, I get an error:
ReferenceError: Error #1069: Property userlistDeleteUserFunc not found on Main and there is no default value.
at userGrid/__lblData_click()[C:\Users\Mike\\src\userGrid.mxml:7]
So the grid looks like this:
Main.mxml:
<script tags...>
private function userlistDeleteUserFunc(id:Number):void{
Alert.show(id.toString());
</script tags>
<mx:AdvancedDataGrid x="10" y="12" id="userlistgrid" width="808" height="348" dataProvider="{userlistdata}" selectionMode="multipleCells" editable="true" enabled="true" sortableColumns="true">

</mx:columns>
<mx:rendererProviders>

Please help me !!!! I have been stuck up with this issue for the past two days and I need to atleast figure out if this is possible or not in the first place.

Data Grid Sort Within Portlet

I have a portal with a portlet that contains a search form and a data grid. I have set the sortable attribute on the column to true. The sort action gets the filter service and passes it to the DB control.
I cannot seem to get the sorting to work. The output from getSortFilterService().getDatabaseFilter(getGridName()).getOrderByClause() is always empty no matter which column I click.
Is there something special I have to do because of the portal/portlet?
Can someone give me a tip (or two). I realize this is a novice question but I am learning as I go and would appreciate any help.
Edited by markml at 09/20/2007 9:41 PM

I figured it was locking up the browser. I submitted a bug ticket several months ago concerning the same issue. If you have "enableviewstate" set to true on a datagrid and you are using the PT web controls, then the browser will lock up. It all depends on the number of rows and columns you have in the datagrid; unfortunately, I don't know the fatal number.
However, what causes it is how Plumtree manages the viewstate itself for a datagrid. In a nutshell, they have to remember the viewstate for each single item in the grid. And the algorithm they use is extremely slow. The browser's scripting engine basically locks up because of the length of time it takes.
Unless you absolutely need it, I would just turn off the viewstate. It disables some fancy features of the datagrid, but you can still build workarounds.
Hope this helps/clarifies things for you!

Data Grid Recommendation

We are looking to add data grid functionality to our Apex app and am looking for any suggestions. Ideally it should be able to sort, resize, re-arrange and hide/show columns as well as load data asynchronously using the results of an AJAX request. Being able to resize the entire grid would also be nice.
I have seen references to integrating ExtJS into Apex but also have seen comments that it is written for an older version. Does anyone know if this is still correct?
I have also been looking at stand-alone jQuery plugins but am not sure how much work will be involved integrating this with Apex. Does anyone have experience with this?
Any help, pointers, suggestions, gotchas, etc would be appreciated.
Thanks,
Mark

Below is all of the JavaScript code. I found that, because Apex does not follow the standard method for passing parameters (sounds more like something Microsoft would do) you have to override the method used to send the data to the server. Also, since there is no way to change the content-type response header from 'text/html' (as far as I can find) you must also parse the resulting JSON string. Both of these actions are performed within the getPromoData function.
I haven't done more than get the table to display with pagination working so there may be other issues I run into along the way. I shouild also note that we are using Apex 4.0 and I understand there have been improvements in AJAX processing in Apex 4.2, so that may change things (hopefully for the better).

Hi,
Try labelFunction property of the DataGridColumn.
labelFunction allow you to specify a function name, which will be
invoked when that data is rendered. You will get the Object (User
id your case) corresponding the row being rendered will be passed
as argument to the function. You can use the object and return the
value you want to be displayed.
Please find more details on labelFunction at the URL below
http://livedocs.adobe.com/flex/3/langref/mx/controls/dataGridClasses/DataGridColumn.html#l abelFunction
You can also try custom item renderer.
Hope this helps.

FillBy always fills in the same row in data grid view. How to make it fill in a new row for each click of the Fillby Button? VB 2010 EXPRESS?

Hi there,
I am a beginner in Visual Basic Express 2010. I have a Point of Sale program that uses DataGridView to display records from an external microsoft access
database using the fillby query.
It works, but it repopulates the same row each time, but i want to be able to display multiple records at the same time, a new row should be filled for
each click of the fillby button.
also I want to be able to delete any records if the customer suddenly decides to not buy an item after it has already been entered.
so actually 2 questions here:
1. how to populate a new row for each click of the fillby button
2. how to delete records from data grid view after an item has been entered
Thanks
Vishwas

Hello,
The FillBy method loads data according to what the results are from the SELECT statement, so if there is one row then you get one row in the DataGridView, have two rows then two rows show up.
Some examples
Form load populates our dataset with all data as it was defined with a plain SELECT statement. Button1 loads via a query I created after the fact to filter on a column, the next button adds a new row to the existing data. When adding a new row it is appended
to the current data displayed and the primary key is a negative value but the new key is shown after pressing the save button on the BindingNavigator or there are other ways to get the new key by manually adding the row to the backend table bypassing the Adapter.
The following article with code shows this but does not address adapters.
Conceptually speaking the code in the second code block shows how to get the new key
Public Class Form1
Private Sub StudentsBindingNavigatorSaveItem_Click(
sender As Object, e As EventArgs) Handles StudentsBindingNavigatorSaveItem.Click
Me.Validate()
Me.StudentsBindingSource.EndEdit()
Me.TableAdapterManager.UpdateAll(Me.MyDataSet)
End Sub
Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
'TODO: This line of code loads data into the 'MyDataSet.Students' table. You can move, or remove it, as needed.
Me.StudentsTableAdapter.Fill(Me.MyDataSet.Students)
End Sub
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
Me.StudentsTableAdapter.FillBy(Me.MyDataSet.Students, ComboBox1.Text)
End Sub
Private Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click
Me.MyDataSet.Students.AddStudentsRow("Jane", "Adams", "Female")
End Sub
End Class

Problem in Data Grid

Hi All,
Account calculations are not displaying on the data grid. But the values are being picked up with a smart view report.
I tried running a force calculate and a consolidate all, but that did not work.
Please suggest in this regards.
Thanks in advance....

I tried to use your algorithm to modify my code but i am not able to do that. For this example i am not using any httpservice i am using data services. I created a PHP file i just need to import it into data services planel and drag that services onto data grid it will automatically bring all the data into that data grid. Can you tell me what i need to modify to achive my goal. am using following code
protected function dataGrid_creationCompleteHandler(event:FlexEvent):void
getHorizontalCommentResult.token = horizontalCommentsService.getHorizontalComment();
<mx:DataGrid x="159" y="123" id="dataGrid" creationComplete="dataGrid_creationCompleteHandler(event)" dataProvider="{getHorizontalCommentResult.lastResult}" height="223" width="245">
<mx:columns>
<mx:DataGridColumn headerText="Comments" dataField="Comments"/>
</mx:columns>
PP file
<?php
class HorizontalCommentsService{
public function getHorizontalComment() {
$connection = mysqli_connect("localhost", "root", "root", "my_db", 8889) or die(mysqli_connect_error());
$sql = "SELECT * FROM photo_comments ORDER BY Image_ID DESC";
$result = mysqli_query($connection, $sql) or die('Query Failed: ' . mysql_error($connection));
$rows = array();
while($row = mysqli_fetch_object($result)) {
$rows[ ] = $row;
return $rows;
?>
