Visible Row Count

I wish to have paged results(something like 10-20 rows out of
a few hundreds) in a data grid. When resizing the screen, the
datagrid changes size, and thus the number of row displayed
changes. I did not find the property or function which allows me to
bind unto in order to get the number of visible rows.
DataGrid.rowCount is 0 unless set, and it is not bindable. Any idea
how I can find that information?

Hi,
1) The rowCount is the right property. It is zero until the
app is finished laying out and sizing all components.
2) rowCount IS bindable; it just does not dispatch an update
event, so if for instance a Label's text property is bound to
DataGrid.rowCount, it will always read zero.
So what you really need to do is get the rowCount AFTER the
application's creationComplete event, and whenever the DataGrid
changes its size.
The following code uses the app's creationComplete event to
get the initial rowCount property and display it in a Label. I also
add an event handler for the DataGrid's render event, which is
fired whenever the DataGrid has to re-draw itself.
There may be an easier way to do it. Maybe someone else has a
more elegant solution. Hope this helps.

How to get visible row count in JTable ?

I have one table which is added to one scroll pane. For example my table have total 1000 rows, but at a time only 20 rows should be visible to the scroll pane. And I want to scroll the rows and show only 20 at a time.When user scrolls JTable then next time he can view only 1 to 21, then 2 to 22, and so on. I want to know how to get that number which represents the visible row( in this case it is 20).So kindly help me how to get visible row count. Any help regarding this will be appriciated.
Thanks and Regards,
Sheetal

how to get visible row count.First you need to get the viewport used by the scrollpane. Then you can use methods like getViewPosition() and getViewSize() to get information about the current postition of and size of the viewport.
Then you can use the table method getRowAtPoint(). to determine the first and last visible row which can then be used to calculate the visible row count.
When user scrolls JTable then next time he can view only 1 to 21, then 2 to 22, and so onThis is the default behaviour when a "block" scroll is done.
However when you click on the arrow button on the scrollbar it will only scroll a single row. You could override the getScrollableUnitIncrement() method to return the value from the getScrollableBlockIncrement() method.
However the user can still drag the scrollbar manually which would cause a problem. So you would also need to remove the MouseMotionListeners from the scrollbar to prevent this.

How to set visible row count dynamically

i need to place input field so that user enters value for visible row count in ALV WEBDYNPRO

Hi Prabhu,
As Suggested use set_visible_row_count. First count your table entries. based on count display records.
count = LINES( lt_n_contract ).
IF count > 5.
lt_table_settings->set_visible_row_count( value = 10 ).
ELSE.
lt_table_settings->set_visible_row_count( value = 3 ).
ENDIF.

Setting the Vissible Row count Dynamicaly

Hi,
I need to set the Vissible row count dynamically in Webdynpro Java, depending upon the number of rows in the internal table.

Hi Delphi,
This is Webdynpro ABAP Forum, Try to post in Webdynpro Java. I dont know WD Java.
Create one attribute of type i ex : COUNT TYPE I, and bind to visible row count property of table.
In code Describe table and get total no of records to one variable.
Finally use Set_attribute - Pass COUNT Value. Now Based on Count Value you get no of table rows.
Hope it Helps.
Cheers,
Kris.

Create a group based on row count

I am looking for a way of reducing the size of tables I am displaying in my monthly report, by counting some rows together, and naming them 'other'
I would like to always show all rows, where count of item is >= 50, but all rows where count of item < 50, total up and call 'other'. I will add an example image as soon as my account has been verified
I can hide rows using this in the visibility =iif(Count(Fields!Item.Value) >= 50, False, True)
I have duplicated the line, and added a filter to each (one for greater than 50, one for less than 50) but my totals are still counting all the data, and not just the filtered data.
Ideally, I would like to add a column using something like =iif(Count(Fields!Item.Value) >= 50, "Over50", "Under50"), or a group based on the same sort of idea, but I keep getting errors about using aggregates in columns.
Any suggestions?
Cheers

What you can do is to add derived column in query behind like this
SELECT other columns...,
CASE WHEN Cnt >= 50 THEN YourGroupingField ELSE 'Other' END AS GrpName
FROM
SELECT *,COUNT(1) OVER (PARTITION BY YourGroupingField) AS Cnt
FROM Table
)t
Then in your reports use =Fields!GrpName.Value as the Grouping column and you will get required output

How to group by a number of visible rows in drill down report

hi,
i have a drill down report with no detail row.
I need to control the number of rows shown on the page based on a variable that a user supplies, however it needs to be only visible rows.
if I add an outmost group based on an expression like this one:
=Ceiling(RowNumber(
"table1")/Parameters!recordsPerPage.Value)
it will count all rows - visible or not.
any help would be appreciated.
thanks
Inna

Hi Inna,
Based on my research, a drilldown report is a layout design that at first hides complexity and enables the user to toggle conditionally hidden report items to control how much detail data they want to see. Drilldown reports are used to change the report
layout interactively. So it wouldn’t affect the rows displayed in the outmost group. Though some rows are hidden when the report is initially run, it will still count them. This is by design.
Furthermore, if I understand correctly, you also expect the outmost group is a dynamic group depends on the drilldown action, right? As per my understanding, this function still cannot be achieved at this moment.
Thanks for your understanding.

Number of visible rows

hi,
I want to display all the records of the table without restriction. Normally If I have 1000 records then the number of visible rows will be equal to the length of the table and we get scroll option to see the other records. If I want to make the number of visible rows equal to number of records is it possible?
thanks,

Hi,
Assign the count of records to the 'No of rows' property of the table.

Row Count

What I would like to do is do row counts across 2 schemas with same tables and see if there are any differences in row counts and if there is any would like to generate an email and alert the user.
Is it possible?

Hello,
Yes it is possible, you need to
grant select on user2.table_name1 to user1; (you can grant select to all tables of user2 to user1 or otherway) and then write pls/sql procedure to send email using utl_smtp.

DataTable.Rows.Count property is occasionally wrong

I have a web service in C#.NET which calls a stored procedure using ADO.NET. The stored procedure is always returning 1 row, which is then loaded into a DataTable. The Rows.Count property of the DataTable is then examined.
When this web service is called repeatedly with numerous requests, it occasionally returns Rows.Count as 0 when it should be 1. I have debugged and examined it at runtime and found that there is indeed 1 row in the datatable, but that the Rows.Count property
is 0.
Is this a known bug?
I'm using .Net Framework 2.0
Note: This is an issue that occurs very rarely. My testing shows that it takes about 90 minutes to recreate it when you have 2 concurrent processes sending requests repeatedly at a rate of about 10 requests per second.

Are you sure that there aren't multiple threads access the DataTable?
Can you post a repro?

Dynamically set maximum row count in Interactive Report

Hi,
Has anyone worked out a way of dynamically setting (e.g. via select list) the maximum row count value for an Interactive Report, taking into account issues with order by when the report is filtered. I'm aware of solutions like this: http://www.talkapex.com/2010/10/apex-reports-no-limit-downloads.html but as far as I can tell this doesn't work when the report is filtered and the IR is rewritten in the background. Data sets then become unreliable because they are reordered.
Thanks,
Mike

Hi Mike,
You can do that with javascript
gReport.search('SEARCH',100)the 100 you can replace for any number you like.I have a report with filter,sorting and groups and it is gives no problem there.
any number means any number but not higher than the number you set at Maximum Rows Per Page.
You probably can mix the solution from Martin and the above code.

How to add the Row count(number of rows in table) in the table header?

Hi,
I'm having a table. This table is viewed when i click on a search button.
<b>On the table header it should dynamically display the number of rows in the table, i.e., the row count.</b>
How to do this? could any one explain me with the detailed procedure to achieve this.
Thanks & Regards,
Suresh

If you want to show a localized text in the table header, you should use the <b>Message Pool</b> to create a (parameterized) message "tableHeaderText" like "There are table entries".
Next, create a context attribute "tableHeaderText" of type "string" and bind the "text" property of the table header Caption UI element to this attribute.
Whenever the table data has changed (e.g. at the end of the supply function for the table's data source node), update the header text:
int numRows = wdContext.node<TableDataSourceNode>().size();
String text = wdComponentAPI.getTextAccessor().getText
IMessage<ComponentName>.TABLE_HEADER_TEXT,
new Object[] { String.valueOf(numRows) }
wdContext.currentContextElement().setTableHeaderText(text);
Maybe you want to provide a separate message for the case that there are no entries.
Alternatively, you can make the attribute calculated and return the header text in the attribute getter.

Unable to get the row count of supplier site for each supplier

Hi,
In the sourcing module, suppliers page is having an advanced table in which there is a field 'supplier' and another filed 'supplier sites' (supplier field is of type picklist).Now, how can i get the count of 'supplier sites' for each supplier???

Hi sumit,
Thanks for the reply, can u please help in writing the code to loop through the VO...
I was trying to get the first row and then finding the count of supplier sites, but in each iteration of for loop(for each row) i am getting the same count value for each and every row...
Code :
int j=vo.getrowcount();//count of no. of rows
for (int i=0;i<j;i++)
row=(xxVORowImpl)rowsetiterator.getRowAtRangeIndex(1);
int a=am.getSupplierSitesVO.getRowCount();//this is the view object in the pick list
oapagecontext.writeDiagnostics(this,"value of a is :"+a,1);
this code is giving row count of last row of supplier.
How to get the count for each and every row of supplier sites ?
Thanks.
