GridReport = BLL.BO.Reports.

Operations.GenerateReportColumns(ref GridReport);

break;
}

private void GridReport_NeedDataSource(object source, GridNeedDataSourceEventArgs e)

{
//do something

GridReport.DataSource = dt;}

void GridReport_PageIndexChanged(object source, GridPageChangedEventArgs e)

{

// DO SOMETHING, HERE THE BREAKPOINT NEVER HITS!
}

Thanks for your help!

Access GridTemplateColumn?

How do I access a GridTemplateColumn in the Grid row that was clicked?

With the getDataKeyValue() method I can get the value of GridBoundColumns after defining the columns using the ClientDataKeyNames property of the MasterTableView.

But how can I get the value of GridTemplateColumns?

Show filter options based on number of rows returned

Hi there.

Could someone please give me a pointer as to how to display the column filters only if the number of rows INITIALLY returned by a grid is greater than x?

I say "initially" for a reason. Let's say x above is 20. If the grid initially returns 30 rows the filters will appear. But if I filter the grid so that only 5 rows come back based on my filter expression then the grid needs to know this is 5 out of 30 rows so it still needs to show the filters. I.e. It's the 30 that is important here, not the 5.

I'm assuming I will use the onDataBound event. But I dont know how to get the number of rows returned. And I assume there is a "total" variable I can tap into that is the number of rows regardless of any filter applied?

Thanks in advance.

Chris

Performing Batch Update Using GridTemplateColumn

Hello,
I am attempting to implement batch updating using controls that are located within the EditItemTemplate of a GridTemplate Column. I am currently using a OnPreRender event to set all datagrid columns to edit mode. The idea is the user should then be able to select values in a radcombobox and check box located in a GridTemplate column for each entry in the grid. After the users has made their edits to multiple rows in the grid they should be able to hit a single button to process all updates. I am attempting to use an approach similar to what is described in this article however I have been having difficulties with my OnItemCommand event as I have been unable to retrieve the values the radcombo box and check box in my EditItemTemplate have been set to.
Below is what I am attempting to do currently. Also I would like to remove the "update" and "cancel" links from the EditItemTemplate rather then set the text of the link to nothing in a OnItemCreated event as I am doing currently. Thanks in advance for helping out a Telerik beginner.

GridView Height Problem in Differenet Browser

hi all,
I have rad grid in my page. The page is designed with Rad splitter and rad pane. I enabled paging for the grid. Now my requirement is that the grid should be 100% height so that my pager should always display at the bottom of the page. For this i tried the following options

Option 1: Set height property of the grid to 100%
This option perfectly worked in the IE 8. But this is not worked in the Firefox

Option 2: Created on css class for the grid and apply the css class. The following is the css class

        .grid
        {
            height:auto !important;
            height:100%;
            min-height:250px;
        }

But this not helped

Option 3: Created css class for the pager and applied. The following is the css class

        .pagerPosition
        {
            position:absolute;
            bottom:10px;
            text-align:right;
 
        }

This helps some what like the pager moved to the bottom but some spacing difference in different browser.

Can anyone helps to work around for the problem?

But If typed Upper case and low case charactors as exactly same as the data value then it filters data properly. I am really appreciated if someone can tell me how can I remove upper case filters and set Contains filter as default. Thank you.

RadGrid won't work in EditMode=InPlace

Hello,

I am trying to build a Radgrid based on this example:
http://demos.telerik.com/aspnet-ajax/grid/examples/dataediting/editondblclick/defaultcs.aspx

It works fine when I set EditMode to PopUp or EditForms, but when I try to set it to InPlace I get the following error after a double click on a row:

Specified argument was out of the range of valid values.
Parameter name: index

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

When I debug the page after a double click I can see the DataSource is correctly set in the NeedDataSource event, all rows are properly handled in the ItemCreated and ItemDataBound events the same way they are when I use an other EditMode. But after this I get the above error only in EditMode=InPlace.

Does anyone know what could be the problem?
