Hi,

Greetings,

I am working on displaying the data in self hierarchy using Rad grid. I have taken the code given by the Rad grid demo page.
When iam displaying the data in Web application, i am getting the data in self hierarchy and it is working perfectly.

Then i am trying to display the same grid in visual web part (share point 2010) and after deploying it in the share point, when iam loading the web part, iam getting an message "Stop running the script, if you are trying to run the script your browser will be non -responsive" and then my Page_Prerender event is not firing. In that event, when there are no nested items, hiding the expand collapse image is not working.

I am working on Windows 7 machine having Sharepoint foundation. I am deploying my visual web parts in that share point foundation.

Could any one please let me know if you have a work a round for this.

Thanks
Murthy

Hi telerik Team,

I am using Rad Grid in my application. I am displaying data in self hierarchy in the Rad Grid.

I am displaying rad Grid with self hierarchy in a visual web part in a model dialog in Share point 2010.

Could any one please let me know, how to post back the selected row values to the parent form client side.

As i am using self hierarchy grid, i need to find the selected row information. The selected row can be there in any nested table.

please let me know what is the correct event to use for this work around.

Thanks in advance.

Thanks,
Murthy

Hello Murthy,

You could try attaching the client side event handler to the RadGrid1.ClientSettings.ClientEvents.OnRowSelected event:
RadGrid1.ClientSettings.ClientEvents.OnRowSelected = "OnRowSelected";

Into OnRowSelected event handler function, you could get the itemIndexHierarchical of the current selected row and remove the string after the last ":" symbol. In this way you will receive the parent item's itemIndexHierarchical. For example if you only one child level:
<script type="text/javascript">
 function OnRowSelected(sender, eventArgs)
 {
    var itemIndexHierarchical = eventArgs.get_itemIndexHierarchical();
    var parentItemIndexHierarchical = itemIndexHierarchical.substring(0,itemIndexHierarchical.indexOf(":"));
    var parentItem = sender.get_masterTableView().get_dataItems()[parentItemIndexHierarchical];  
 }
 </script>

Please give it try and let me know if it helps you.

Kind regards,

I am having a result set with the structure of
Level1                         Level2           Level3               CalcField
---------------------------------------------------------------------------
Akron                Cleveland OH         2007-QTR 1     206172.0000
Akron                Cleveland OH         2007-QTR 2     225291.0000
Akron                Cleveland OH         2007-QTR 3     210866.0000
Allen                  Dallas-Fort Worth  TX 2009-QTR 1 27241.0000

Allen                  Dallas-Fort Worth  TX 2009-QTR 3 100539.0000

And the output of the grid should be,

               TX 2009-QTR 1   27241.0000
               TX 2009-QTR 2   62850.0000

I have gone through the samples with ParentKeyname and DataKeyNames Concept.But i dont have the parentid concept in my query.

Hello Brinda,

If you do not have Parent->Child relation you could not use the Self-Reference RadGrid. However in your case you could try using the grouping and group by Level1 and Level2. For example:
<GroupByExpressions>
   <telerik:GridGroupByExpression>
      <GroupByFields>
         <telerik:GridGroupByField FieldName="Level1" />
      </GroupByFields>
      <SelectFields>
         <telerik:GridGroupByField FieldName="Level1" />
      </SelectFields>
   </telerik:GridGroupByExpression>
   <telerik:GridGroupByExpression>
      <GroupByFields>
         <telerik:GridGroupByField FieldName="Level2" />
      </GroupByFields>
      <SelectFields>
         <telerik:GridGroupByField FieldName="Level2" />
      </SelectFields>
   </telerik:GridGroupByExpression>
</GroupByExpressions>

Additionally I am sending you a simple example which demonstrates the RadGrid grouping. Please check it out and let me know if it helps you.

Kind regards,
