Itemindex in a Collapse/Expand Grid

[Christian]

Dear Comunity,

I have the following problem.

I have a grid with 10 Items grouped in 2 a 5 items for example.

If all groups are expand I can access all items with the index of itself. If I collaps one group and try to access a item with its index I get a error because the grid has only 5 items, but the index of the item to access has the index 8. I think this isn't a problem but how can get the correct index for each item in grid if a group is expand/collaps.

To get the index of the item to edit I'm using the RowDblClick event of teh grid and get the eventArgs.get_itemIndexHierarchical();

 

 

Is there a better solution to get it and solve my problem.
Thanks in advace.

Hi Christian,

I am not sure what exactly is your requirement.  But to set the Grid row in edit mode on double clicking a row you may try the following code snippet. The below given code does not depend on whether the Grouped Grid is expanded or collapsed. But any ways you need to expand the Grouped row to get access to its child item.

ASPX:

  <ClientEvents OnRowDblClick="EditOnDoubleClick"  />

JS:

<script type="text/javascript">

    function EditOnDoubleClick(sender, eventArgs)
    {
      var masterTable = $find("<%= RadGrid1.ClientID %>").get_masterTableView();
      masterTable.editItem(masterTable.get_dataItems()[eventArgs.get_itemIndexHierarchical()].get_element());
    }

</script>

Thanks
Shinu.

Hi Shinu

thanks for the replay.

Unfortunaly not. Becase the eventArgs.get_itemIndexHierarchical() returns a value thats currently out of range if the groups arroung are collapsed.(Most of all the first or last item in the expand group with a colapsed group before and a group after the expand group with the edit item)

So if I used your example with a collapsed group before and a collapsed group after the edit group the eventArgs.get_itemIndexHierarchical() gives me a wrong value. If I try than to get the datatiem with this value the functon returns undefines. On the otherside if alle gropups are expand evertyhing works fine.

Any idea for this problem?

Thanks
Christian

Hi,

Could you try setting the GroupLoadMode property of the grid MasterTableView to Client and see if it makes any difference? In this case you might also set the AllowGroupExpandCollapse property in the grid ClientSettings to true.
If the issue persists, I suggest that you send us a runnable sample illustrating your scenario and the issue you are facing. Thus I could debug it in depth locally in order to find a resolution for you.

All the best,
