ExpandCollapseColumn positioning

[Chris]

I've got a hierarchical grid with one DetailTable.  The RadGrid is auto-generating an ExpandCollapseColumn on the left, and I'd really like to either move it so it's the rightmost column, or prevent it from being generated so I can just declare my own.  Is there any way to do either of these?

Hello Chris,

The best approach would be to hide the autogenerated expand column and create your custom column:

protected void RadGrid1_ColumnCreated(object sender, GridColumnCreatedEventArgs e)
    {
        if (e.Column.UniqueName == "ExpandColumn")
        {
            e.Column.Display = false;
        }
    }

aspx:

  <telerik:GridExpandColumn ButtonType="ImageButton" CollapseImageUrl="../Image1.bmp" ExpandImageUrl="../Image2.bmp">
  </telerik:GridExpandColumn>

Thanks
Princy.

Dear Princy, thanks for the help you provided. it helped me also with the same problem. there is one more issue i am facing, the approach you explain hides the expandcollapasecolumn for the mastertable but if i try to hide the expandcollapasecolumn for the detail table it just not work and i still get the auto genrated expandcollapasecolumn.

Can you please help me out on this, any example will be a great help.

Thanks

Hello Nitesh,

The above code could be used to hide all the expand columns in your grid regardless of which ownertableview it actually belongs to. I tried the same and it worked as expected. I also tried the following code to hide the expand column for a specific gridtableview using its name property. Can you check if this triggers fine for you?

aspx:

<telerik:RadGrid ID="RadGrid1" runat="server" DataSourceID="Sqldatasource1">
     <MasterTableView Name="Master" HierarchyDefaultExpanded="true" DataSourceID="Sqldatasource1">
           <DetailTables>
                  <telerik:GridTableView HierarchyDefaultExpanded="true"  DataSourceID="Sqldatasource2" Name="Detail" runat="server">

c#:

protected void RadGrid1_ColumnCreated(object sender, GridColumnCreatedEventArgs e)
    {
        if (e.Column.Owner.Name == "Detail"  && e.Column.UniqueName == "ExpandColumn")
        {
            e.Column.Display = false;
        }
    }

Dear Princy,

Thanks Allot it worked :). now i am facing a very strange problem with the images of expandCollapseColumn. as you explained i added the  telerik:GridExpandColumn  with the imageurl pointing to my images, my grid HierarchyLoadMode is Set to Client, now what is happening once i click on the Expand Plus image the grid expand and somehow the path to the images are lost it starts showing that X sign when we have the missing image, the interesting part is if the HierarchyLoadMode is set to ServerBind the images path are always intact.

I hope i am able to explain my problem,

Thanks & Regards
