Hello,

I guess you are using EditCommandColumn as the last column in MasterTableView for editing. If so enabling/disabling can be done in the ItemDataBound event as shown below.

<Columns>
    <telerik:GridEditCommandColumn UniqueName="ActionColumn" EditText="Update" UpdateText="Save"
        CancelText="Cancel" HeaderText="Action">
    </telerik:GridEditCommandColumn>

Code:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
 {
     if (e.Item is GridDataItem)
     {
         GridDataItem item = (GridDataItem)e.Item;
         if (Convert.ToInt32(item["Amount"].Text) >10000)
         {
             (item["ActionColumn"].Controls[0] as LinkButton).Enabled = false;
         }
     }
 }

Hi nagendra,

You can disable/hide the expand/collapse button in the ItemDataBound event for the grid in the following way:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
    {
        if (e.Item is GridDataItem)
        {
            GridDataItem gridDataItem = e.Item as GridDataItem;
            GridColumn amountColumn = gridDataItem.OwnerTableView.GetColumnSafe("Amount");
            if (amountColumn != null && int.Parse(gridDataItem["CompanyName"].Text)<10000)
            {
                TableCell tc = gridDataItem[RadGrid1.MasterTableView.ExpandCollapseColumn];
                //tc.Enabled = false; uncomment if you wish just to disable the button
                tc.Controls[0].Visible=false;
            }
        }
    }

On the other question if you need to add certain logic when the ExpandCollapse command is executed you can handle this in the ItemCommand event for the grid.

protected void RadGrid1_ItemCommand(object sender, GridCommandEventArgs e)
   {
       if (e.CommandName == RadGrid.ExpandCollapseCommandName)
       {
        //insert custom logic here
       }
   }

Let me know how this works for you and if you have any other questions.
