tooltip for Radgrid hierarchy image Button...

[Srinivasa Gokidi]

Hi,

I am using a Radgrid Hierarchy with girdimagebuttons. And I am ptoviding the tooltip to the buttons using the below code and it works fine.

<telerik:GridButtonColumn UniqueName="EditCMNbr" CommandName="EditCM" ImageUrl="~/Images/edit-icon-v5.gif"
   ButtonType="ImageButton" HeaderStyle-Width="3%" ItemStyle-Width="3%">
</telerik:GridButtonColumn>
<telerik:GridButtonColumn UniqueName="AddSMNbr" CommandName="AddSM" ImageUrl="~/Images/add-icon.png"
   ButtonType="ImageButton" HeaderStyle-Width="3%" ItemStyle-Width="3%">
</telerik:GridButtonColumn>

protected void RGCMnbr_ItemDataBound(object sender, GridItemEventArgs e)
{
    if (e.Item is GridDataItem)
    {
        GridDataItem dataItem = (GridDataItem)e.Item;
        ImageButton btnEditCM = (ImageButton)dataItem["EditCMNbr"].Controls[0];
        btnEditCM.ToolTip = "Edit CM";

        ImageButton btnAddSM = (ImageButton)dataItem["AddSMNbr"].Controls[0];
        btnAddSM.ToolTip = "Add SM";
    }

}

The Issue is When i click the Expandcolumn in my radgrid Hierarchy I am getting error like cell bound column is not find. Please see the Images. Please let me know how to achieve this.

Thanks.

Hello Srinivasa,

You are getting this error because you did not distinguish grid rows in hierarchy on ItemDataBound event. You need to identify the table to which the current row belongs like below.

ASPX:

<telerik:RadGrid . . . . .>
     <MasterTableView Name="Master" . . . .>
          . . . . . .

C#:

protected void RGCMnbr_ItemDataBound(object sender, GridItemEventArgs e)
   {
      if (e.Item is GridDataItem && e.Item.OwnerTableView.Name == "Master")
       {
           GridDataItem dataItem = (GridDataItem)e.Item;
           ImageButton btnEditCM = (ImageButton)dataItem["EditCMNbr"].Controls[0];
           btnEditCM.ToolTip = "Edit CM";
           ImageButton btnAddSM = (ImageButton)dataItem["AddSMNbr"].Controls[0];
           btnAddSM.ToolTip = "Add SM";
       }
   }

Please go through the following documentation for information on this:
Distinguish grid rows in hierarchy on ItemCreated/ItemDataBound
