The requirement is simple. But...
I want to mark the checkboxes which exist as a template column in a grid on other button's click event.

Hello,

You can try out the following code to checkmark the checkbox in the TemplateColumn on clicking a button. The code shows how to checkmark the checkbox for the row in which the button is clicked.
aspx:
 <telerik:GridTemplateColumn UniqueName="TemplateColumn3"
    <ItemTemplate> 
        <asp:CheckBox ID="CheckBox1" runat="server" /> 
    </ItemTemplate>            
 </telerik:GridTemplateColumn> 

cs:
protected void RadGrid1_ItemCommand(object source, GridCommandEventArgs e) 
    { 
        if (e.CommandName == "Check") 
        { 
            GridDataItem item = (GridDataItem)e.Item; 
            CheckBox chk = (CheckBox)item.FindControl("CheckBox1"); 
            chk.Checked = true
        } 
    } 

Thanks
Princy.

What I understand from the code you provided that the button is also included in the same row. This is not what I require. There is another button, outside the grid which handles the checking of the checkboxes in a grid. There is some more logic which calculates the checkstate of checkboxes amd check/uncheck them accordingly.

And not to forget the checkboxes exist on the rows of the child grid. (I am using hierarchical grids)

Hi Omarr,

Try the following code snippet to achieve the desired scenario.

ASPX:
<DetailTables > 
   <telerik:GridTableView DataSourceID="SqlDataSource1"  Name="Detail"  runat="server" > 
     <Columns> 
        <telerik:GridTemplateColumn UniqueName="MyTempCol" > 
         <ItemTemplate> 
              <asp:CheckBox ID="CheckBox2" runat="server" /> 
         </ItemTemplate> 
        </telerik:GridTemplateColumn> 
     </Columns> 
   </telerik:GridTableView> 
 </DetailTables> 

CS:
protected void Button1_Click(object sender, EventArgs e) 
    { 
        foreach (GridItem item in RadGrid1.Items) 
        { 
            if (item.OwnerTableView.Name == "Detail") 
            { 
                GridDataItem childitem = (GridDataItem)item; 
                CheckBox chkbx2 = (CheckBox)childitem["MyTempCol"].FindControl("CheckBox2"); 
                chkbx2.Checked = !chkbx2.Checked; 
            } 
        } 
    } 


Regards
Shinu.
