Question

I have one dropdown box inside the item template. As per of my requirement I need to update the tooltip field of drop down in aspx.cs page.

I use the following code:

<asp:TemplateField HeaderStyle-CssClass="grid-label-small" HeaderText="*State">
  <ItemTemplate>
    <asp:DropDownList ID="ddlDefState" Width="110px" runat="server" ToolTip="Select State">
    </asp:DropDownList>
  </ItemTemplate>
  <HeaderStyle CssClass="grid-label-small" />
</asp:TemplateField>`.

Thank you…

Hi you can find the Item template control using this assuming you are binding in RowDataBound event. Add OnRowDataBound event to GridView like this,

<asp:GridView runat="server"   OnRowDataBound="grd_RowDataBound"  ></asp:GridView>

protected void grd_RowDataBound(object sender, GridViewRowEventArgs e)
{
   if (e.Row.RowType == DataControlRowType.DataRow)
   {
     DropDownList dropDown;

     dropDown= e.Row.FindControl("ddlDefState") as DropDownList;

      if (dropDown!= null)
        // Write your code here            
    }
}

Optionally, you may also be able to bind to tooltip from asp:GridView markup in this way,

<asp:TemplateField HeaderStyle-CssClass="grid-label-small" HeaderText="*State">
  <ItemTemplate>
  <asp:DropDownList ID="ddlDefState" Width="110px" runat="server" 
    ToolTip="<%# Bind("Your Property Name") %>">
</asp:DropDownList>
</ItemTemplate>
  <HeaderStyle CssClass="grid-label-small" />
</asp:TemplateField>

Hope this helps. Thanks
