Hi,

Try this:

In your client code:

   <asp:TemplateField ItemStyle-HorizontalAlign="Center" HeaderText="Delete">
  <HeaderTemplate>Delete</HeaderTemplate>
     <ItemTemplate>
        <asp:ImageButton ID="Imgdelete" runat="server" 
        ImageUrl="~/admin/Images/Delete.gif" ToolTip="Delete product" 
        onclick="Imgdelete_Click" OnClientClick="return confirm('Delete this record?');"  />
     </ItemTemplate>
  <FooterTemplate></FooterTemplate>
</asp:TemplateField>

In your code behind:

   protected void Imgdelete_Click(object sender, ImageClickEventArgs e)
{
    GridViewRow row = (GridViewRow)Imgdelete.NamingContainer;
    string productName = row.Cells[0].Text;
    string quoteID  = txtquoteid.Text;
    
    //...Some code here...
    cmd = new SqlCommand("Delete from Quote_pro_details where p_name='" + 
          productName + "' and Quote_ID='" + quoteID + "'", con);
    //... Some Code here...
     
}

Hope this could help:
