I want to share how to get a confirmation popup when deleting a record from a ASP.NET 3.5 Gridview.
Here’s how you can do it.
First create the javascript function and place it in your head section.
<head runat=”server”>
<title>GridView Data Manipulation</title>
<script type=”text/javascript” language=”javascript”>
function ConfirmOnDelete()
{
return confirm(“Are you sure to delete ?”);
}
</script>
</head>
Then add a Template field in your gridview like shown below, look at the CommandName attribute, that’s important.
<asp:GridView ID=”TypesGridView” runat=”server” AllowSorting=”True”AutoGenerateColumns=”False” DataKeyNames=”Id” DataSourceID=”CustomerDS”><Columns><asp:BoundField DataField=”CustomerID” HeaderText=”ID” ReadOnly=”true” /><asp:BoundField DataField=”CompanyName” HeaderText=”Company”/><asp:BoundField DataField=”ContactName” HeaderText=”Name”/><asp:BoundField DataField=”ContactTitle” HeaderText=”Title” /><asp:BoundField DataField=”Address” HeaderText=”Address”/><asp:BoundField DataField=”Country” HeaderText=”Country”/><asp:TemplateField><ItemTemplate><asp:LinkButton
ID=”LinkDelete” runat=”server” CommandName=”delete” OnClientClick=”return ConfirmDelete();”>Delete</asp:LinkButton>
</ItemTemplate></asp:TemplateField></Columns></asp:GridView>
