Gridview

I have gridview in a page with button.

i want to execute a query when user click button and then that row should be deleted.

I was trying a demo but it is not working.

<asp:GridView ID="GridView1" runat="server"
onselectedindexchanged="GridView1_SelectedIndexChanged">
<Columns>
<asp:TemplateField HeaderText="Delete" HeaderStyle-CssClass="title_bg" ItemStyle-HorizontalAlign="Center">
<asp:LinkButton ID="lkDelte" runat="server" OnClientClick="return confirm('Are you sure you want to delete?')"
CommandArgument="<%# ((GridViewRow) Container).RowIndex %>"
CommandName="y" ><img src="Images/A5.gif" alt="Delete" border="0" /></asp:LinkButton>
</ItemTemplate>
<pre lang="xml"><asp:ButtonField CommandName="Updateit" Text="Button" />
</Columns></asp:GridView>

code:



void GridView1_RowCommand(Object sender, GridViewCommandEventArgs e)
{


if (e.CommandName == "y")
{
Response.Write("hello");
}


}
