Once you click the delete button it shows confirmation message then if the user select “ok “ then delete method will be call, else if “cancel” nothing should be happens.
In client side(Default.aspx)
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false" DataKeyNames="Id" OnRowCommand="GridView1_RowCommand" BorderWidth="1px" CellPadding="3" CellSpacing="2" >
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:LinkButton ID="lnkdelete" OnClientClick="returnconfirm('are you want to delete')" runat="server" CommandArgument='<%# Eval("Id") %>' Text="Delete" CommandName="lnkDelete"
ForeColor="#BC4510" />
</ItemTemplate>
</asp:TemplateField>
</Columns>

In Code behind(Default.aspx.cs)
protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName == "lnkDelete")
{
int employeeID = Convert.ToInt32(e.CommandArgument);
DeleteEmployee(employeeID);
}
}
