I take a slightly different approach by extending the Button control. Just more general purpose.

<bo:LinkButton id="Button1" runat="server" ConfirmText="Delete?" />


public class LinkButton : System.Web.UI.WebControls.LinkButton
{
    [Bindable(true), Category("Behavior"), DefaultValue("")]
    public string AlertText
    {
        get { return (string)ViewState["AlertText"] ?? string.Empty; }
        set { ViewState["AlertText"] = value; }
    }

    [Bindable(true), Category("Behavior"), DefaultValue("")]
    public string ConfirmText
    {
        get { return (string)ViewState["ConfirmText"] ?? string.Empty; }
        set { ViewState["ConfirmText"] = value; }
    }

    protected override void CreateChildControls()
    {
        string script = string.Empty;

        if (AlertText.Length > 0)
        {
            script += string.Format("alert('{0}');", AlertText);
        }

        if (ConfirmText.Length > 0)
        {
            script += string.Format("return confirm('{0}');", ConfirmText);
        }

        if (script.Length > 0)
        {
            OnClientClick = script;
        }

        base.CreateChildControls();
    }
}

You can use the Ajax ASP.NET extender for button confirmation.

<TemplateColumn>
    <ItemTemplate>
      <asp:LinkButton id="lbDelete" runat="server" CommandName="Delete" Text="Delete"/>
      <cc1:ConfirmButtonExtender ID="cbeDelete" runat="server" 
          ConfirmText="Are you sure you want to delete this record?"
          TargetControlID="lbDelete" />
    </ItemTemplate>
    <ItemTemplate>
      <asp:LinkButton id="lbCancelUpdate" runat="server" CommandName="Cancel" Text="Cancel"/>
      <cc1:ConfirmButtonExtender ID="cbeCancel" runat="server" 
          ConfirmText="Are you sure you want to cancel any changes?"
          TargetControlID="lbCancelUpdate" />
    </ItemTemplate>
</TemplateColumn>

You may be able to do something similar with another CBE on the cancel button for the edit template.

In client side script for those buttons you want to do something like

if (confirm('Are you sure you want to delete this item'))
{
   //Do logic for delete item
}

Edit

Go and put this in a .html file on your pc and open it in a browser (if its ie7 you'll get security warning just allow it, this won't happen when launched from a url):

<html>
<body>
<script>

if (confirm('You want to delete me?')
{
 alert('deleted');
}
</script>
</body>
</html>

confirm is a function;-)

i don't know where can i found "confirm" when i type confirm there is not any method call confirm

confirm is a javascript function. JavaScript and intellisense aren't the best friends. You might get some but not a ton.
