[FIXED] [V0.7] AjaxEvent before="return false" still hits server
Another tricky one. If I return false in an AjaxEvent's before handler, the AjaxEvent still fires but doesn't return anything back to the client. Below is an example. Make sure to run in debug or use Fiddler to watch the request to the server. Notice that the server method is called, but the label is not updated on the client. The server method shouldn't be called in the first place.
<body>
<script runat="server">
Protected Sub UpdateLabel(ByVal sender As Object, ByVal e As Coolite.Ext.Web.AjaxEventArgs)
Me.lblTimeStamp.Text = DateTime.Now.ToLongTimeString
If System.Diagnostics.Debugger.IsAttached Then System.Diagnostics.Debugger.Break()
End Sub
</script>
<form id="form1" runat="server">
<ext:ScriptManager ID="ScriptManager1" runat="server">
</ext:ScriptManager>
<ext:Button runat="server" ID="btnAjax" Text="Ajax">
<AjaxEvents>
<Click Before="return false;" OnEvent="UpdateLabel">
</Click>
</AjaxEvents>
</ext:Button>
<ext:Label runat="server" ID="lblTimeStamp">
</ext:Label>
</form>
</body>
