Hi,
You can prevent a DirectEvent on client side returning false from its Before handler.
But I want to Made a Judgment on server!Quote:

Do you need a separate request to server to determine should DirectEvent be fired or not?
What about checking the condition withing a DirectEvent handler and do some actions or do not?
I mean to organize the things something like this.
Example
Code:<%@ Page Language="C#" %>
<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>
<script runat="server">
protected void TestDirectEventHandler(object sender, DirectEventArgs e)
{
bool someCondition = true; //this is your judgement
if (someCondition)
{
X.Msg.Alert("DirectEvent", "Hello from Server!").Show();
}
}
</script>
