Hi,
First you need to set the property of the ASPxMenu-> AllowSelectItem = True
and place a ASPxCallBackPanel and give it a clientinstance name for example cpanel then place all the round panels you want to put inside this callback panel and make their visible property = false
then in the ASPxMenu Event of Item Click place this line
//This line call the cpanel call back and pass to it a parameter the text of the clicked item
cpanel.PerformCallback(s.GetSelectedItem().GetText());
Then in the event of the Callback of the Panel
Protected Sub ASPxCallbackPanel1_Callback(ByVal source As Object, ByVal e As DevExpress.Web.ASPxClasses.CallbackEventArgsBase) Handles ASPxCallbackPanel1.Callback
if(e.Parameter = "SOANDSO") Then
display rount panel 1 // set visible for round panel1 to true
Else if (e.Parameter = "SoANdSo2") Then
display round panel 2 // set visible for round panel2 to true
End If
End Sub
