Hi,

In order to capture state-change events of WebDialogWindow in order to cancel them or implement custom logic, the ClientEvent WindowStateChanging should be used. If event is canceled, then no postback occurs.

That event also can be processed on server, but it does not support "cancel" action similar to client event. However, application may change state back to original or set another desired state of dialog.

Below are examples for both cases:

aspx:

 <script type="text/javascript">
 function WebDialogWindow1_WindowStateChanging(sender, eventArgs)
 {
  var newState = eventArgs.get_newWindowState();
  //if (newState == 3) //or
  if (newState == $IG.DialogWindowState.Hidden)
  {
   // put your you custom/validation codes here
   //if (someCondition)
   //{
   // eventArgs.set_cancel(true);
   //}
  }
 }
 </script>

 <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>

 <ig:WebDialogWindow ID="WebDialogWindow1" runat="server" Height="300px" Width="400px" Modal="true" onstatechanged="WebDialogWindow1_StateChanged">
  <AutoPostBackFlags WindowStateChange="On" />
  <ClientEvents WindowStateChanging="WebDialogWindow1_WindowStateChanging"></ClientEvents>
 </ig:WebDialogWindow>

aspx.cs:

 protected void WebDialogWindow1_StateChanged(object sender, Infragistics.Web.UI.LayoutControls.DialogWindowStateChangedEventArgs e)
 {
  if (e.NewState == Infragistics.Web.UI.LayoutControls.DialogWindowState.Hidden)
  {
   this.Label1.Text = "dialog was hidden";
   //((Infragistics.Web.UI.LayoutControls.WebDialogWindow)sender).WindowState = e.OldState;
   //((Infragistics.Web.UI.LayoutControls.WebDialogWindow)sender).WindowState = Infragistics.Web.UI.LayoutControls.DialogWindowState.Normal;
  }
 }

If you can live with it,another suggestion is to eliminate the close button, turn the modal attribute true and handle everything via button events.

 I have this working now...  i closed my VS2005 and restarted it and now it is working.

 Now, i can try to get the references to the WebDataInput text boxes on the .aspx page that i am displaying as the ContentUrl for the WebModalDialog. 

 thanks

hi;

 i too am trying to get the close button to respond to a server-side event ( WindowStateChange ).  i have looked at the links suggested above and this is what i have done.   i did not understand the help link to the StateChanged Event.

 i have set the autopostback flag to true to windowstatechanged event.

  and i have created a server-side StateChanged event.

    Private Sub WebDialogWindow1_StateChanged(ByVal sender As Object, ByVal e As Infragistics.Web.UI.LayoutControls.DialogWindowStateChangedEventArgs) Handles WebDialogWindow1.StateChanged
        Stop
        If e.NewState = Infragistics.Web.UI.LayoutControls.DialogWindowState.Hidden Then
            If e.OldState <> Infragistics.Web.UI.LayoutControls.DialogWindowState.Hidden Then
                lblReturnedData.Text = "window is closed"
                lblReturnedData.Visible = True
            End If
        End If
    End Sub

  this event is never being fired.   is this all that is necessary to wire-up the StateChanged event?

  i do have the _Moved event server-side and it is being fired, however, it is fired after the window is closed.

Stop

End Sub

  Thanks for your help.
