trying to open new window form

[Monika]

I'm workin on a windows application and using dock panal. I have button and images under dock panel and firing button_click, images_click events. It opens the new window form. In windows-Vista, the functinaolity is running as I want. But when I installed the application in windows-XP, the events don't fire. Application hangs up. Any body has any idea?

Hi Monika,

We have not found any issues related to events of child controls hosted in a DockPanel object. If you continue to experience it, please send me a simple project to reproduce it locally. It will allow me to address any potential issue faster.

Thank you in advance.

Sincerely yours,

Julian,
I have a groupboxs in my application and docking manager is in one of the groupbox say groupbox1. I set the groupbox1.visible to false. And in code I set it's to true. Whenever I changed the visible property of groupbox, any events of button in dock panel doesn't fire. Application hangs up. Here is a test application...
Test.vb

Imports

Telerik

Public

Class TestForm

Public Sub New()

InitializeComponent()

End Sub

Private Sub TestForm_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

Me.GroupBoxProductDetail.Visible = True

End Sub

 

Private Sub rbtnColorOptions_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles rbtnColorOptions.Click

MessageBox.Show(

"Hello")

End Sub

 

End

Hello Monika,

We have tested your sample code and all works fine. Please build a new form with the desired layout and reattach all events. It could be the case that the current design layout of the form is invalid.

If you have additional questions, please contact us.

This test code runs in windows vista perfectly but not in windows xp. Did you try to run on windows xp?

Hi Monika,

Thank you for writing.

I have tested the provided code again and have determined that it has an invalid design layout. In Windows XP it builds without any exceptions, but at runtime it freezes and does not display the docking windows and the group box properly.

I have only recreated the DockingManager in the same form with two DockPanels and one button (as your example) and everything gets to work normally. The button's click event ia raised without any problems too. Please try to recreate the DockingManager in your actual project and let me know if that does not solve your problem.

Do not hesitate to contact me again if you need additional assistance.

All the best,
