Hi ClarkSRoberts,

Every article in our documentation that uses server-side code, provides C# and VB.NET versions of that code. In your case I suggest to check the following link:
http://www.telerik.com/help/aspnet-ajax/window_settingserversideproperties.html

As you can see, to open a RadWindow from the server, you need to:

Create the window or use already created one
Set the properties that you need (Width, Height, etc.)
Set its VisibleOnPageLoad property to true
If the RadWindow is a new one - to add it to the page as a standalone control or in the Windows collection of an existing RadWindowManager.

e.g.

    
            'Create a new window add it dynamically 
        
            'The window will inherit the default settings of parent WindowManager 
        
            Dim newWindow As New Telerik.Web.UI.RadWindow() 
        
            newWindow.NavigateUrl = "http://www.sitefinity.com" 
        
            'Top and Left can be used in conjunction with the OffsetElementId (if no OffsetElementId is specified, the top left corner of the browser window is used 
        
            newWindow.Top = Unit.Pixel(22) 
        
            newWindow.Left = Unit.Pixel(0) 
        
            'OPTION 1 
        
            'Add the newly created RadWindow to the RadWindowManager's collection 
        
            'WindowManager.Windows.Add(newWindow) 
        
            'OPTION 2 
        
            'since in the for ASP.NET AJAX version you can have a RadWindow outside of a RadWindowManager 
        
            'as a separate control, you can add the newly created RadWindow directly to the form's Controls collection 
        
            form1.Controls.Add(newWindow)

Hello Levefaude,

You can try the following code snippet to open RadWindow on button click.

VB:

Protected Sub Button1_Click(sender As Object, e As EventArgs)

Dim script As String = "function f(){$find(""" + RadWindow1.ClientID & """).show(); Sys.Application.remove_load(f);}Sys.Application.add_load(f);"

ScriptManager.RegisterStartupScript(Me, Me.[GetType](), "key", script, True)

End Sub

OR

Protected Sub Button1_Click(sender As Object, e As EventArgs)

RadWindow1.VisibleOnPageLoad = True

RadWindowManager1.Windows.Add(RadWindow1)

End Sub

Thanks,
Princy.
