[Solved] Textbox focus inside window not working

[Trude]

When I open a window (in code behind with show or showdialog) I want to set focus on a specific textbox, but it doesn't seem to work.

Below is the code:

 

 

Private Sub login_window_Loaded(ByVal sender As Object, ByVal e As System.Windows.RoutedEventArgs) Handles Me.Loaded

TextBoxUsername.Focus()

End Sub

Hello Jorn,

What I would recommend you is not to focus an element explicitly, but to put it in the first place in Xaml in the Window's content or to use the TabIndex properties of the visual elements. As I noticed that your window is called LoginWindow I guess it is opened at the start of the application. Please, notice that the Silverlight plugin must be focused in order your TextBox to be focused.

The work-around if you still want to do that with code is to focus the element asynchronously with a Dispatcher.

After going through all your suggestions it turned out that the silverlight control/plugin didn't have focus set. I somehow assumed it automatically gained focus upon loading the application, but this is obviously not the case.

The following codebehind in the usercontrol solved the problem:

 

Public Sub New()

InitializeComponent()

System.Windows.Browser.HtmlPage.Plugin.Focus()

End Sub
