hi!

I have a XBAP project for web, and I have a Page that shows a telerik components. I have a RadWindow as a usercontrol in this way:

My problem is when I try to show this window in my main program by clicking a button, code is like this:

frmDialogoEntradaDatos frmDialogo = new frmDialogoEntradaDatos();

frmDialogo.Mensaje = resxUsuarios.titSolicitudPassword;

frmDialogo.TipoDialogo = frmDialogoEntradaDatos.Tipo.TEXTO_PASSWORD;

frmDialogo.OnClose += new CloseEventHandler(EstablecerContraseña);

frmDialogo.Show();

frmDialogo is never shown, not even using ShowDialog(). I try to test original RadWindow instance like this:

RadWindow frmDialogo = new RadWindow();

frmDialogo.Width = 300;

frmDialogo.Height = 180;

frmDialogo.ShowDialog();

but nothing happen, but when using RadWindow.Alert(new DialogParameters() ... ); Works fine!

Thanks for your help

Hi!

I guess I found the problem. When I instance a RadWindow in any part of project works fine, except when it is after a MessageBox.Show or into its scope. For example:

public partial class Prueba1 : Page

{

public Prueba1()

{

InitializeComponent();

}

private void button1_Click(object sender, RoutedEventArgs e)

{

RadWindow frmDialogo2 = new RadWindow();

frmDialogo2.Width = 300;

frmDialogo2.Height = 180;

frmDialogo2.ShowDialog();

}

in this case it works perfectly!!!

but in this case:

public partial class Prueba1 : Page

{

public Prueba1()

{

InitializeComponent();

}

private void button1_Click(object sender, RoutedEventArgs e)

{

MessageBox.Show("Hello World TODAY");

RadWindow frmDialogo2 = new RadWindow();

frmDialogo2.Width = 300;

frmDialogo2.Height = 180;

frmDialogo2.ShowDialog();

}

It doesn't work, frmDialogo2 is not shown or may be is loaded but is hidden. Even in this case it's not shown:

if (MessageBox.Show("Press Yes if you agree", "Question", MessageBoxButton.YesNo, MessageBoxImage.Question) == MessageBoxResult.Yes)

{

RadWindow frmDialogo2 = new RadWindow();

frmDialogo2.Width = 300;

frmDialogo2.Height = 180;

frmDialogo2.ShowDialog();

}

BUT, curiously in this case it works:

RadWindow frmDialogo2 = new RadWindow();

frmDialogo2.Width = 300;

frmDialogo2.Height = 180;

frmDialogo2.ShowDialog();

MessageBox.Show("Hello World TODAY");

I need in some cases to use MessageBox due to it freezes pages (It acts as modal) waiting for a button click.

How can I do to resolve this combining MessageBox and RadWindow?

thanks

Hello Ramiro,

Thank you for the details.

I have tried to reproduce the issue with the Q3 release assemblies, but to no avail. Attached I am sending you a short video in which you can observe my attempt. Please let me know if I am doing something wrong.
Please send us a sample project in which the issue is reproducible and the version of the assemblies which you are using. In that way we will be able to track down the source of the problem and provide you with a solution for it.

Looking forward to your reply.
