Not a but? Redisplay of Window

[Cuthahotha]

Getting an error when trying to display a radwindow a second time.

works fine on the first time I call it.  After it closes, and I try to re-execute the code to display it, i get the following error in my generic top level silverlight error handler.

"Exception has been thrown by the target of an invocation."

I'm sure its me, but not sure what I'm missing.

Heres the code that opens the window.

private void cmdAdd_Click(object sender, RoutedEventArgs e)

{
    frmNew.Closed +=

new EventHandler<WindowClosedEventArgs>(OnWindowClosed);

    txtNew.Text =

"[Enter Item ]";

    frmNew.Show();

}

And teh code that executes on a button push from inside the form.

 

private void OnBtnOkClicked(object sender, RoutedEventArgs e)

{

    string newName = txtNewName.Text;

    frmNewUserStory.Close();

    if (newName != "")

        {

            //Doo a bunch of stuff

        }

}

Hi Steve,

If you want to close and reopen RadWindow you should call the Hide method for closing. You should call the Close method only when you are done with this window again (window can be garbage collected).

If you have other questions, we will be glad to help.

Hi, I have a case in which the .Close is needed.

If the window is shown over a listbox with the Drag & Drop funcionality, the Drag & Drop funcionality will stop working arround the area where the window was.

.Close() solves the problem, but it can't be shown again.

Any Ideas...??

Thanx in advance.

Hi Jaime,

This was problem with RadDragDropManager but it is fixed now. In the middle of december we will release service pack 2 which include this fix. If you need it earlier you need to open a support ticket and we will send you the hotfix.
