Are you sure you are using WPF? The painting issues seem to indicate Winforms.

Never mind. I saw the class names. You are using WPF.

First code sample should show dialog but not close the this window only after dialog is closed (because it is modal).

The second sample should work as expected. The newly created Window should be shown.

It it does not show its content at first, it can happen by different reasons related to design of Window2; one typical reason is incorrect layout. Try to call its InvalidateArrange and/or UpdateLayout. If it helps, this is not a solution yet. Check up overloaded OnContentRendered, OnRender is any. It also can be a result of incorrect behavior on window resize events. just for tests, make is resizeable (if it is not) and check if it does not screw up layout when you manually resize it.

Solution 2

Ok, I could not reproduce your problem. I do this in a button click handler on the main form:

C#

private void button1_Click(object sender, RoutedEventArgs e)
{
    Child child = new Child();
    child.Show();
    this.Close();
}

The child window shows up correctly (no painting issues at all). So you may be doing something else in your code that's causing problems.

Thank U. but my problem was not solved. I try this code.

Any other have solution tell me pls,..

Unless you show a minimal code snippet that reproduces the bug, I don't think anyone can figure out what's wrong.

Create a new wpf project, add a child window, then try the same code out and see if that works for you. That will be a good first step in trying to establish the source of the problem.

This method is very nice. i try. but the same error was thrown.

I think its my layout problem,. (as SAKryukov told) if i give time to press its not happen,. then i find a solution. i post that answer 3.,
