How to redraw or refresh the screen

Question

I am working on a wpf application. Here I need to use System.Windows.Forms.FolderBrowserDialog in my Wpf application.

        System.Windows.Forms.FolderBrowserDialog openFolderBrowser = new System.Windows.Forms.FolderBrowserDialog();

        openFolderBrowser.Description = "Select Resource Path:";
        openFolderBrowser.RootFolder = Environment.SpecialFolder.MyComputer;
        if (openFolderBrowser.ShowDialog() == System.Windows.Forms.DialogResult.OK)
        {
            //some logic
            openFolderBrowser.Dispose();
        }

I launch FolderBrowserDialog, select the folder and click OK, and then launch another System.Windows.Forms.FolderBrowserDialog. My problem is that when I select the folder and click OK in this FolderBrowserDialog, the shadow of the FolderBrowserDialog remains on the screen (means that my screen is not updating). I need to minimize or resize it to remove the shadow of a FolderBrowserDialog. How can I solve this problem? Any help plz?

Edit:

I have found a solution. I called the OnRender method in my wpf Window and it worked for me. He redraws everything on the screen.
