Check to see if a RadWindow is already open

[Abhijit]

Hi,

I am showing a RadWindow on error like this:

string confirmText = ((TextBox)control).Tag + " is a required field";
                               RadWindow.Alert(confirmText);

I am looping through several controls like this and showing a RadWindow for each time a require isnt met.
I would ideally like to check if an alert is already visible and if it is then dont show anymore alerts.
How can I check to see if a RadWindow is already open ?

Hello,

I can suggest you to use the RadWindowManager.Current which gets the singleton instance of the opened window and check if there is already opened one, if not then open a new one, for example:

private void RadButton_Click(object sender, RoutedEventArgs e)
        {
            MyWindow newWindow = newMyWindow();
            var opend = RadWindowManager.Current.GetWindows();
            if(opend.Count == 0)
            {
                newWindow.ShowDialog();
            }
        }

Hope this helps.
