I have an application with a tab control and several textboxes in each tab and when the user says so, I would like every text box in the window (called MainWindow) to be cleared. I used the method described here, but it only seems to work for the textboxes in the tab that it is in focus.
Try this:
void ClearTextBoxes(DependencyObject obj)
{
TextBox tb = obj as TextBox;
if (tb != null)
tb.Text = "";
for (int i = 0; i < VisualTreeHelper.GetChildrenCount(obj as DependencyObject); i++)
ClearTextBoxes(VisualTreeHelper.GetChild(obj, i));
}
private void Button_Click(object sender, RoutedEventArgs e)
{
ClearTextBoxes(this);
}
