Hello Use Text changed event : void UpperCase_TextBox_TextChanged(object sender TextChangedEventArgs e) { var tb = (TextBox)sender; var selectionStart = tb.SelectionStart; var selectionLength = tb.SelectionLength; tb.Text = tb.Text.ToUpper(); tb.SelectionStart = selectionStart; tb.SelectionLength = selectionLength; }
