问题 Like the title says, I've got a Child form being shown with it's TopLevel property set to False and I am unable to click a MaskedTextBox control that it contains (in order to bring focus to it). I can bring focus to it by using TAB on the keyboard though. The child form contains other regular TextBox controls and these I can click to focus with no problems, although they also exhibit some odd behavior: for example if I've got a value in the Textbox and I try to drag-click from the end of the

问题 I have a masked textbox with the need to have a min/max length set on them. When these conditions are met a button becomes enabled. I was thinking of handling the TextChanged event to determine the length of the entered text and set the buttons enabled value.

问题 I've set up a Telerik RadMaskedTextBox with a Mask of "####-####". The problem is, when I later grab the value from this box it returns as "########". I'm unfamiliar with MaskedTextBoxes but I'm guessing that this is the default way it's supposed to return my value. How can I set the "-" as a literal character in the RadMaskedTextBox so it returns the whole value? ex. "1234-5678" instead of "12345678" 回答1: Use TextWithLiterals instead of Text property. 回答2: I'm unfamiliar with the Telerik

问题 I am using maskedTextBox.SelectAll() to highlight the text in the MaskedTextBox in the Enter and MouseDown events. It works when I use the mouse, but I go to that textbox by pressing the Tab key, it does not work. What am I missing here? 回答1: Have you tried the GotFocus event? When you change the focus by using the keyboard (TAB, SHIFT+TAB, and so on), by calling the Select or SelectNextControl methods, or by setting the ContainerControl.ActiveControl property to the current form, focus
