textbox

问题 I have the following code: //All elements edited below have already been defined in MainPage.xaml int index = Window_1_Document_Page_1.Children.IndexOf(sender as TextBox); //Window_1_Document_Page_1.Focus(FocusState.Programmatic); Window_1_Document_Page_1.Children.Remove(sender as TextBox); Before deleting sender as TextBox , how do I set the focus to the TextBox above it? Thanks in advance. 回答1: Maybe there is a more elegant solution, but this should work: //Get index of control you want to

问题 I have an application that has menu keyboard shortcuts and text boxes. I want the keyboard shortcuts to be disabled when the text box has focus, but I can't figure out an easy way to do this. I could handle the text box's PreviewKeyDown event, but sending a KeyDown event doesn't cause the TextInput event to trigger so I'd have to manually trigger the TextInput event myself, and I'd have to make sure that every text box overrides the PreviewKeyDown event and creates a TextInput event. Is this

问题 I would like to skip a part of validation and just make it so the text-box can't have anything I don't want in it. The intention is to allow backspaces, spaces, and letters : d,r,i (upper and lower) be entered. How can I make it so that no special characters get entered like {}, !, :;", etc.? Private Sub txtParty_KeyPress(sender As Object, e As KeyPressEventArgs) Handles txtParty.KeyPress 'allows only numbers, letter, space, and backspace If Char.IsControl(e.KeyChar) = False And Char

问题 I am currently working on an user control to add some more functionality to a TextBox: Ellipsis trimming if the text is to large and the TextBox has lost the focus Label in front of the TextBox Validation on error I found an example for ellipsis. This example stores the current value of the TextBox in a dependency property and sets the TextBox.Text property if the element got/lost the focus.

问题 I am custom drawing a text box and now I am implementing the part where the user can click on a line and have the cursor move to where he clicked. I know how to get the row of text he clicked on because the character height is constant across all fonts, but not the column, because I'm not sure how to say "get me all the text that can be drawn before this amount of pixels," and because character width is not consistent unless you're using a fixed-width font, which is not a guarantee. So I have

问题 Hello everyone I'm using a RFID scanner that puts the scanned code in whatever text field available at scanning time. For instance, it could put the text inside a cell in Excel or in the address bar of a web browser. I made an application with a textbox that receives the input sent by the scanner, but I want to disable user-input (keyboard). I tried setting the textbox property "read only" to true, but then the text is not displayed in the textbox. How can I do that? Thanks in advance :) 回答1:

问题 I have an application that allows the creation and running of automated testing scripts. The test scripts themselves are xml files that are meant to be portable, which means that once one is configured it should work on any computer. One of the configuration settings saved in the xml files is the location of builds to copy over. Depending on the setup of the computer root folder can be different, for example on my computer I may be looking at F:\Builds\2-QA\ClientA where as another machine it
