textbox

问题 I have this class: public partial class Window1 : Window { public String Name2; public Window1() { InitializeComponent(); Name2 = new String('a', 5); myGrid.DataContext = this; } // ... } And I want to display the string Name2 in the textbox. <Grid Name="myGrid" Height="437.274"> <TextBox Text="{Binding Path=Name2}"/> </Grid> But the string isn't displayed. Also, if the string Name2 is updated periodically using a TimerCallback , do I need to do anything to make sure the textbox is updated

问题 I'm writing a custom TextBox that upon gaining focus changes its border style. As adding a border causes the control to overlap with those neighbouring it, I temporarily bring the text box to the front of the dialog (using textBox.BringToFront() ). However, once editing is complete and focus is lost, I would like to send the control back to its original position in the Z-order. Is this possible (preferably in a simple way!) 回答1: Call the GetChildIndex and SetChildIndex methods of the parent's

问题 I was trying to find the solution for this but nothing works. I have around 650 textboxes named : A001A, A002A...A600A and I would like to put values in those texboxes for instance "example value". I've found solution to put values in all textboxes in a form, but in mine there are those with some other values. Next solution is this one : Dim textBoxArr() As TextBox = {A2, A3, A4, A5, etc..} For Each tb As TextBox In textBoxArr Select Case tb.Text Case "RESNO" tb.Text = "-15,55,0" Case "DOGAL"

问题 I'm working on a VBA project to automate the Excel tool for a service desk queries tracker. I want, once the command button is clicked, to copy the content from a textbox to another worksheet row. If I repeat the task, the textbox content should be saved in the next empty cell of the same row. I used this macro: Private Sub CommandButton1_Click() TextBox1.Text = "" TextBox1.Copy 'TextBox2.Copy 'TextBox3.Copy Range("A2").Select Do If IsEmpty(ActiveCell) = False Then ActiveCell.Offset(1, 0)

问题 I wish the containing element (either a or element) to automatically expand vertically to accommodate text that has reach the end of line. Is there a way to do this with plain HTML elements? If not, can I do this using javascript? Thanks. 回答1: Sorry, but there is no way to this in plain HTML. With Javascript it's possible though. Take a look at jQuery plugin: autoResize. Note: this is a plugin for jQuery. Also, see this thread for more jQuery alternatives. 来源： https://stackoverflow.com

问题 I'd like to resolve a small quirk I've been having. It's not really a quirk but rather a behavior I'd like to change if possible. If I use a {N:2} StringFormat/ConverterCulture, a TextBox is forced into having a decimal mark always (even during the process of inputting text). I mean, you can't delete the dot or the comma at all, you must be able to figure out you have to move to the next "field" of the number in order to edit the decimal points by either clicking with the mouse there or

问题 Looking for a bit of help to modify some already-working JavaScript. I am using a piece of JavaScript along with a filtered textbox, the filtered text box only allows {1234567890,-} The below JavaScript works and prevents the user from entering more than 1 decimal I want to also add a dash/minus {-} to the allowed characters and prevent duplicates <script type="text/javascript"> function PreventDuplicateDecimal(evt) { var charCode = (evt.which) ? evt.which : event.keyCode; var itemdecimal =
