listbox

问题 i'm new to visual studio and working on a project in visual basic. I am additing data to listbox from database that i need to access later.. Can we add extra data to listbox items as we can do with following html ?? <option name="harry" age="10" value="1">My name is harry</option> any ideas please ??? regards 回答1: You don't "attach" any data (whatever that means) to any UI elements in WPF, simply because UI is not Data. If you're working with WPF, you really need to understand The WPF

问题 I'm still new here so please consider. My question is that I have two forms, (form1 and form2). In form1 there's a listbox with customers names on it.

When I click a name on the listbox it displays the rest of the info but only on that form, I can't get it to display on another form. I'm coding it using

问题 I'm usting an asp:ListBox and I understand that to deselect items the user needs to hold down control while clicking on a selected item. Is there a way to make it that clicking on a selected item will deselect it without holding down control? 回答1: You can, but not in ASP.Net. You need to change the client-side HTML, meaning you need to code it using Javascript, to change the default behaviour or a select box. Something like: <script> function MyHandle(oSelect) { (change behaviuor here, using

问题 I have a Form Control list box with multiple iteams. I would like a certain cell on the spreadsheet to display the contents of the list box item the user selects and change if the user makes a different selection.

问题 Is there a proper way to align items to the right for ListBoxes from the .net Windows.Forms? You can use example_box = ListBox() example_box.RightToLeft = RightToLeft.Yes This enables the right alignment, but also prints your items right to left. Also the formatting does some really strange things here: '% one two 4.72' gets displayed as 'one two 4.72 %' For digits only this works quite well, but feels rather wonky. Are there better solutions? 回答1: RightToLeft layout is meant for the Arabic

问题 I have a ListBox control populated with several ListBox items. Each item contains a "Proceed" button and a "Postpone" button. I would like to hide that ListBox item (presented as a row in my case) once the "Postpone" button is clicked. The code I have currently doesn't seem to have any effect.
