listbox

问题 I'm making a Windows Form project that will search for files in the specified folders in my spare time. So far, I've got my TreeView that displays folders just like in the Windows Explorer. I also have a ListBox that will store all the search results. When I double click an item in that list, I want to have the option of opening the file. So far, I see three ways of doing this: Having the ListBox display the full path. Using a global List or Array to keep track of the full paths, while the

问题 I am in a big trouble. I read 4 stackoverflow question and one blogpost. I have tried 5 different approach to view the selected items in a multiple selectlist. I have no success. The multiple selectlist is generated, but it does not select the items. I have no more idea.

问题 I want to implement incremental search on a list of key-value pairs, bound to a Listbox. If I had three values (AAB, AAC, AAD), then a user should be able to select an item in the available list box and type AAC and this item should be highlighted and in focus. It should be also in incremental fashion. What is the best approach to handle this? 回答1: I realize this is extremely late... however, having just implemented this, I'll leave it here in the hope that it will help someone. Add a handler

问题 I'm writing an C# App (WinForm) with a ListBox having content added by the user. Now, I could have a ordinary button under the ListBox to remove items, but I would like to have the button right next to the content, thus being inside of the ListBox. Like this: Content 1 | X Content 2 | X ... Content 5 | X The problem is that I lack experience in .NET so I have no clue on how this would be possible with all the automated controls going on. I've googled it, but came up with no meaningful results
