listbox

I have a System.Windows.Forms.ListBox in multiple selection mode and a set of items I'd like to be selected. How do I do that? [Test] public void SetListBox() { var listBox = new ListBox(); var items = new List<string>{"one", "two", "three", "four"}; listBox.SelectionMode = SelectionMode.MultiSimple; listBox.Items.AddRange(items.ToArray()); var selectedItems = new List<string> {"two", "four"}; // ??? Assert.AreEqual(selectedItems, listBox.SelectedItems); } Do this: selectedItems.Select(sd => listBox.Items.IndexOf(sd)).Where(i => i >= 0).ToList().ForEach(i => listBox.SetSelected(i, true)); For:

I would like to have my WPF Listbox, which is databound, generate subclassed ListboxItems instead of the regular ListboxItems. In this case, a DataTemplate is not sufficient because I need some custom properties for the subclassed ListBoxItems. Is there a way to have the ListBox generated mySubClassedListBoxItem items for the bound data? Thanks, Bart You need to create your own subclass of ListBox so you can override the method which creates the container, e.g. public class MyListBox : ListBox { public MyListBox() { // Should get the default style & template since styles are not inherited

I want a code to insert a checkbox inside a listbox in c sharp. on selecting the checkbox all the items in listbox must get selected. You can use a CheckListBox to display a list with a check box next to each item. But to make a single checkbox that selects everything in a list, it must be outside the list box (above or below or beside it). Then you can use code like: public void SelectAllCheckBox_CheckedChanged(object s, EventArgs e) { foreach (var item in ListBox1.Items) { item.Selected = SelectAllCheckBox.Checked; } } There is no control that has a single check box inside a list: eg this is

I have met an issue of unproper selection of items in TListBox in my application with a HorzScrollBox in the form. The form has two (or more) TListBox on it. They are placed away from each other so that their absolute left coordinates difference is more than the width of the current device screen width. The error appears in the following sequence of user actions. An item is selected from the left TListBox The HorzScrollBox is scrolled to the right and the second TListBox becomes visible to user and the left one - invisible. The HorzScrollBox is scrolled back to the left. An new item is

Possible Duplicate: How to make ListBox editable when bound to a List<string>? I'm trying to set a two-binding between a List named "ListStr" object and a ListBox WPF control. Besides I want the items to be editable, so I added a DataTemplate with TextBoxes expecting that it would modify the ListStr items straight away via TextBoxes. But when I'm attempting to edit one of them, it doesn't work... Any Idea ? PS: I've tried to add the Mode=TwoWay parameter, but it's still not working Here is the XAML : <ListBox ItemsSource="{Binding Path=ListStr}" Style="{DynamicResource ResourceKey

I have an Access database with two tables: "contacts" and "country" These contain a number of fields in each. I have a query, "Filter", that brings these two tables together. I want to create a form with as many list boxes as there are fields in the query. A user can open the form and select multiple data from each list box - the row sources are tied back to the two tables above. Then on the click of a button the query would be displayed and filters would be applied dependent on the users selections in the list boxes. If nothing is selected then the query is displayed without filters.

With .NET 4.0 it appears highlighting of ListBox and ListView has changed Below is code I have used for years in several places on .NET 3.5 and highlight when not focused has stopped working on 4.0 and 4.5 <ListBox.ItemContainerStyle> <Style> <Style.Resources> <SolidColorBrush x:Key="{x:Static SystemColors.HighlightTextBrushKey}" Color="Red"/> <!-- Background of selected item when focussed --> <SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="Pink"/> <!-- Background of selected item when not focussed --> <SolidColorBrush x:Key="{x:Static SystemColors.ControlBrushKey}"

I'm trying to 'reset' a listbox in Excel VBA when a form closes. Currently when I use the userform1.hide function the form disappears but when I open it up again using the .show function it still has the previous selections in it. As someone who is relatively new to this can anyone help? The code for the listboxes is as follows: Sub CommandButton1_Click() 'Filter by Country Dim item As Long, dict As Object Dim wsData As Worksheet Set wsData = Sheets("TPID") Set dict = CreateObject("Scripting.Dictionary") With ListBox1 For item = 0 To .ListCount - 1 If .Selected(item) Then dict(.List(item)) =
