listbox

I'm having trouble in multiple items selection in an ListBox. I've tried deriving new control from Selector and writing ListBox helper class which did not work (as expected). The issue with Selector class is, it does not expose SelectedItems and it's hell to bind the property and manipulate it with selection changed event. The issue with ListBox Helper class is, I'm getting the required data on multiple selection but it never hits the bound property. Does anybody know a better way to implement multiselect listbox? Thanks in advance... The ListBox has multiple selection already implemented.

I have a ListBox and want the selection-mode to be extended. Also I want have to implement drag and drop functionality. The problem now is, that if the mouse is clicked on a selected item, it will be immediately be selected as single selection instead of waiting to the mouse-up-event for doing this. Due to this behaviour, start dragging multiple items is for the user quasi impossible because always he clicks on the selection to start dragging, the selection changes to the item that is under the mouse and starts the drag-operation with this item. Is there a good workaround for this problem or

I wonder how to get or compute actual width of ListBox without Vertical Scrollbar if visible. What I want to do is changing width of each items inside ListBox without being covered by Vertical Scrollbar . Width="{Binding ActualWidth, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type ListBox}}} At least, above binding tell me the actual width of ListBox , but this one does not handle width of vertical scrollbar. Is there any good way to solve this? Try binding to the ViewportWidth property of the containing ScrollViewer instead. Like this: Width="{Binding Path=ViewportWidth,

I have a ListBox showing items using the following DataTemplate: <DataTemplate x:Key="PersonTemplate" DataType="{x:Type DAL:ResultItem}" > <StackPanel Width="280" > <TextBox BorderThickness="0" IsReadOnly="True" Background="Transparent" Text="{Binding FullName1, Mode=OneWay}"/> ... </StackPanel> </DataTemplate> I am using a transparent, read-only, borderless TextBox as opposed to a TextBlock because I want users to be able to select the text for copying. Should I do it differently? How can I write this so that when the user clicks on the TextBox, the ListBoxItem gets selected as well? Thanks!

A killer problem I've had in excel UIs since as long as I can remember, is with listbox scrolling. When you have more elements in a listbox that can be displayed, a scoll bar will appear. In certain conditions, however, scrolling the bar all the way to the bottom of the list and releasing it, will "jump" the bar a notch upwards, and you won't be able to see the last item in the list. This is illustrated here: There are many forum posts presenting this issue, and the solution has always been "Set the integral height property to false, and then set it to true again." What this does is slightly

I have a UserControl (XAML below) that has a ListBox that I want to display images inside a WrapPanel, where images are displayed as many as will fit on one row and then wrap onto the next row etc. It works, except when the ListBox grows higher than the available space in the window, I'm not getting a vertical scrollbar, i.e. the contents get clipped. If I set a fixed height on the ListBox, the scrollbar appears and works as expected. How can I get this listbox to grow to the available space and then show a vertical scrollbar? This control is inside StackPanel inside a Grid in the main window.
