C# – Listbox with Custom Listitem — Prevent Selection

clistboxuser-controlswpfwpf-controls

I have a listbox that uses a UserControl as the item template. Inside the UserControl, I have an image (an X) that when clicked, sends out event to remove the UserControl(listitem) from the listbox.

Is there a way to prevent the listbox from selecting that item when a user clicks on the image but still allows listitem selection for everything else in the control?

Make sure you mark the event as handled when the user clicks the Image:

private void ImageClicked(object sender, RoutedEventArgs e)
{
    //send out event to remove UserControl

    //ensure the event doesn't bubble up further to the ListBoxItem
    e.Handled = true;
}

A ListView is a specialized ListBox (that is, it inherits from ListBox). It allows you to specify different views rather than a straight list. You can either roll your own view, or use GridView (think explorer-like "details view"). It's basically the multi-column listbox, the cousin of windows form's listview.

If you don't need the additional capabilities of ListView, you can certainly use ListBox if you're simply showing a list of items (Even if the template is complex).

C# – Selecting a Textbox Item in a Listbox does not change the selected item of the listbox

We use the following style to set a PreviewGotKeyboardFocus which handles all events of TextBox control and ComboBoxes and such:

    <ListView.ItemContainerStyle>
        <Style TargetType="ListViewItem">
            <EventSetter Event="PreviewGotKeyboardFocus" Handler="SelectCurrentItem"/>
        </Style>
    </ListView.ItemContainerStyle>

And then we select the row in code behind:

    protected void SelectCurrentItem(object sender, KeyboardFocusChangedEventArgs e)
    {
        ListViewItem item = (ListViewItem) sender;
        item.IsSelected = true;
    }
