Hi,

The reason I’m writing this email is to see if we can get a license for the "Multi Selection TreeView in WPF" since we couldn’t find any license published by you.
We would like to use the software in one of our commercial product.

If you have any commercial license or willing to confirm to us that this can be distributed under different license (preferably BSD) – it would be much appreciated.

Thank you

If I try to change the background on a item by modifying the style, when a parent is selected, visually all of the children are selected too. How do I fix this?

Hi Nicolas,

Nice approach. But the selectedItems are not in sync when a drop has occured.

This is a workaround. It works, but isn't perfect (as the reset isn't performed inmediately but with the first next selection).

1. Add the following code to EnableMultiSelectChanged:
tree.AddHandler(TreeView.PreviewDropEvent, new DragEventHandler(PreviewDrop)); (also a RemoveHandler)

2. Add the following code to the class:
private static bool possibleDropOccurred = false;
static void PreviewDrop(object sender, DragEventArgs e)
{
// Reset the SelectedItems when a drop takes place
possibleDropOccurred = true;
}

3. Change RealSelectedChanged:
{
TreeViewItem item = (TreeViewItem)sender;
var selectedItems = GetSelectedItems(GetTree(item));
if (selectedItems != null)
{
if (possibleDropOccurred)
{
selectedItems.Clear();
possibleDropOccurred = false;
}
var isSelected = GetIsSelected(item);
.....

Thanks,

Frank
