Stopping TreeViewAdv nodes changing

[Anton De Gruchy]

I need to prevent a user from selecting a node based on some validation. In the WinForms version of the TreeViewAdv I can use BeforeSelect and pass args.Cancel = true. How do I achieve the same thing with the WPF tree?

Hi,

Currently, we didnt have that feature in TreeViewAdv control. However, Your requirments will be acheived by workaround.

For instance, In selected event, you write the following code snippet,

C#

private void item1_Selected(object sender, RoutedEventArgs e)
{
if (!item1selected )
{
item1selected = true;
}
else
{
(sender as TreeViewItemAdv).IsSelected = false;
}
}

Please download the attached sample for more reference.

Please let us know if you have any questions.

Thanks for choosing Syncfusion products.
