    Our application has a Telerik Tree and Grid. We allow drag and drop between the Tree and Grid and within the tree. When we drag and drop into the tree and node over which it moves gets auto expanded. How can we prevent this?

    We saw a solution for a similar problem on the ASP .NET forum.

    Is there one for WPF?

    Hi Sunandini,

    You can use RadTreeView's DropExpandDelay property and set to some large quantity.

    treeview.DropExpandDelay = TimeSpan.FromMinutes(60);

    Please have a look at this forum thread. Also, I have attached my sample project for further reference. Let me know if this is of any help.

    Kind regards,
