Treeview extended with textbox at top

[GJ]

Hello, i want to extend functionality of the treeview with a textbox at top for search funtions. I'm trying to make with code similar to this (see below) but Treeview don't have "Item" like TextBox to get the instance. How can i get this functionality?

private static void AddIconToTextBoxElement(RadTextBoxElement textElement, ImagePrimitive icon)

{

    var item = textElement.TextBoxItem;

    textElement.Children.Remove(item);

    icon.SetValue(DockLayoutPanel.DockProperty, Telerik.WinControls.Layouts.Dock.Left);

    var dockPanel = new DockLayoutPanel

    {

        LastChildFill = true

    };     

    dockPanel.Children.Add(icon);

    dockPanel.Children.Add(item);

    textElement.Children.Add(dockPanel);

}

Hello Jorge, 

Thank you for writing.  

I would recommend you to create a UserControl that contains a RadTextBox docked to the top and a RadTreeView below the text box. Thus, you can achieve the desired layout and implement the custom search functionality that you want.

I hope this information helps. Should you have further questions I would be glad to help.

I know this post is several months old, but for others searching for a solution, here is a KB article that explains how to do what you user wanted, and an example control that will work out of the box.

Hello Bruce, 

Thank you for writing.  

The referred KB article is greatly appreciated. It may be suitable for some custom search scenarios in RadTreeView. I have updated your Telerik points for the community effort.
