treeview in combobox -> BringItemIntoView

[iramz]

hello,

i tried using the below implementation of radtreeview

http://blogs.telerik.com/blogs/posts/09-08-27/treeview_in_combobox_take_3_silverlight_3_wpf_and_radcontrols.aspx

however, i try to use BringItemIntoView to show a specific item when combobox dropdown opens, but the selected item is still not in the view. i can control the treeview to expand and all, but the item i want to be visible is still out of view (need to scroll down). any idea?

thank you!

here is how i control it on my TreeViewComboBox.cs

protected override void OnDropDownOpened(EventArgs e)
        {
            base.OnDropDownOpened(e);
            if (treeView != null && this.SelectedItem != null)
            {
                treeView.ExpandAll();
                treeView.BringItemIntoView(this.SelectedItem);
            }
        }

        public void treeView_SelectionChanged(object sender, SelectionChangedEventArgs e)
        {
            treeView = sender as RadTreeView;
        }

Hi iramz,

The BringItemIntoView method only works for the immediate children of the TreeView. We have mentioned this in the summary of the method but I agree that it can be misleading.

I answered here how you can expand to an item;

You can obtain an item by calling the GetItemByPath() method and then call its item.BringIntoView method.
