Hide root node

Hi,

My data hierarchy has a single root node. It is always single and always the same.
Is it possible just to hide it and show only items starting from the second level?

Testrash.

Clicking on first child row not setting SelectedItem?

As mentioned in a previous post I have a hierarchical gridview. On the child gridview I'm using the following binding to propogate selecteditem back up to the parent:
SelectedItem="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType=telerik:RadGridView, AncestorLevel=1}, Path=SelectedItem, Mode=TwoWay}"

This seems to work in almost every case, except when I click on the first row in one of the child gridviews. For some reason this doesn't seem to change the SelectedItem as I would expect.

How to allow only a single selected row in a hierarchy

Using a hierarchy view similar to the Custom Hierarchy demo, I want to allow the user to select only a single row of data (regardless of what tier that data is at). Further, I want to be able to bind to the currently selected row. I saw the demo on how to do this with a single-tier gridview which seems to get me halfway there - I just need to further extend that to the children as well.

RadTabControl in GridView details changes selected tab when scrolling grid

Hi,

In your WPF GridView demo, First Look, if you expand a few rows, then choose a tab other than the first, when you scroll the GridView so that the row goes out of view and then you scroll it to reappear, the tab changes to the first one and there is a noticeable delay and jump of the scroll thumb.

I was creating a very similar arrangement and I'd like to know if there's a way to stop this behavior so that the selected tab remains constant while scrolling.

Thanks,

SP

Cannot maximize/minimize when binding using Itemsource

Hi, I am using the tileview control that will bound to items at runtime.
When the tileview contains explicit tileitems like shown below I am able to maximize / minimize the tiles and also have a scrool bar as expected.

<telerik:RadTileView Name="radTileView1" MinimizedRowHeight="200" MinimizedColumnWidth ="200" >

<telerik:RadTileViewItem></telerik:RadTileViewItem>

</telerik:RadTileView>

However , when I bind the tileview to using itemsource to a List of items like shown below, I am unable to maximize, minimize the tiles. What am I doing wrong ?

<telerik:RadTileView Name="radTileView1" ItemsSource="{Binding}"

MinimizedRowHeight="200" MinimizedColumnWidth ="200" >

</telerik:RadTileView>

Note: The user control that houses the tileview control has it's data context set to the list .The tileview does show the correct number of tiles corresponding to the number of items in the list, but does not let me maximize or minimize.

RadDocking with RadRibbonWindow in Windows7..

I develop some application and use RadRibbonbar with RadRibbonWindow.

I add RadDocking Window to the application.
It is okay in Windows 7's Aero Theme,
but if I change the theme to Windows classic theme, the application is just crushed..

it doesn't have any problem when I use RadDocking window and Default WPF Window together,
but with RadRibbonWindow, it happens.

I guess it cause using RadDocking and RadRibbonWindow together in Windows7's Classic Theme..
Is there any solution to resovle that?? Please help.
