Binding carousel items to column of gridview

What is the best way to bind the items of a carousel to a column (images that are of type byte[]) of a gridView which is itself bound to a database table. I ultimately want to populate the carousel with only the images from the selected rows in the gridView. Any pointers would be appreciated.

Thanks,
Nate

gridview.selectedItem is null

i have this grid

<telerik:RadGridView x:Name="grid" ItemsSource="{Binding Path(ns:class.property)}"

SelectionMode="Single"

ShowGroupPanel="False" AutoGenerateColumns="False" CanUserDeleteRows="False" CanUserFreezeColumns="False" CanUserInsertRows="False" CanUserReorderColumns="False" CanUserResizeColumns="False"

RowIndicatorVisibility="Collapsed" Controls:StyleManager.Theme="Office_Black" EnableColumnVirtualization="False" EnableRowVirtualization="False" IsFilteringAllowed="False" Controls:RadControl.Theme="Office_Black" ReorderColumnsMode="None"
/>

now when i try to change selected item from code like this:

grid.SelectedItem = Collection[0];

the grid.SelectedItem stays null
even though Collection[0] is not null

i tried to call OnApplyTemplate before assignment but it didn't helped

i tried to do it with two way data binding and it didn't helped too

what can cause this?
and how can i solve it?

thanks

RadPane with RadTreeView

Hi there,

I have an RadPane and inside a RadTreeView. When I now change the width of the pane (by runtime) the width of the RadTreeView does not change. Equally when I undock the pane.
What did I have to do that the RadTreeView always has the width of the RadPane?

Thx
Andi

How to add images?

Hi there,

I want to add images to my TreeViewItems, but it does not work :(
I knew there are many Threads for this theme and I read many of them, but I found no answer which can help me.
I have just a simple .xaml with the Tree and 3 Items and a folder named "Icons" in the source-folder of my project.
What am I doing wrong?

<Window x:Class="TreeViewTest.MainWindow"

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

Title="MainWindow" Height="350" Width="525" xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation" Icon="/TreeViewTest;component/ics.ico">

<Grid>

<telerik:RadTreeView HorizontalAlignment="Left" Name="treeView1" VerticalAlignment="Top" IsLineEnabled="True" FontFamily="Arial" FontSize="10" ImagesBaseDir="/Icons/" IsDragPreviewEnabled="False">

<telerik:RadTreeViewItem Header="Global" DefaultImageSrc="Folder_16x16-32.png">

<telerik:RadTreeViewItem Header="Local 1" />

<telerik:RadTreeViewItem Header="Local 2" />

</telerik:RadTreeViewItem>

</telerik:RadTreeView>

</Grid>

</Window>
