Hi!

I'm adding from the code an object to one of my recursive ObservableCollection. There is a root ObservableCollection that is set as ItemsSource. 

When I add it to my collection, I want to select it on my tree.

So how can do this? I cannot find any methods that permits me to get a RadTreeViewItem of my added object.

I've seen that: http://www.telerik.com/help/wpf/radtreeview-how-to-get-item-by-path.html but I'm not sure there will never two element with the same displayed name

Hello!
Is there a way to iterate over a RadDocking control  and check which RadPanes are floating, ans eventually make them docked also from code?

Thank you!

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

I have a tile view something like what is below. How to I set the colors of the tiles in this scenario?

<telerik:RadTileView Margin="12" Name="DashboardRadTileView" ItemsSource="{Binding}" Grid.Row="2" BorderBrush="{DynamicResource BorderBrush}" Background="{DynamicResource PanelGradientBrush}" Foreground="Black" MinimizedItemsPosition="Bottom" Padding="12">
    <telerik:RadTileView.ItemTemplate>
        <DataTemplate>
            <TextBlock Text="{Binding Path=Description}" />
        </DataTemplate>
    </telerik:RadTileView.ItemTemplate>
    <telerik:RadTileView.ContentTemplate>
        <DataTemplate>
            <StackPanel>
                <TextBlock Text="{Binding Path=Text}"/>
            </StackPanel>
        </DataTemplate>
    </telerik:RadTileView.ContentTemplate>
</telerik:RadTileView>

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?

Is it possible to disable the horizontal scrollbar? If yes how do I do this?
(RadPanelBar is bound to a HierarchicalDataTemplate).

Hi!

I've a  Tree, that has a RadContextMenu(Telerik's version of Context Menu). On every ItemMenu, I've an action.

I need to know, on which element of my Tree i've right clicked. How can I do this?

I tried to use the "SelectItem", but it seems the tree doesn't select on right click.

Thank you!

Hi All,

I am using the RadChart for WPF in my project for displaying the Chart as LineSeries, my requirment is like this:
 1) I need to add dataPoints dynamically by reading the output file for each Dataseries
  2) I need to add AdditionalYAxes for each Dataseries
  3) I need to Apply ForeGround color for each DataSeries
   4)And the same DataSeires color i need to apply color for related AdditionalYAxes
 
I have done upto the Above Three Steps and i am able to add AdditionalYAxes. But i am not able to Apply the color Style for the AdditionYAxes line and also the AdditionalYAxes is not start from X-axes, for now it is starting from X-axes one Step above.

I need to apply the color for AdditionaYAxes for the relating DataSeries and The Line should Start from X-Axes position.

i have attached my codeSnippet below:

I have attaching the Chart ScreenShot what i implemented.
Please see in Attachments
i am  calling the GenerateSeries Method every time for loading the X-Axis value and Y-Axes value.
Please any one help me how to apply color and starting position of AdditionaYAxes.
This is very urgent Requirment.

Thanks and Regards

Hi,

On my RadChart i would like to "control" x labelstep thank to a property in a ViewModel (as you see I'm using MVVM pattern).

But when i try to use this mehod, i've got this message :

System.Windows.Data Error: 2 : Cannot find governing FrameworkElement or FrameworkContentElement for target element. BindingExpression:Path=Intervalle; DataItem=null; target element is 'AxisX' (HashCode=6253391); target property is 'LabelStep' (type 'Int32')

It seems that RadChart is loosing DataContext juste for this property. Any idea ? :D I probably should affect DataContext to "AxisX" but i don't know how to do it.

Here is my code :



Thank's !
