Hi

I have an app that I have a docked component and the existing panes are saved/loaded via isolated storage. This has been working fine. I've now added a new pane to my app, via XAML, but when it's run on a system where the layout is loaded it is never displayed.

If I exclude the layout load step the new pane appears, so I guess in the load it's overriding the entire layout of the dock component (as expected). If I then manually add a step in the LoadLayout method to add the pane, that also seems to be ignored.

Here is the important code and the examples of what I've tried:

using (IsolatedStorageFile storage = IsolatedStorageFile.GetUserStoreForAssembly())
{
    try
    {
        using (var isoStream = storage.OpenFile("RadDocking_Layout.xml", FileMode.Open))
        {
            this.radDocking.LoadLayout(isoStream);
        }
    }
    catch (Exception ex)
    {
        logger.Error("Reading pane layout");
    }
}
 
if (panelMap.PaneGroup == null)
{
    //this doesn't work
    radDocking.Items.Add(panelMap);
 
    //neither does adding into existing pane group
    paneTest.Items.Add(panelMap);
 
    //neither does building a new group for the pane to go into
    RadPaneGroup rpg = new RadPaneGroup();
    rpg.Items.Add(panelMap);
    radSplit.Items.Add(rpg);
}
 
//Part of the XAML
<tel:RadDocking Name="radDocking" HasDocumentHost="False">
    <tel:RadSplitContainer x:Name="radSplit" Width="365" InitialPosition="DockedLeft" Orientation="Vertical">
        <tel:RadPaneGroup x:Name="paneTest">
            <tel:RadPane x:Name="panelMap" Header="Map" CanUserClose="False" Height="24" VerticalAlignment="Bottom" IsSelected="True" tel:RadDocking.SerializationTag="Map">

 
I've obviously got something missing, but when I've looked a the examples I can't seem to figure out what.

Thanks...

We have a problem that is actually a result of the backstage panel in the RibbonView, but I think the solution lies with the docking control.

In our application, the user can open a number of documents, all of which host WinForms controls. Unfortunately, when then backstage panel is opened on the RibbonView, the WinForms controls still show through. My understanding is that this is an issue with airspace.

My theory was that we could hide the documents when opening the backstage panel, but I'm unclear as to how we could do this. I was hoping I could set the visibility of the documenthost or panegroup, but this has no affect. Even setting the documentpane only hides the tab at the top.

Any help would be appreciated.

Thanks

Hi,
I've got a schedule view set up and uses some resource types to group appointments to particular categories.

I need to be able to show a single appointment that goes across all categories.

How can I achieve this?

Thanks,
Rob

I have a series consisting of an x-axis being DateTime and the Y-axis a numeric value. The datapoints are ranges and have a start and end date. Sometimes they have null values for the Y-axis, but still get an X-axis. I have attached a crude mockup of what I am trying to acheive.

The step-line chart comes the closest, but wondering if there was a chart type in the Telerik suite that could explicitly deal with ranges or if I am just thinking about this all wrong.

Thanks in advance.

We are getting Ui Automation related error using ScatterLineSeries and BarSeries..
So I tried to create a class derived from BarSeries
public class CustomLineSeries : LineSeries
{
       protected override AutomationPeer OnCreateAutomationPeer()
       {    return null;   }
}
The issue is I cannot seem to get the series plotted when using derived BarSeries when I use the below code...
Issue seems to be with the Style tageting CustomBarSeries... Removing this style I can see the BarSeries in chart.
But the question is HOW do i set the Style of the derived BarSeries Class...

<telerik:RadCartesianChart.SeriesProvider>
<telerik:ChartSeriesProvider Source="{Binding Series}">
   <telerik:ChartSeriesProvider.SeriesDescriptors>
       <telerik:CategoricalSeriesDescriptor ItemsSourcePath="ChartsDataPoints" CategoryPath="X" ValuePath="Y" TypePath="SeriesType">
           <telerik:CategoricalSeriesDescriptor.Style>
               <Style TargetType="charts:CustomBarSeries">
                    <Setter Property="CombineMode" Value="None"/>
                    <Setter Property="DisplayName" Value="{Binding LegendTitle}"/>
               </Style>
           </telerik:CategoricalSeriesDescriptor.Style>
         </telerik:CategoricalSeriesDescriptor>
     </telerik:ChartSeriesProvider.SeriesDescriptors>
</telerik:ChartSeriesProvider>

In code behind I had Set SeriesType as typeof(CustomBarSeries)....

Have been breaking my head on this... any help is appreciated..

Can I display the Items in a drop downlist for a RadComboBox through a Grouping mechanism and if only allow items from the same group to be selected. 

There is suppose to be a IsGrouping capability of a ComboBox does it work in RadComboBox?

Hey,



We have a business object that implements IDataErrorInfo. The Grid validate just the visible cells. If a column that it is not visible (the user needs to scroll) has error, the entire row shows as a valid row. Just when to user scroll (horizontally) the row display as a invalid row.



see the attached screen shots.



Any idea how to fix this?



Thanks,

Mano

Hi,

I am using a Telerik tree. I want to drag a node from one parent on the tree to another. When I start dragging, I create a custom cursor with text to show what node I am dragging. When I do this, I see the cursor I want when I start dragging, but as I move my mouse, the cursor disappears and the default cursor (arrow with small square) appears. How can I disallow this cursor from overriding mine?

I know my cursor is there because if I deliberately fail to reset the cursor, I can see my custom cursor when I complete the drop.

How do I prevent the default arrow/square cursor from taking precedence over my cursor?

Thanks

PivotGrid is absolutely amazing. One issue we are running into, however, is the PivotFieldList displays all the properties of the objects in the collection. Is there a way, similar to RadGridView, to hide or prevent certain fields from appearing in the list? There is very little documentation on it. Is the only solution to create a DTO object that exposes only the properties you want?
