Is there a property like EnableNavigation of asp.net RadCalendar for the WPF RadCalendar?
if not, how can I disable the title navigation's buttons?

thanks.

public override bool RemoveItem(FilterNode node)
{
    return base.RemoveItem(node); // This method call produces the error output below
}

System.Windows.Data Error: 40 : BindingExpression path error: 'Visibility' property not found on 'object' ''DiagramViewModel' (HashCode=33233561)'. BindingExpression:Path=Visibility; DataItem='DiagramViewModel' (HashCode=33233561); target element is 'MyChartShape' (Name=''); target property is 'Visibility' (type 'Visibility')
System.Windows.Data Error: 40 : BindingExpression path error: 'IsSelected' property not found on 'object' ''DiagramViewModel' (HashCode=33233561)'. BindingExpression:Path=IsSelected; DataItem='DiagramViewModel' (HashCode=33233561); target element is 'MyChartShape' (Name=''); target property is 'IsSelected' (type 'Boolean')

I have a shape style that does some binding:

<Style TargetType="views:MyChartShape" x:Key="MyShapeStyle">
        <Setter Property="Visibility" Value="{Binding Visibility, Mode=TwoWay}" />
        <Setter Property="IsSelected" Value="{Binding IsSelected, Mode=TwoWay}" />


Probably not critical, but I believe these errors could indicate a performance issue. The node's shape is obviously rendered when it has been removed (along with its DataContext).

I want all my RadTabItem views to be built immediately. Currently, the visual tree is built when the tab is selected:

<telerik:RadTabControl
                       IsContentPreserved="True"
                       IsSynchronizedWithCurrentItem="True"
                       SelectedIndex="{Binding CurrentTabIndex}"
                       DropDownDisplayMode="Visible" IsTabStop="True">
  <telerik:RadTabItem Header="A" IsSelected="True">
    <views:MyView1 />
  </telerik:RadTabItem>
  <telerik:RadTabItem Header="B">
    <views:MyView2 />
  </telerik:RadTabItem>
  <telerik:RadTabItem Header="C">
    <views:MyView3 />
  </telerik:RadTabItem>
</telerik:RadTabControl>

I want all tabs, "A", "B" and "C", to be created immediately. (This is essential for one very complex problem that I'm trying to solve here.)

This is probably a basic WPF question, and not specifically Telerik related, but I figured I'd ask here. I am trying to create a reusable control, right now named SectionLayout, which allows the user of the control to define "sections", with Visuals in each section. I want to render this using RadTabControl.

Basically, the consumer of the SectionLayout would be using it like this:


I've already got most of it working. SectionLayout has a "Sections" property, of type SectionCollection, that holds items of type Section. Section has Name and Content properties. Name is a string, Content is an object.

The ControlTemplate for SectionLayout currently looks like this:


So, basically I'm just making an easier interface to use a RadTabControl. So I can reuse it in other places. Though it might change from being a RadTabControl to something else in the future.

The problem I'm having is getting the original DataContext of Section.Content property to flow into the RadTabControl.ContentTemplate. The ContentTemplate is of course given the business object (Section) as it's datacontext. So, I can easily present Section.Content. However, when I do so, Section.Content begins inheriting the DataContext given to it by the ContentPresenter, which happens to be Section.Content.

How can I do this properly? I want the user to be able to use my control as he would any normal layout control: Grid, Canvas, StackPanel, whatever. But, I need to use a TabControl internally to do the layout.

Just so you know, there are multiple errors here: http://www.telerik.com/help/wpf/radchartview-axes-datetimeaxes.html (XAML and VB).

Hi,

I'm using RadPivotGrid with Column Group:

            <pivot:LocalDataSourceProvider.ColumnGroupDescriptions>
                <pivot:PropertyGroupDescription PropertyName="Periodo" CustomName="Período" SortOrder="Descending" />
            </pivot:LocalDataSourceProvider.ColumnGroupDescriptions>
As the attachement image shows, I've put the total before column groups. It's a native control feature.

Now I want:

1 - That totals  cells have lines like group cells;
2 - Alternating backgroung color for group cells. Example: group A cells background diferent from group B cells background.

How can I achieve this?

Trying to bind to a collection of objects that encapsulate parameters:
these are read dynamically at runtime, and each parameter could be of a different type. The collection (array) is then contained in another class.
If i bind to an instance of the 'parent' class the parameter collection shows up via the colleciton editor ui, however, the values are not updated on edit.
Since we are not really interested in the parent object, I have tried binding to the collection directly, but then the only properties I get are the ones from the collection object itself, like Count.
What am I missing here, what do I need to define/override for the grid to work with these?
Pointers to example code would be excellent! :)

I have done grouping in the Telerik Gridview,My task is to Alter the header of the Group item at the run time , So i have implemented the below Code while clicking on the Expander i could able to get the content Nothing is displayed. 
Please help me on this

Howdy. I know this component is fairly new... but is there anyway to set the Add and Delete commands? Basically, they need to do things in my view model. As far as I can tell, they seem currently hard coded to actually add or remove items from the underlying collection.

I have a custom style for my connections. I set the target cap type as follows:
<Setter Property="TargetCapType" Value="Arrow1Filled" />

The result is an arrow pointing in the wrong direction, which is kind of ugly. See attached image!

How can I fix this?
