Hello,

Can I change ScheduleView  groupby value from the code?
I need to change grouping on the fly.
Is there any equivalent to the Scheduler.GroupBy property?


Thank you,
Oksana

Hi,

Another databinding question for PanelBar... I have ViewModel with two properties Header (string) and View (UserControl)

I want to bind "Header" property to the Header of RadPanelBarItem, and...
"View" property on my VM to the "content" area of the RadPanelBarItem.

For each ViewModel, there is only ONE Header and ONE View property.

I see from examples something like

<RadPanelBarItem>
  <RadPanelBarItem.Header>
      HEADER TEXT GOES HERE
  </RadPanelBarItem.Header>
 
   CONTENT GOES HERE
</RadPanelBarItem>

But I can not get this working with databindings... there are HierarchicalDataTemplate examples, but that does not compute for me, mostly because HierarchicalDataTemplate ItemsSource="{Binding View}", since View in my case is a singel property, not collection; and I am not sure if HierarchicalDataTemplate would work for a (singel value) property as a source.

This is what I got on my own...

<telerik:RadPanelBar ItemsSource="{Binding ...}">
   <telerik:RadPanelBar.ItemTemplate>
    <HierarchicalDataTemplate ItemsSource="{Binding View}">
     <TextBlock Text="{Binding Header}" />
     <HierarchicalDataTemplate.ItemTemplate>
      <DataTemplate>
       <ContentControl Content="{Binding View}" />
      </DataTemplate>
     </HierarchicalDataTemplate.ItemTemplate>
    </HierarchicalDataTemplate>
   </telerik:RadPanelBar.ItemTemplate>
  </telerik:RadPanelBar>

When trying to use IsVirtualizing we are running into an issue with checkboxes not in the initial view are set incorrectly on data load. We are not binding to IsChecked property but are binding to the CheckState property.

The following is used to define the RadTreeViewItems:


The RadTreeView includes the virtualization settings:


Does it look like the xaml is wrong?  If not, is there a work-around or a fix for this?

Without the virtualization, the RadTreeView is unacceptably slow on loading a list of just 7500 root level items.

Thanks,

T.

Hi there,

I did add the RadWindow class to my project and I found an exception occuring somehow in a random fashion.

There are serveral RadWindows in my application and they do work fine. But when I do add the ShowDialog of one of the RadWindows to the SelectionChanged event of a RadTreeView on my form, I do receive the exception shown below when closing the window again. This exception does not always show up, it only occures in a somehow random way. As you can see, there seems to be a problem in the OnThumbDragStarted event handler or one of the methods it is using.

I'm using the Q1 2011 version of the telerik libraries as I did update the version when I was working on this issue, but the update did not solve the problem.

Do you guys have an idea why I do receive this exception?

Hi,

I have an issue with the WPF RadDocking Control (Version Q3 2010). 

I implement the RadDocking on my Window, some RadPane contains Usercontrol.

Here's the XAML :

My two usercontrols (TocControl and OverviewControl) have some ActiveX controls nested inside. When the pane is docked it displays perfectly but as soon as I pin or make it floating it doesn't display anymore.

Do you know a workaround to fix this issue ? 

Thank you and I wish you a great day.

Hello,

 

I have a class “Priority” which derives from the Category class and fires PropertyChanged when (New) CategoryBrush changes.

I assign the collection of Priority objects to the CategoriesSource property of the ScheduleView control.

The Edit window loads the list fine, but when the brush color of the Category aka Priority changes in the configuration window - the Edit window doesn’t reflect the change. Other controls bound to the CategoryBrush property of the same collection change the color but not the ScheduleView.

Can you see why?

 

Thank you.

Hi,
  I have just started my adventure with WPF. I have heard that it is dedicated for graphical applications. I'm interested in creating a control that handles linear chart and transform it into chart in a circle. I just wonder if there is some easy way to do that?

Thank you in advance for any reply.
