Hi,

Hi,

I need an urgent help in tree-view control. I am not able to attach the  sample project which has the problem i am facing.
when i am binding a boolean property to checkstate using code behind and converter as suggested the parent node is behaving in a crazy manner.
If i check 2 out of 3 children under a parent node then parent node is showing state of checkbox as intermediate. But if i check the 3rd child also the state of parent node remains intermediate which should get changed to on(checked) or if i uncheck one of the child node then the parent node state changes to off(unchecked) which should remain in intermediate.
I think there is some bug in the control. but if there is some trick which can fix this will help me a lot. I tried to create a support ticket also but its showing some server error.
Thanks for any help.

thanks,
Anil

What control is being used for the Sales Representatives list down the left side of the Sales Dashboard demo? Is the code for this demo available for download anywhere?

Thanks.

Hello,

I have a RadRibbonSplitButton, whose DropDown Content is set to a plain UserControl housing only a single ListBox and a single 'Accept' button. This ListBox has some drag/drop code written to allow drag/drop of a row to another position within the same ListBox. Essentially, just repositioning a row within the ListBox to another position. When 'Accept' is pushed, I use the order of the rows in logic elsewhere in the app. If the context menu is clicked out of it disappears correctly, and if the user never clicks outside of the control, they are able to effectively select listbox items as they like, and drag/drop the listbox items to whatever positions they desire, all with the RadRibbonSplitButton drop down staying open until the 'Accept' button is pressed or the user clicks somewhere besides the drop down.

My problem, is that in WPF, anytime I clicked within the listbox, the RadRibbonSplitButton closes, (I believe a routed event may be getting handled here from the ListBoxItem Selection, and RadRibbonSplitButton handles that and closes the drop down) I set 'KeepOpen' to true, to get around this in WPF.

But whenever a Drag is initiated from one of these ListBox Items, the drag cue is displayed correctly and hovers while I drag, but the RadRibbonSplitButton drop down closes immediately. (So there is no List Box showing for me to reposition the ListBox Item being dragged)

I noticed this thread http://www.telerik.com/community/forums/wpf/draganddrop/drag-and-drop-between-a-window-and-a-popup.aspx, which notes that you cannot drag/drop between pop ups, but in my scenario I am just dragging/dropping within a single RadRibbonSplitButton drop down...

Do you have any suggestions that might help me achieve the functionality I am after, having the RadRibbonSplitButton drop down remain open until the 'Accept' button is pressed, or until the user clicks outside of the drop down. Not closing immediately, when a drag is initiated from within the drop down's ListBox?

Thanks for any help you can give!

I started with the example with the Leages and Division (as example for data binding from the Demo) and added a tristate checkbox to the treeview and a "bool?" in each class. Initially all items are set to "true".

As described here I added the CheckStateConverter class which also handles the Indeterminate state.


The data binding works fine, but the thing I can't understand: If I expand "League A" and "Division A" and uncheck "Team I",  "League A" and "Division A" also switch to "unchecked" instead of "indeterminate". If I uncheck "League A" and check it again the whole tree behaves correctly. What is wrong in my example?

Thanks in advance!

Hi there,

I am getting a serious NullReferenceException (haven't managed to catch it by exceptions and it crashes my client), and it goes something like this:

   at Telerik.Windows.Controls.Map.BingMapProvider.InitializeProvider() in c:\Builds\WPF_Scrum\Release_WPF\Sources\Development\Controls\DataVisualization\Map\Providers\BingMapProvider.cs:line 542
   at Telerik.Windows.Controls.Map.BingMapProvider.ImageryService_GetImageryMetadataCompleted(Object sender, GetImageryMetadataCompletedEventArgs e) in c:\Builds\WPF_Scrum\Release_WPF\Sources\Development\Controls\DataVisualization\Map\Providers\BingMapProvider.cs:line 499
   at Telerik.Windows.Controls.Map.VEWPFImageryService.ImageryServiceClient.OnGetImageryMetadataCompleted(Object state) in c:\Builds\WPF_Scrum\Release_WPF\Sources\Development\Controls\DataVisualization\Service References\VEWPFImageryService\Reference.cs:line 2106
   at System.Windows.Threading.ExceptionWrapper.InternalRealCall(Delegate callback, Object args, Boolean isSingleParameter)
   at System.Windows.Threading.ExceptionWrapper.TryCatchWhen(Object source, Delegate callback, Object args, Boolean isSingleParameter, Delegate catchHandler)

It seems to be happening at random, so I can't pin it down.  Is there any way I can solve this please?

Thanks,
Simon.
