I have a an MVVM app where a page has a gridview bound to an entitiyframeworkdatasource.  The data loads as soon as the page loads and takes a while... so it blocks the UI thread.  Is there a way to prevent this?  I tried using another thread but couldn't get it to work right.

Also, how would I go about saving and undoing changes?  I created a button to save where I just call SaveChanges on the context.. and that works... But if I revert all changed entities in the context, the grid doesn't update the rows.

Are the 3d charting features depreciated?

 http://docs.telerik.com/devtools/wpf/controls/radchart/features/chart-types/3D-charts

The above link is all the documentation I can find for 3d charting features. 

Thanks

Hi guys,

 we're using RadGrid with EntityCollection bounded ItemsSource.

One column of the grid is bound to a child entity of that collection. I am getting an error, while click on the header of that column (sorting).

Is there a workaround?

Der Typ "KlientBankEntityCollection" besitzt keine Eigenschaft mit dem Namen "Bank.BankName", weshalb die Datensammlung nicht sortiert werden kann. in PresentationFramework (type xyz has no property named xyz2, so data can not be sorted)

Hi

I'm trying to create a custom shape container by restyling RadDiagramContainerShape, but I'm running into a few problems relating to layout. It appears that RadDiagramContainerShape forces a specific padding between the edge and the children and moves the container if the children touch the border. It also resizes to accommodate the children.

Is there any way to hide the header, force it to not resize and allow the children to be positioned right up against the edges?

I'm trying to create a UI design tool and need a container that will allow the contained children to be position anywhere in the container.

Thanks

Hello,

I would like to prevent user from using select all Ctrl+A.

I tryed to ovveride this behavior through command binding but it didn't work 

 Thank you .

I just upgraded to 2015.1.608.45 and I'm seeing tons of "errors" when a xaml file is opened.  These are not real errors because I can compile and run the code.  But it slows down development tremendously because the time it takes to save change to xaml is enough to make me want to take a nap!

What can I do to take care of this?

Hello,

I have two questions about the RadDatePicker.

I have a requirement that the enter-key should be used to select the date and move the focus from the DatePicker to the next control.

At the moment when I hit enter when a date is selected the calendar will close and the focus goes back to the textbox.

How can I move the focus to the next control immediately after I select the date, so with one-enter press the date is selected and focus moves to the next control?

I tried to handle the KeyDown event and the DropDownClosed event, in the event handler I call MoveFocus to the next field, but in both cases the focus remains in the DatePicker?

 My second question, whats the best way to change the size of the calendar, I want it to have a bigger size and bigger font (wider then the DatePicker textbox to which it belongs). How can I accomplish this, without changing the width of the textbox?

Regards,

Marcel

Hi, 

 I added couple expanders inside a stackPanel. But my stackPanel takes up full height into consideration, irrespective of Expander's state. Kindly help me figure out what I missed on Expander's setting.

Is it possible to just scroll the time slots (vertical scrolling) and keep the Group headers stay.

 Thanks
