If the user manually enters "0" in the date textbox and lost focus from date picker , app crashes.
Its seems to crash only with "0"...it does allow the "1" or "2"..or even allows the user to select a NE entry date from the calendar menu but manually delete almost the whole of it.
Error : Year, Month, and Day parameters describe an un-representable DateTime.
'
You can check in Telerik C# sample exe also. It simply crash when you enter '0' in datepicker and lost focus.
Please advice me how to solve or atleast how to stop manual entry in that control asap. We have release soon.

What are the new classes I can used alternatively? I cast a Record to a DataRecord to access its Data property currently.
SelectedRecords and its CollectionChanged event are gone...

I'm getting strange results with the gridview when I maximize my window and the Gridview has data. I can't figure out why it's happening (because sometimes maximizing the window works just fine and sometimes it doesn't). Here's the stack trace:

Hi Guys
I am trying to bind my chart to a ObservableCollection of ObservableCollections is this possible?
I have worked look at ms-help://telerik.windows.controls/telerik.windows.controls.charting/data-binding-series-mappings.html but no joy. Do you have a sample of this in VB ?

Hi,
is there a possibility to select or to doubleclick a row only by clicking on the RowIndicator?
I need an event to open a new Window in a RadGridView.
The double click event of the RadGridView works, but if you try to change a value of a column and if you are clicking too fast, you will hit the double click event.
