_CreateDelegate not found

I get the following error when I try creating a custom class and wire up to an event in the CellTemplate of a RadGridView. Can anyone explain why this is? I know it is not my code because when I use the custom class in the host page directly, it works.

'MyHyperlink_OnClick' value cannot be assigned to property 'OnClick' of object 'WpfBrowserApplication3.MyHyperlink'. Method 'WpfBrowserApplication3.Page1._CreateDelegate' not found. Error at object 'WpfBrowserApplication3.MyHyperlink' in markup file 'WpfBrowserApplication3;component/page1.xaml' Line 14 Position 24.

I would attache a sample, but the site is not allowing me. Thanks.

Grid cells are getting disabled for grid with few columns freezed

Hi,

I have a grid with 15-20 columns generated dynamically. First 2 columns are freezed. Third column is disabled. When we try to scroll the grid horizontally(with first two columns freezed), some of the cells are getting disabled. If we keep on scrolling grid horizontally(to left and right), the columns are getting enabled/disabled. The behaviour is not uniform too. Sometimes, cells are not getting disabled.

Please help.

Thanks and Regards,
Norbert John

Item locations not updating

I'm programmatically changing the location of items that are data bound to the map but they don't actually update their positions visually on the map until I pan the map with the mouse. Is there some way to force the map to refresh automatically?

Thanks!
