I'm trying to bind RadGridView SelectedItems property to a property on my ViewModel using the custom Behavior approach mentioned in the blog post, but it's not working.

I remember some folks having trouble with it when setting the dataContext at runtime rather than as a static resource. I'm using Prism's Dependency Injection to inject the viewModel into a property on the View. I can see that my ObservableCollection on my viewModel is being populated, but it's not showing up as selected items on my grid.

I need help getting this to work properly.

I'm trying to implement dragging from a ListBox onto a ScheduleView, using DragAndDropManager.  I'm as far as the DropInfo handler on the view where the ScheduleView resides running, and am successfully getting the information that I want from the ListBox.  What I can't figure out is how to find out which slot I am trying to drop into.  DragDropEventArgs.Options.CurrentDragPoint would seem a promising way to this information, and the demos show how to so this for the old Scheduler control, but ScheduleView appears to operate differently.  The only other piece of information that I can find suggests that DefaultDragDropBehavior.ValidateExternalDrag "could be used to add the appointments from external source".

Is there a simple example available demonstrating how to drag from an external non-ScheduleView source onto a specific slot within a ScheduldeView in order to create a new appointment based on the dragged-in object?  If not, would it at least be possible to provide some pointers as to how I can achieve this?


Thanks

I'm porting from DataGridView to RadGridView and I am currently having problems with the validation logic in the RadGridView. I want to add the new item to the ViewModel collection directly after "Click here to add new item" has been invoked, but since the item has validation errors exposed through IDataErrorInfo, the RadGridView wont commit. How can I alter the behaviour of the RadGridView to commit new rows to the datasource directly after creation of a new row?

How can I Wrap a Cell content in a Grid while Resizing the column. If a size of a colum goes smaller the cell text must be wrap in downward / Upward direction , So that whole text in a cell will be shown.

Hi,

Is there any way to drag group separator to expand width of some specific groups important for end user?

Scenary: The application have three view using outlookbar control(outlookbar control doesn´t belong to telerick). Each outlookbar button load a wpf
project of dynamic way using reflexion.
When switch views appears the error (the render the view)
We had debugging and separating the controls. when the docking control was changed by a grid control  the error not appeared.

Platform is:

Please help me out.

Hi,

Hope someone can help me with this issue that I'm facing right now.

I'm trying to implement some behaviours in calculated columns (which are not Expression columns by the way). The goal is to have the last column value returned by the business layer based in the other column values. 

I'm actually setting the DataContext as a DataView (DataTable.DefaultView), but when I try to programmatically make any change to the DataContext, the last column value doesn't actually refresh (visually) until I change to another row. 

I thought that using DefaultView, and since it implements the INotifyPropertyChanged, the row being edited would be refreshed automatically. But in fact that doesn't happen in this case.

Converters and Expression columns are not exactly an option (at least I think so), since I send the grid's DataContext back to my Business layer where I set the last column value for each row.

Help would be extremely appreciated.

Hi,

simple questions...

1) are there any limitations on the sand chart on number of layers it can have?
2) Can we have a context menu on the bar chart or sand chart menu?
3) On the sand chart, can we have a drill down chart on mouse hover?
4) can sub charts (on mouse hover to chart series) have drilldown?

Thanks,
