TreeView tool tip

Hi,

I have noticed that (particularly under resource intense processes) that the tool tip can appear at the top left of my application rather than on the node hovered over.

Is there a fix for this

thanks

Adding reference to chart controls breaks intellisense in XAML

Trying to familiarize myself with the 4.5 WPF chart controls, but I found that adding a reference to Telerik.Windows.Controls.Charting breaks all intellisense in XAML. Same appears to go for Controls.Chart, and Controls.Data.

I'm using a build that seems to have the .DLLs dated Oct 17th.

Changing MouseOver/Selected slot brushes

Hi,
I am working on a month view in the ScheduleView control, and I've been trying to find a way to change the brushes of the slots (ie the TimeRulerMonthViewItem) when they are hovered over or selected.
Another related issue is srtetching that selection/hover border to fill the entire slot - instead of just under the GoToDayButton I want it to also show behind the button (the button is transparent of course).
Is there a way to apply this style changes?

Please see attached photo (hope it's comprehensible).

Thanks,
Nadav.

[Solved] How to get Member, Operator and Value from Filter events

Hi Telerik Team,
Almost in all of your examples of Filtering concepts I found, you directly given the Member, Operator and Value for FilterDescriptor. But, I wish to give that values dynamically. How to achieve it? I'll be very thankful to you if suggests any good idea for this..

Private

Sub Me_Filtering(ByVal source As Object, ByVal e As GridViewFilteringEventArgs) Handles Me.Filtering

I tried to get this from e, but couldn't get.

Private

Sub Me_Sorting(ByVal source As Object, ByVal e As GridViewSortingEventArgs) Handles Me.Sorting

But, I can get Member, SortingState from e in Sorting events.

Please Help..
