ConnectionManipulationStarted issue

1) I start dragging a connection from a node's connector. ConnectionManipulationStarted is correctly called.
2) I release the mouse outside the diagram window.
3) I then click inside the diagram window. ConnectionManipulationStarted is called again!

Clearly, this is a bug. You should capture the mouse during dragging operations. Not sure how I can work around this issue. As it is now, I end up with an orphaned connection...

Chart animation is consuming 100% CPU

Currently we are using 4-6 Radcharts on a screen in our application and when we run our application its is consuming all the CPU. When we digged in the application we found it is because of enabling animation in chart view. But when we disabled the animation in chart controls it is still using 100% of CPU.

Can you please suggest us if there is any other property or solution to disable the refreshing in charts.

Bring a specifc rad pane into focus when using RadPaneGroupRegionAdapter

Hi,
In the application we are developing we have a Raddocking control which hosts a RadSplitContainer, inside of which is a RadPaneGroup. This RadPaneGroup acts a region. RadPaneGroupRegionAdapter is used to add panes to the target (which is a RadPaneGroup in this case). Below is the adding logic that is being used. The problem is that I have to bring the first rad pane into focus. Is there a way to that. Right now whenever a new pane is added the focus shifts to the newly added pane.
Appreciate any pointers
Thanks
YK

region.Views.CollectionChanged += (s, e) =>

{

switch (e.Action)

{

case NotifyCollectionChangedAction.Add:

foreach (var i in e.NewItems)

{

if (i is RadPane)

{

(i as RadPane).CanUserClose = true;

target.Items.Add(i);

continue;

}

How to get RadDatePicker to show Error tooltip when exception is thrown in bound property

I have the following XAML and I want the error tooltip to show when I throw and exception from the ViewModel property CobDate.

It will show the error tool tip when the CobDate is invalid text, e.g. 'aaaasss' but when it is a valid date but greater then the SelectableDateEnd it will not show the error tool tip when I throw an exception from the ViewModel, it does highlight the textbox of the control with a red border but I want the error tooltip to show as well.

How can I get the error tooltip to show?

<telerik:RadDatePicker DisplayFormat ="Long"

x:Name="cobDatePicker"

Width="150"

SelectableDateStart="{Binding MinDate, Mode=OneWay}"

SelectableDateEnd="{Binding MaxDate, Mode=OneWay}"

BlackoutDates="{Binding DisabledDates, Mode=OneWay}"

ErrorTooltipContent="Invalid Date!"

AutomationProperties.AutomationId="CobDatePicker">

<telerik:RadDatePicker.SelectedDate>

<Binding Path="CobDate"

Mode="TwoWay"

ValidatesOnExceptions="False"
