RadDocking PreviewClose Event, how do you get the Pane control which is closing?

Hi,

I'm using the RadDocking control and added a handler for PreviewClose to be notified when a RadPane closed. This is firing ok, however I'm not quite sure how to get the RadPane control more importantly the Name of the control which is being destroyed, I need this to clean up my data storage behind the scenes.

Please can some one provide me with an example or point me in the right direction?

Kind regards
Neil

telerik.windows.examples assembly not found

Downloaded and installed the Radcontrols for WPF and I want to run the examples locally (so I can disect the code <hehe>) but I'm having a problem with not finding the telerik.windows.examples assembly.

I've gone through all the telerik assemblies and I simply can't find one that remotely seems to be the telerik.windows.examples one.

Thanks

Resizing between two RadDocking Controls and Real Closing of Panes

hi guys,

i've been trying out the RadDock control via "RadControls_for_WPF_2009_3_1314_TRIAL.msi" for the past two and something weeks for my company, we're looking to buy docking capabilities to our WPF .Net 3.5 app.

it's looks great, feels great, and easy to program with - NICE work you guys.

some things that i need some help with trying the control:

my basic WPF app - in XAML: i've put a dock panel in a window inside a grid. added an expander (RadExpander of course) docked to the right side. added two RadDock controls one of them docked to the Top and one to the Bottom.

1. i had to set the DockPanel.Dock attached property on both RadDock controls -

when i set only one to dock to the Top and nothing on the other one - the RadDock didn't show... although it should make the second RadDock fill the available space in the panel, no?

2. i want to be able to resize each of the RadDock controls, 'cause now i can't really control their size as a user on run time. i thought about putting them into a grid with splitter between them, but is that the best way?

3. in that same example - when i drag a pane from the top-docked RadDock control - moving it downwards makes it "hide" behind the bottom-docked RadDock control (that's normal i guess?) but dragging it to the right i can move it, still floated, on top of the RadExpander, it's looks odd 'cause it's hiding behind the bottom-docked RadDock control but on top of the RadExpander,

any ideas of making it look better?

4. the Close button on a pane makes it Hidden (that's great!) but in our app we have the need sometimes to create a lot of floated panes that the user can close and open new ones, i wanna know if there is a way to "really" close the pane i.e. get ride of it, dispose it - whatever, my fear is from large memory usage because some of these panes store lots of data and controls in them,

i'm working on trying big quantities of data and control in panes to see what happens - thought about asking first how to deal with it.

hope i was able to explain myself clearly,

thank you so much in advance.

Lior.

SortDescriptor error in Expression Blend 3

I have a RadGridView bound to a generic ObservableCollection of a class I use in my application.
The class has a public property called ID (int)

I created a sort descriptor to make sure the data is sorted using the ID field
Code:
<Telerik:RadGridView.SortDescriptors>
<Telerik_Windows_Data:SortDescriptor Member="ID" SortDirection="Descending"/>
</Telerik:RadGridView.SortDescriptors>

While working at run-time the code generates an Expression Blend 3 error:
"Invalid property or field - 'ID' for type Object"

I'd appreciate any input on why.

Optimizing RadGridView

I'm looking for any guidelines for optimization of the RadGridView. Specifically, I'd like to know if such documentation exists which specifies grid options which might be "performance-heavy". Even though you can load millions of rows into the grid, you still see [the familiar WPF] large spikes in CPU. I'm interested in turning off all non-essential functions to get more performance out of the grid, and am looking for features or settings which ppl. feel helped the overall performance. So far I turned off sorting, highlighting/selection, etc. Each helps / just looking for a general set of principles to really optimize perf.

Show binded SelectedItem

Hello,

I'm using the WPF Carousel in my application and bind the ItemsSource und SelectedItem properties. But when the carousel is loaded, the SelectedItem is not the one the carousel shows in front of it. I've looked at the SelectedItem property in the Loaded event and it was set correctly. I've tried many different ways to achive this:

foreach (CarouselItem item in carousel.Panel.Children)
{
   if (item.Item == carousel.SelectedItem)
   {
      item.BringIntoView();
   }
}

carousel.SetIsSelected(carousel.SelectedItem, true);
carousel.SetIsCurrent(carousel.SelectedItem, true);
this.carousel.BringDataItemIntoView(carousel.SelectedItem);

carousel.CurrentItem = carousel.SelectedItem;

But none of them worked. How can I achieve it?
