Drag Selection Issue w/ GridView

There's a bug w/ Q1 2010 (not sure about latest internal build) with SelectionMode = Extended in the GridView. If you try to drag-select with your mouse it doesn't get the selection right (it starts selecting rows far below what you really are trying to select).

You can reproduce this error in your demo app in the "Selection" demo for GridView by changing Selection Mode to Extended. Do that, click a cell and drag your mouse down.

ContainerFromItemRecursive and IsSelected

We have a treeView with data populated programmatically using:

    
            ObservableCollection<MyInterface> items = new ObservableCollection<MyInterface>(); 
        
            this.myTreeView.ItemsSource = items;

Now we would like to select item from different "external" events on this way:

    
            RadTreeViewItem rtvi = this.myTreeView.ContainerFromItemRecursive(currentItem); 
        
            rtvi.IsSelected = true;

Actually the rtvi object seems to be found and correct....but we don't see any changes on the controls.

Any way to do it with that approach?
Thanxs.

Child Grid Not Displaying Columns When ShowColumnFooters set to true

Hello,

Just updated my controls to 2010.1.402.1. We were going off of the GridView/Hierarchy/CustomHierarchy example. in the DataLoading method if we set ShowColumnFooters = true then none of the columns are displayed. We did try it with a DataTemplate in xaml instead and that seemed to work just fine. Any ideas on how to display the column footers without setting it all up in xaml?

GridView ChildTableDefinition Issue

Hi Telerik Team,

I'm binding the Grid with different Item Sources some of which contains Child Table Definition and some don't.

When switching between the two item sources, the grid view still displays a blank column for the results which does not contains a child table definition. I cleared the Child Table definition before binding the item source and it only hide the column in the item rows not in the header. Please see the attached snapshot on this. I even tried removing the child table definition before binding the non-child definition item source but of no use.

cheers...

RadMenuItem IsChecked

I am trying to bind a IsChecked property of a RadMenuItem and does not fire the set event on my ViewModel property. When I had it set to a regular MenuItem, this was working. Is this not supported in the RadMenuItem?

DOES NOT WORK:

    
            <telerikNavigation:RadMenuItem x:Name="ShowSummary" 
        
            Header="Value Summary" 
        
            IsChecked="{Binding Path=IsSummaryChecked}" 
        
            IsCheckable="True" />

WORKS:

    
            <telerikNavigation:RadMenuItem x:Name="ShowSummary" 
        
            Header="Value Summary" 
        
            IsChecked="{Binding Path=IsSummaryChecked}" 
        
            IsCheckable="True" />

How do I turn off the selected item on load?

Hello,

We were using the Q3 2009 release and recently upgraded to the Q1 2010 SP1 release. It appears the first row in the RadGridView is now automatically selected. How can I set the grid to appear as nothing is selected when the application loads?

Pie chart default animation when increase values

Hi,

I have an ObservableCollection of objects (which implements INotifyPropertyChanging), binded to a PieChart.
If I increase/decrease values in my objects (responding to some input controls), Pie shouldn't reflect that by increasing corespondend slices (perhaps animating them)?
I can't get a simple example like this working and I want to know what's the default behaviour.

Thanks a lot!
