RadWindow.Confirm() WindowStartupLocation Issue

How can I set it to WindowStartupLocation.CenterOwner when I use RadWindow.Confirm(dialogParameters) to show the dialog?

I tried defining the Owner and the WindowStyle (in which I defined the WindowStartupLocation property to CenterOwner) but it did not work out on my computer.

I did search in Telerik documentation and this forum but did not find any clue. Did I do it correctly or is it a bug already known? How can I get around it?

Thanks in advance,
Stephen

controls in heirarchical data template - drag/tab behaviour

Hi,

I have a tree view control and in the data template of some of the nodes I have a text box to allow editing of internal settings. This works perfectly except for in two respects,

1) if you try and select text within the text box with the mouse it starts a drag of the tree item. I would like a way to have the tree ignore the drag when the text box is the clicked on control.. If I return handled from the PreviewDragStarted event then the selection of text works correctly but I am unsure of a way to distinguish at this point where the original click occurred

2) where I have more than one textbox in a data template I would like clicking 'tab' to move me to the next textbox, not the tree control itself/next control on page. I have played with the KeyboardNavigation.TabNavigation settings but not found anything that worked..

any thoughts appreciated.

                                         CanUserResizeColumns="False"
                                         CanUserSortColumns="False"

NullReferenceException when load gridview

Hello,

I have a usercontrol with radTabControl + radGridView (version:2011.1.322.40), the code structure like this:

<Grid

<telerik:RadTabControl>

<telerik:RadTabItem> <Grid /> </telerik:RadTabItem

<telerik:RadTabItem> <telerik:RadGridView ItemsSource="{Binding items1}" /> </telerik:RadTabItem>

<telerik:RadTabItem> <telerik:RadGridView ItemsSource="{Binding items2}" /> </telerik:RadTabItem>

<telerik:RadTabItem> <telerik:RadGridView ItemsSource="{Binding items3}" /> </telerik:RadTabItem>             

<telerik:RadTabItem> <telerik:RadGridView ItemsSource="{Binding items4}" /> </telerik:RadTabItem>             

</

telerik:RadTabControl

</Grid>

I use it in MainWindow, like this:

<ContentControl ContentTemplate="{StaticResource DetialsDataTemplate}"

Content="{Binding Path=SelectedDetails}" />

The SelectedDetails is a entity returning from EF that support lazyloading.

Start application, it's ok to show first tab. When I click other tab to show gridview, It raise below exception:

System.NullReferenceException: Object reference not set to an instance of an object.
