Problem with DataContext.

Hi, I try binding command, but it doesn't work.

private readonly EmployeeContextViewModel _ucvm;

public MainWindow() // RadWindow

{

InitializeComponent();

_ucvm = new EmployeeContextViewModel();

DataContext = _ucvm; // <<<<<<<<<

}

xaml:

<t:RadButton Content="Exit"

x:Name="LoginButton"
Command="{Binding LogoutCommand}"/>

But it works when I indicates the specific component:

public MainWindow()

{

InitializeComponent();

_ucvm = new EmployeeContextViewModel();

LoginButton.DataContext = _ucvm; // <<<<<<<<<<<<<<

}

everything works fine.
Why doesnot work in the first case and how to fix it?

RadGridView.IsBusy binding works only one time

Hi,

The IsBusy property of my RadGridView is Bound to the IsChecked property of a checkbox, so if the checkbox is checked the grid shows the loading animation, if you uncheck it the grid shows the data. The problem is that, it only works once. So if you check the chkbx loading is displayed, uncheck and data is shown. Try the second time, third, forth, etc and the loading animation does not appear anymore.

Any ideas how to make it work every time I check the checkbox?

Thanks, Bye,

Andras

Drag and Drop within RadGridView - error with DataView as ItemSource

I follow the example in the WPF Control Examples application and Telerik website http://www.telerik.com/help/wpf/raddraganddrop-within-radgridview.html . I was able to make it work with the sample "MessageViewModel" as the RadGridView.ItemSource. However, when I change the RadGridView.ItemSource to DataView (data is retreiving from DB as DataTable), I got error "Cannot insert external objects to this list." at line:

((sender

as RadGridView).ItemsSource as IList).Insert(index, draggedItem);

Does this feature work with DataView as ItemSource? How do I need to change to make it work?

Thanks

TileViewHeaderItem background

I saw this post: http://www.telerik.com/community/forums/wpf/tileview/tileview-item-header-background.aspx but it really seems overkill for such a simple property change. Is there a better(easier) way to just set the background bush for the header? For certain tiles that need to reflect a change I want to set the header background to a custom linear brush. I tried using a custom template but it only changed it for the text area and not the whole header item. I also tried the example attached in the other forum post but it didn't look correct, maybe cause we're using the metro theme?

Anyway, is there a solution I've overlooked?

Child RadGrid set SelectedItem on ViewModel MVVM

I am currently using the solution outlined this post http://blogs.telerik.com/vladimirenchev/posts/10-05-31/how-to-synchronize-your-ui-selected-items-with-your-data-context-using-mvvm-and-blend-behaviors-for-silverlight-and-wpf.aspx

to set my SelectedItem and SelectedItems from a RadGrid to a property on my viewModel (this works great by the way -thank you). What I am trying to do now is the same approach for a child grid of that same grid. I need to set SelectedDetailItem and SelectedDetailItems I believe the same approach will work but I cannot access my SelectedDetailItem and SelectedDetailItems properties (which belong to my view model) from this child grid. I simply cannot get them to bind.

I have tried a few different things such as neither of which have worked.

SelectedItem="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type UserControl}}, Path=DataContext.SelectedDetailItem}"

and

SelectedItem="{Binding SelectedDetailItem,ElementName=myViewName}"

Do you have any ideas on how to bind the SelectedItem from a child grid to a property on a view model?

Loading Panel Contents

Hi,

I'm looking at using the Docking control in my application, I have used the RadDock in a WinForms app and was wondering if this works in a similar way?

What I want to have is a RibbonBar where different views/windows can be loaded into the the RadDocking. is it possible to load views/windows this way or how should this be done.

thanks

David.

Command Behaviors

Hi All,

I am using MVVM approach, I came across http://www.telerik.com/help/wpf/scheduleview-features-loadondemand.html and understood that VisibleRangeChangedCommandProperty is provided by Telerik library itself.

I would like to know what all command behavior properties are provided by Telerik Library.

Regards,
