In the method signature for the event handler for the event 'Edited' there are the following parameters: ( object sender, RadTreeViewItemEditedEventArgs e ).

How can I get the RadTreeViewItem that is being edited? e.OriginalSource returns an 'EditableHeaderedItemsControl' and sender returns the RadTreeView. Is there something I am missing?

Thank you.

EDIT:

OK, I was able to cast e.OriginalSource to RadTreeViewItem. The problem that I am encountering is that I want to delete the node if its header is empty. So inside the Edited event handler I have the following code:


I get the following null exception:

I have a project that I'm deving from scratch.

SQL database
wpf and web
stock/inventory  - ordering, tracking

anybody interested in helping me out..  

I want to initiate sort on the grid from code.  I am not having success.

This is what I've tried:

gvDocumentListing.Columns[4].SortingState = Telerik.Windows.Controls.SortingState.Descending;

 

gvDocumentListing.Rebind();

This does not work.  I saw in an earlier post that some one called Columns.Reset().    This method appears to have been removed.

Good morning

I am developing an application WPF touchscreen, I need to have scrolling programatically.
The example 117850_117835 if it works to me, but with Q3 displays error in the following line.

Panel = Me.RadGridView1.ItemsControl.VirtualizingPanel

'temsControl' is not a member of 'Telerik.Windows.Controls.RadGridView'
As it works in the Q3

Thanks

Is there a way to determine the actual position of a RadTileViewItem in a RadTileView? Something like
RadTileView.GetPosition(RadTileViewItem item, out int row, out int column)?

Thanks,

Hi,

I've created a treeview which has the TriStateMode enabled and defined a callback function when an item were checked/unchecked.

My problem is that I get notified multiple times if a subitem was checked. The first notification is for the top element, and the next notification is for the top level's child element and so on... The last notification is the checked item itself.

Is there a way to determine the item which was checked?

Thanks
Dieter

Hello :)
Exists pt-br resource for WPF controls?

I have a gridview, using version 2009.3.1208.35 and MVVM. Style and visibility is applied like the following:

Hello,

The column of my grid is set to SizeToContent, which of course causes my column size to increase to the size of the lengthiest data in the column, which is great. When the row is removed, however, the column remains at that extended size. I would like to be able to have my column automatically "snap back" to the next lengthiest bit of data remaining in the grid, but have been unable to find a way to accomplish this with any of the existing properties. Is there a way to accomplish this kind of behaviour I'm missing?

Thanks,

Dave

I have a RadTabControl with a Custom ContentTemplate. It works fine, and displays the content as I'd expect when first viewing the tab. However, when changing from one tab, back to the original tab, I find that the data inside the content presenter is no longer being displayed. It appears as if the DataContext or ItemsSource binding is no longer being applied as I'd expect.

Below is a short expample which should illustrade what I'm seeing. I'm using MVVM, and the ClosedOrderCol in the code snippet below is an ObservableCollection on the ViewModel.

Any help would be appreciated.
