Hi,

I have a RadTreeView bound to my datasource and everything is working fine, however, I am having trouble when adding a new object to the underlying databound collection, your documentation does not seem to cover this scenario in depth. What I would like to achieve is this:-

Each time the user right clicks on a treeviewitem a dynamic context menu is built and displayed. (it has to be a dynamic context menu because each node represents a particular business event)

On selection of a menu item , a new node is added to the tree , brought into focus and in edit mode.

I require a reference to the treeviewitem each time the user selects a node (I am a bit confused why the SelectionChanged event does not pass me back a reference to the treeviewitem)

    
                <DockPanel x:Name="dp" LastChildFill="True" > 
        
                    <DockPanel.Resources> 
        
                       <ContextMenu x:Key="contextMenu">

Column header width

Hi,

I currently have 2 issues on the width of a column.

1) if you change the size of the 1st column by dragging the separator and 'hide' the column, you can't get it back. All the other columns can be restored, but the 1st isn't restorable. This only happens when the user can't freeze columns.

2) It seems like the auto-size functionality of the columns only works 1 time. Normally if you resize a column and double-click on the separator, the column will auto-size to the right size. Currently, this doesn't appear to work, with any of the ColumnsWidthMode values.

Filter GridView

I download a project from this forum
it was ok
but when I copy the code to my project it fail

this is the code

var

masterFilter = (CompositeFilterDescription)(this.RadGridView1.FilterDescription);

var subjectFilter = (FieldFilterDescription)masterFilter.FilterDescriptions[0];

subjectFilter.Values.Add(

"Cats");

this is the error
Error 1 'Telerik.Windows.Data.FieldFilterDescription' does not contain a definition for 'Values' and no extension method 'Values' accepting a first argument of type 'Telerik.Windows.Data.FieldFilterDescription' could be found (are you missing a using directive or an assembly reference?)
