Rotate X-Axis Label For 3D Chart

Hi,

Is there a way to rotate the 3D chart x-axis labels?

This works for a 2D chart, but does not rotate the 3D charts...

chart.DefaultView.ChartArea.AxisX.LabelRotationAngle = 90;

Thanks,
Pauly

Subclassing RadTreeViewItem

    
                public class Subclass : RadTreeViewItem 
        
                { 
        
                }

    
            <telerik:RadTreeView> 
        
                    <local:Subclass Header="Group -1"/> 
        
            </telerik:RadTreeView>

Everything compiles, runs, I just see no Item in the TreeView...I shouldn't have to override the metadata for the DefaultStyleKey should I; it should just inherit by default.

RowEditEnded bug

Not sure if this is supposed to happen but....

I have set the validation mode to "row" and created the even handler for grdviewRas_RowEditEnded

everything seems fine as I create a new row and begin entering data however one of the columns is a date. When I click on the date picker and select a date the RowEditEnded event fire even though I still need to enter more data.

Is this something I am doing wrong?

Cheers,
Kevin.

Expand empty PanelBarItem

Hi

I bound a RadPanelBar to a object structure like this:

    
            - MyObject1.1 
        
                - MyObject2.1 
        
                - MyObject2.2 
        
            - MyObject1.2 
        
            - MyObject1.3 
        
                - MyObject2.3 
        
                - MyObject2.4

it seems now, that empty PanelBarItems does not expand out of the box. so if I click on the header of the item "MyObject1.2" it does not expand nor the currently expanded one does collapse. I already figured out that i can catch the event "Selected" of the RadPanelBar to expand the item by myself:

    
            private void RadPanelBar_Selected(object sender, RadRoutedEventArgs e) { 
        
                RadPanelBarItem selItem = e.OriginalSource as RadPanelBarItem; 
        
                if (selItem.Items.Count == 0) 
        
                    selItem.IsExpanded = true; 
        
            }

this works quite well, except that I am not able to collapse the last selected item. So my questions are:
- is there a better way to expand empty items?
- how can i collapse the items manually?

thanks
Simon

UI Automation

Do the WPF controls support UI Automation? I see mention of it for Silverlight, but not WPF. Thanks.

[Solved] RadCalendar should disappear on MouseUp, not MouseDown

I have a situation where I have a RadDatePicker situated above another control. I click on the Calendar button to display the Calendar, select a date, and then the MouseUp event is triggered on the control that is under the Calendar. This is because the Calendar disappears on MouseDown rather than MouseUp. Is there a way to work around this issue? If not, can this be considered a feature request?

[Solved] Selecting an item in a collapsed group programmatically

Hi,

If I try to select an item programmatically, and that item is in a collapsed group, an IndexOutOfRange exception is thrown. Is there any other way of avoiding this besides expanding all groups?

Thanks in advance!
