Hi,

in my application, I'm using Telerik theme "Office_BlueTheme" and the control HeaderedContentControl doesn't seem to be affected by the theme I choose, I mean, the header of the control stay gray instead of having a kind of blue like other Telerik controls I used.

Thank's

Right, I have a list box to the left, and a schedule view to the right. On the schedule view I have included resources, by which I group. When I drag from the list to the schedule view, I can only drop onto the first group. When I attempt to drag an appointment already on the schedule view to another group on the schedule view, it won't allow it.

I have implemented a custom drag drop behaviour class:

			}
 
			ContentControl cue = new ContentControl();
			cue.Content = panel;
 
			return cue;
		}
	}
}

And I have the following xaml definitions for the listbox and schedule view:

                                 EditAppointmentDialogStyle="{StaticResource EditAppointmentDialogStyle}"
                                 Grid.Column="1"

                    <GradientStop Color="#FF6E6E6E" />

            </ListBox.Background>
        </ListBox>

I could really do with cracking this problem ASAP as I have deadlines to meet very soon, I really really appreciate any help you can give.

Hi, can someone tell me how (or maybe it's not possible) to center the content inside the RadRibbonButton? The text and image I set is always left justified for some reason. For each button I add to the tab (or group) I have a large image and text. I would like to center this if possible. HorizontalContentAlignment doesn't seem to do anything.

Example:

Or

Hello,

Practically identical to a thread opened recently for the Silverlight control...

Rather than have the zoom controller on the Image Editor UI default to a value of "100%," I'd like to have the option to default its value to "Auto." Is this property currently implemented and I just don't see it?

Thank you,
Kyle

I specified the SelectionBoxTemplate on my ComboBox, but its being ignored. My code is:

Hi Telerik,

I am very new to wpf telerik controls. I am using richtextbox. I learn how to add customize text from code behind. But how can I add customize text from ViewModel.

Hi,

Is it possible to have a RadPane automatically fit to the size of the control its in? I'm guessing this would need to be done at the RadSplitContainer level. Any suggestions?

Thanks!

Hi there,

I'm having difficulty figuring out how to bind my data ( ObservableCollection(of) ) and to display it as a hierarchy using vb.

I have the following example data, similar to your C# example I saw in another post called Treelistview-Self-Hierarchy.


** Please note again that the above is an ObservableCollection(Of ) list.

I have the following XAML List view.


I then set the ItemsSource in VB:


This displays all the information correctly in grid. However I need to group the items according to it's hierarchy.How can I achieve this with the minimal of fuss?
** Please note I am a newbie! **

Out of interest, the hierachy in my SQL 2008 database uses the new hierarchyid data type. Can the TreeListView use the hierarchyid data directly to generate the tree nodes?

Hello, I'm having trouble figuring out how to add a button dynamically in a radgridview.

I'm porting over working code that used the stock WPF DataGrid control.  This is the method I *used* to use:

  private DataGridTemplateColumn GetButtonColumn(IListPropertyInfo i)
       {
           var buttonTemplate = new FrameworkElementFactory(typeof(Button));          
           buttonTemplate.SetBinding(Button.ContentProperty, new Binding(i.columnName));
           buttonTemplate.SetValue(Button.StyleProperty, DefaultStyles.GridColumnButtonStyle); 

           buttonTemplate.AddHandler(
              Button.ClickEvent,
              new RoutedEventHandler((o, e) => HandleColumnButtonClick(o, e))
          );

           DataGridTemplateColumn c = new DataGridTemplateColumn();
           c.SortMemberPath = i.columnName;
           c.CellTemplate=new DataTemplate() { VisualTree = buttonTemplate };
           AddHeader(c,i);
           return c;
       }

Trying to replicate this using the RadGridView is giving me all sorts of problems, I think I'm going about it entirely wrong so I won't even post my failed attempts as I'm getting all sorts of bizarre errors.

How do I accomplish adding a button column dynamically in code to a RadGridView and setting it to my own event handler (there is an example on here but it's done in xaml and doesn't add an event handler for the button)?

Any help greatly appreciated.
