i am working with RadDiagram and customizing the Style Tab of  setting Pane using this code :-

<telerik:RadComboBox telerik:SettingsPaneView.EditorItemType="Shapes, Connections"
                                                     telerik:SettingsPaneView.EditorPropertyName="StrokeDashArray"

                                    </telerik:RadComboBox.SelectionBoxTemplate>

But using this code, when change the selection of Border combo box, drop down is open , and select item then drop down does not colse
and selected item is not show in combo box. 

Please suggest me something.
Thanks in advanced.

Hi Yogendra,

First, I wonder why the RadComboBox has no ItemsSource set. I used the following code:

                                    <telerik:RadComboBox telerik:SettingsPaneView.EditorItemType="Shapes, Connections"
                                                     telerik:SettingsPaneView.EditorPropertyName="StrokeDashArray"
                                                         ItemsSource="{data:StrokeDashArray}"
                                                     telerik:SettingsPaneView.EditorValue="{Binding SelectedItem,
                                                                                                    Mode=TwoWay,
                                                                                                    RelativeSource={RelativeSource Self}}">
                                        <telerik:RadComboBox.ItemTemplate>
....

and everything worked successfully. Could you please check it out in our test project and let us know if it helps you proceed further? Regards,
