Restrict context menu for child controls

[sunu]

Hi

I have a master control GRID and within that I have two other controls. I have placed a context menu within the master control and have to restrict the menu in my other child controls

Please find the below code :

 

 

<radDock:RadDocking.DocumentHost>

 

 

 

<radDock:RadSplitContainer>

 

 

 

<telerik:RadContextMenu.ContextMenu>

 

 

 

<telerik:RadContextMenu x:Name="contextMenu">

 

 

 

<telerik:RadMenuItem Header="Add" x:Name="cMnuAdd">

 

 

 

<telerik:RadMenuItem Header="Class" x:Name="cMnuClass" Click="cMnuClass_Click"/>

 

 

 

<telerik:RadMenuItem Header="Association" x:Name="cMnuAssociation" Click="cMnuAssociation_Click"/>

 

 

 

</telerik:RadMenuItem>

 

 

 

</telerik:RadContextMenu>

 

 

 

</telerik:RadContextMenu.ContextMenu>

 

 

 

<radDock:RadPaneGroup>

 

 

 

<radDock:RadDocumentPane Title="Object Designer">

 

 

 

<radDock:RadDocumentPane.Content>

 

 

 

 

<ScrollViewer x:Name="ScrollViewer" HorizontalScrollBarVisibility="Visible" VerticalScrollBarVisibility="Visible">
<!-- Restrict the context menu here -->

 

 

 

<local:ObjectDesigner></local:ObjectDesigner>

 

 

 

</ScrollViewer>

 

 

 

</radDock:RadDocumentPane.Content>

 

 

 

</radDock:RadDocumentPane>

 

 

 

</radDock:RadPaneGroup>

 

 

 

</radDock:RadSplitContainer>

 

 

 

</radDock:RadDocking.DocumentHost>

Please let me know a solution for this. If this thread is already posted, then send me the link so that I can refer

Hello,

First I want to note that it is not a good idea to set properties on the RadSplitContainer and RadPaneGroup controls, since RadDocking can automatically dispose them if they are not needed, and later create new instances if needed. The code you sent will work if the users do not move the panes outside of the document host. I would recommend setting the context menu attached property on RadDocking, or on each RadPane/RadDocumentPane where it has to be displayed.

In case you use a single context menu for the whole RadDocking, or for a specific RadSplitContainer as in your code snippet, in the Opened event of RadContextMenu you can check if the user clicked on area where the menu should be visible or not and close it if needed using its IsOpen property.

For more information about the Opened event and a similar scenario, please, check my blog post:

Hi Valeri,
I am just starting out with RadControls (and WPF for that matter). I had in my project a RadTreeView usercontrol on a TabControlItem with a custom context menu. I have now moved this control onto a RadPane in a RadDocking section, but now my context meny no longer fires, instead the RadPane's fire. Any pointers?

Hello Renier,

Thank you for contacting us.

We are aware of this problem with RadDocking control. The RadPane's context menu overrides that you set to the RadTreeView control. I would suggest you to disable the RadPane's context menu. For more information, please refer to the following link - http://www.telerik.com/help/silverlight/raddocking-how-to-add-menu-items-to-the-radpanes-menu.html

I hope this helps.

Hi George,

Thanks for the feedback. I actually came across the same solution searching through the knowledgebase. Worked like a charm with a few keywords. Don't know how anyone programmes without the internet ;-)
