Hello,

On page 52 (pg 40 in print PDF) "Context Menus", I'm doing the lesson on pages 53 - 55, however the context menu does not expand to show all the various options as shown on page 55. 

I copied and pasted the code in my project, but I kept getting a compilation error targeting "Imports Telerik.Web.UI (in red):
"Compiler Error Message: ASPNET: Make sure that the class defined in this code file matches the 'inherits' attribute, and that it extends the correct base class (e.g. Page or UserControl)."  

Once I deleted the "Namespace Multipage" keyword structure.  I don't understand why I was getting a compilation error just by using the namespace. ??? 

Here is the code per the lesson (as well as in my project):

 

Protected Sub RadContextMenu1_ItemClick(ByVal sender As Object, ByVal e As  
Telerik.Web.UI.RadMenuEventArgs)  
' look only at child items  
If e.Item.Level = 1 Then  
' find child items under "Colors" parent item  
If (TryCast(e.Item.Parent, RadMenuItem)).Text.Equals("Colors") Then  
' set the color picker preset to the selected preset  
RadColorPicker1.Preset = DirectCast([Enum].Parse(GetType(ColorPreset), e.Item.Text),  
ColorPreset)  
End If  
End If  
End Sub  
End Class 

So my two questions would be:
1. Why is deleting the "Namespace" keyword eliminating the compilation error?  I thought creating and using Namespaces is a way to
"package" classes.  Thus, making them more unique.

2.  Why is the  RadContextMenu control working correctly in my application for the RadColorPicker control?  (All I see when I right-click is the word "Color".  No subitems as shown on page 43.

Thanks,
R2

Hello R2,

The RadContextMenu tutorial which you have followed uses the previous project wit RadTabstrip as a starting point. You need to create the previous project to be able to use the Multipage namespace.

I have tested the tutorial in a simple website and everything worked well. Please, see the attached demo for reference.


Kind regards,
