Hello,

I am unsure as to the issue. The RadMenuItems will open the sub menus when you hover over them which is the desired way a context menu should perform. I have included a small samepl for you below. If this is not what you mean, then please let me know and I'll do my best to help.

Designer File
<Global.Microsoft.VisualBasic.CompilerServices.DesignerGenerated()> _
Partial Class Form1
    Inherits System.Windows.Forms.Form
  
    'Form overrides dispose to clean up the component list.
    <System.Diagnostics.DebuggerNonUserCode()> _
    Protected Overrides Sub Dispose(ByVal disposing As Boolean)
        Try
            If disposing AndAlso components IsNot Nothing Then
                components.Dispose()
            End If
        Finally
            MyBase.Dispose(disposing)
        End Try
    End Sub

Thanks for the reply Richards
I implement your given code in the (context menu showing) function but the problem is that the sub items still remain disabled when i take the mouse on its parent item.
I modified ur code like this.

 

Private

 

 

Sub RadSchdAppView_ContextMenuShowing(ByVal sender As Object, ByVal e As Telerik.WinControls.UI.SchedulerContextMenuShowingEventArgs) Handles RadSchdAppView.ContextMenuShowinge.ContextMenu.Items.Add(New RadMenuItem("Level 1 - 1"))
e.ContextMenu.Items.Add(
New RadMenuItem("Level 1 - 2"))
e.ContextMenu.Items.Add(
New RadMenuItem("Level 1 - 3"))
e.ContextMenu.Items.Add(
New RadMenuItem("Level 1 - 3"))
CType(e.ContextMenu.Items(1), RadMenuItem).Items.Add(New RadMenuItem("Level 2 - 1"))
CType(e.ContextMenu.Items(1), RadMenuItem).Items.Add(New RadMenuItem("Level 2 - 2"))
End sub

please help me on this..

I am working in radschedular context menu there are 5 items in my customized context menu and one of the items have submenu (childrens) in it. The (submenu) children item's mouse hower doesnt get enabled untill i explicitly click on its parent item.
I want mouse hower property to get enabled when i take the mouse on its parent item.


Here i m attaching my code.....

  Private Sub RadSchdAppView_ContextMenuShowing(ByVal sender As Object, ByVal Telerik.WinControls.UI.SchedulerContextMenuShowingEventArgs) Handles RadSchdAppView.ContextMenuShowing

If (e.ContextMenu.Items.Count > 0) Then
            For i As Integer = e.ContextMenu.Items.Count - 1 To 3 Step -1
                Dim item = e.ContextMenu.Items(i)
                item.Visibility = Telerik.WinControls.ElementVisibility.Collapsed
            Next
        End If

        Dim lAppointmentStatus As New List(Of AppointmentStatusBO)
      
        ''MenuItem for Appointment .......
        'Dim Edit As RadMenuItem = New RadMenuItem()
        'Edit.TextImageRelation = System.Windows.Forms.TextImageRelation.ImageBeforeText
        'e.ContextMenu.Items.Insert(2, Edit)
        'Edit.Text = "Edit Appointment"
        'Edit.TextSeparatorVisibility = True

        Dim Status As RadMenuItem = New RadMenuItem()
        e.ContextMenu.Items.Insert(3, Status)
        Status.Text = "Appointment Status"

          Status.Items.Insert(0, new radmenuitem)
          Status.Items(i).Text = " Arrived"   
            
          Status.Items.Insert(0, new radmenuitem)
          Status.Items(i).Text = " Cancelled"   
            
               
 
        Dim Eligibility As RadMenuItem = New RadMenuItem()
        e.ContextMenu.Items.Insert(4, Eligibility)
        Eligibility.Text = "Run Eligibility"

        Dim GoToChart As RadMenuItem = New RadMenuItem()
        e.ContextMenu.Items.Insert(5, GoToChart)
        GoToChart.Text = "Go To Chart"

        Dim StartPhysicalEncounter As RadMenuItem = New RadMenuItem()
        e.ContextMenu.Items.Insert(6, StartPhysicalEncounter)
        StartPhysicalEncounter.Text = "Start Physical Encounter"

        Dim StartPhoneEncounter As RadMenuItem = New RadMenuItem()
        e.ContextMenu.Items.Insert(7, StartPhoneEncounter)
        StartPhoneEncounter.Text = "Start Phone Encounter"

        Dim ViewDemographics As RadMenuItem = New RadMenuItem()
        e.ContextMenu.Items.Insert(8, ViewDemographics)
        ViewDemographics.Text = "View Demographics"

End sub

Hello,

Thanks for clarifying this. From what I see of your code, you don't seem to be doing anything wrong. I've looked through the Public Issue tracking System and not found a related bug for it there, however, as far as I'm aware, this is an issue that Telerik will need to fix in an upcoming release.

All the best

Hello,

Richard, thank you for the community efforts.

Asif, this is a known issue and we will address it in a future release. If more people ask for it, we will increase its priority in our ToDo list.

All the best,
