I have used a SplitButton with two menu items on my form.  The menuitems are two - RadMenuItem1 has a text property "Ver 1" and RadMenuItem2 has a text propery "Ver 2" 
(The togglebutton is not an option as I will have some other forms which may have more than two menu items).
The problem is when I select the option Ver 2 the code for "Ver 1" is executing and vice versa.
Placing a messagebox shows the problem.

Please help.

I use the following code:
   Private Sub RadMenuItem1_Click(sender As Object, e As System.EventArgs) Handles RadMenuItem1.Click
        'SetDefaultItem(RadMenuItem1)
        Me.RadSplitButton1.Text = "Ver 1"
    End Sub


    Private Sub RadMenuItem2_Click(sender As Object, e As System.EventArgs) Handles RadMenuItem2.Click
        'SetDefaultItem(RadMenuItem2)
        Me.RadSplitButton1.Text = "Ver 2"
    End Sub


    Private Sub RadSplitButton1_TextChanged(sender As Object, e As System.EventArgs) Handles RadSplitButton1.TextChanged
        Dim part As String = Me.RadSplitButton1.Text

MsgBox(part)  'you will see the error here

        Select Case part       'Me.RadSplitButton1.Text


            Case "Part 1"
                Me.BOOKS2BindingSource.Filter = "VERSION = 'V1'"
                Me.RadPageViewPage1.Item.Visibility = ElementVisibility.Visible
                Me.RadPageView1.SelectedPage = Me.RadPageViewPage1


            Case "Part 2"
                Me.BOOKS2BindingSource.Filter = "VERSION = 'V2'"
                Me.RadPageViewPage1.Item.Visibility = ElementVisibility.Hidden
                Me.RadPageView1.SelectedPage = Me.RadPageViewPage2


        End Select






    End Sub

Hello Ahmuser,

Thank you for writing.

I am writing to confirm that the TextChanged event of the control is actually fired before the text is changed. I have logged this issue into our Public Issue Tracking System and we will address it in a future release. Feel free to follow this link, where you can add your vote for this issue, and also you can subscribe for its status updates.

Your Telerik points have been updated for this report.

In the meantime, you can work around this by subscribing to the TextChanged event of the ActionButton:
Public Sub New()
    InitializeComponent()
 
    AddHandler RadSplitButton1.DropDownButtonElement.ActionButton.TextChanged, AddressOf ActionButton_TextChanged
End Sub
 
Private Sub ActionButton_TextChanged(ByVal sender As Object, ByVal e As EventArgs)
    Dim part As String = Me.RadSplitButton1.Text
        MsgBox(part)  'you will see the error here
        Select Case part       'Me.RadSplitButton1.Text
            Case "Part 1"
                Me.BOOKS2BindingSource.Filter = "VERSION = 'V1'"
                Me.RadPageViewPage1.Item.Visibility = ElementVisibility.Visible
                Me.RadPageView1.SelectedPage = Me.RadPageViewPage1
            Case "Part 2"
                Me.BOOKS2BindingSource.Filter = "VERSION = 'V2'"
                Me.RadPageViewPage1.Item.Visibility = ElementVisibility.Hidden
                Me.RadPageView1.SelectedPage = Me.RadPageViewPage2
        End Select
End Sub

Another possible approach is to spread your logic in the appropriate RadMenuItem1 and RadMenuItem2 click event handlers:
Private Sub RadMenuItem1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RadMenuItem1.Click
       'SetDefaultItem(RadMenuItem1)
       Me.RadSplitButton1.Text = "Ver 1"
       Me.BOOKS2BindingSource.Filter = "VERSION = 'V1'"
       Me.RadPageViewPage1.Item.Visibility = ElementVisibility.Visible
       Me.RadPageView1.SelectedPage = Me.RadPageViewPage1
   End Sub
 
   Private Sub RadMenuItem2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RadMenuItem2.Click
       'SetDefaultItem(RadMenuItem2)
       Me.RadSplitButton1.Text = "Ver 2"
       Me.BOOKS2BindingSource.Filter = "VERSION = 'V2'"
       Me.RadPageViewPage1.Item.Visibility = ElementVisibility.Hidden
       Me.RadPageView1.SelectedPage = Me.RadPageViewPage2
   End Sub

I hope the provided information addresses your question.

A bit off topic, I would like to remind you that in order to continue receiving support from us, you will have to provide us with the requested information in thread "Multiline RadListControl", or take one of the steps described there. You can find this thread in Your Account.

I am looking forward to your reply.
 
All the best,
Stefan
