Hello Eric,

To create a document in RadDock from a button click, consider the following code

Private Sub RadMenuItem1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RadMenuItem1.Click
    Dim documentTop As DocumentWindow = New DocumentWindow()
    documentTop.Text = "New Document"
    Me.RadDock1.AddDocument(documentTop)
End Sub

For more information on creating windows at runtime, please take a look at the following documentation

hope that helps

okay great! how can I do a check to make sure only 1 tab gets created. so lets say they cant keep clicking the button and more will generate

Hi Eric,

Just move the document to private and check to see if it is nothing. E.g.

Private m_DocumentTop As DocumentWindow
Private Sub RadMenuItem1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RadMenuItem1.Click
    If m_DocumentTop Is Nothing Then
        m_DocumentTop = New DocumentWindow()
        m_DocumentTop.Text = "New Document"
        Me.RadDock1.AddDocument(m_DocumentTop)
    End If
End Sub

Hope that helps

Okay thanks, but how come when i  X out of the new window and click the button to create it again. it will not create. its not going back to null;

Hi Eric,

If you are allowing close, but still only want to show one, then you can use the folliwing solution:

Private WithEvents m_DocumentTop As DocumentWindow
Private Sub RadButton1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RadButton1.Click
    Dim canCreate As Boolean
    If m_DocumentTop Is Nothing Then
        canCreate = True
    Else
        If Not m_DocumentTop.DockState = DockState.TabbedDocument Then
            canCreate = True
        End If
    End If
    If canCreate Then
        m_DocumentTop = New DocumentWindow()
        m_DocumentTop.Text = "New Document"
        Me.RadDock1.AddDocument(m_DocumentTop)
    End If
End Sub

Hope that helps

Hello Eric,

My apologies, it was rather late when I posted the code last night. This is much cleaner. (presuming you want to show the same document each time, and not a new one)

Private m_Document As New DocumentWindow()
Private Sub RadButton1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RadButton1.Click
    m_Document.Text = "New Document"
    m_Document.CloseAction = DockWindowCloseAction.Hide
    Me.RadDock1.AddDocument(m_Document)
End Sub

It just makes sure that the current document window is hidden, can only be shown once, and can be closed and re-shown
Let me know if you have any questions
Richard
