How I can set the focus of a RibbonComboBox built in a Ribbon Menu? Thanks! Gustavo

It seems to me there is no difference between comboboxes in a ribbon menu
and, for example, in a ribbon group. You may assign either the SelectedIndex
property or the SelectItem, such as:

RibbonComboBox1.SelectedIndex = 3
RibbonComboBox1.SelectedItem = RibbonButton2

Let me know if I'm misunderstanding your question.

There is actually a bug in the RibbonComboBox that prevents focusing items
from keyboard. We'll try to fix this bug ASAP, then I will let you know.

Hi Andrey!

Thank you for your prompt response. May be I didn't explain myself well enought.

I have a form that only has a ribbon on the top. The ribbon has a ONE BUTTON called connect. This connect option should be enabled if you type the right IP address in the combobox inside the Ribbon Menu. The problem I have is that I can't tell the cursor to go by default to the ComboBox. I need some sort of FOCUS function to tell the cursor where to start when the application starts.

What you suggested me didn't work, because I don't have elements in the list because is the first time someone is using it. The list will grow slowly in the future.

Hi Gustavo,

Yes, we have no the Focus() function in the ribbon items. We'll
consider adding such a function in the future versions. Right now
you may use a trick that allows to focus the ribbon combobox
when the application starts. See the sample in the attachment.

Here is the main code snippet from that sample:
-------------------------------------------------------------------
Private FirstTimeVisible As Boolean = True

Private Sub Form1_Load(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles MyBase.Load

AddHandler IPCombo.TextBox.VisibleChanged, _
AddressOf IPComboTextBox_VisibleChanged

End Sub

Private Sub IPComboTextBox_VisibleChanged(ByVal sender _
As System.Object, ByVal e As System.EventArgs)

If FirstTimeVisible Then

Dim tb As TextBox = IPCombo.TextBox
If tb.Visible And tb.Parent IsNot Nothing Then

tb.Focus()
FirstTimeVisible = False

End If

End If

End Sub
-------------------------------------------------------------------

Hope this will help.

Hi Andrey!

It didn't work. The first problem I have is that the system is not happy with Handles MyBase.Load statement.

Hi Gustavo,

How does the attached sample work?

The 'Handles MyBase.Load' statement declares that
the procedure handles the Form.Load event.

Let me know if you're working in C#.
