FocusControl() does not work

[Lucas County Information Services]

I have a form containing three (3) RadComboBoxes. When an item is selected from the first combobox the other two are updated and the focus is supposed to be set on the second combobox. The problem is that the focus is not be set to the second combobox after it has been rebound. What is wrong here?

    Protected Sub radCombo1_SelectedIndexChanged(ByVal o As Object, ByVal e As Telerik.Web.UI.RadComboBoxSelectedIndexChangedEventArgs) Handles radCombo1.SelectedIndexChanged
        BindCombo2()
        If radCombo3.Text.Length = 0 Then
            BindCombo3()
        End If

        radAjaxManager.FocusControl(radCombo2.ClientID & "_Text")
    End Sub

Thanks so much. That resolved the issue.

I also needed to use this where the radComboBox was in a GridView control. After setting the focus to the combobox I needed the text to be highlighted. When searching the forums I found plenty of examples where the combobox was located on a form, but not inside of a grid. The solution was pretty simple though. In the ASP for the combobox, add the OnClientFocus event:

<telerik:RadComboBox ID="radCombo2" runat="server"
                     MarkFirstMatch="true"
                     OnClientFocus="radCombo2_OnFocus"  />

Then add this function to a script block:

function radCombo2_OnFocus(sender)
{
    sender.selectText(0, sender.get_text().length);
}

I hope this helps somebody else.
