Hello Ken,

The code below works at our side in IE8:

//aspx:

<asp:ScriptManager ID="ScriptManager1" runat="server">
    </asp:ScriptManager>
    <telerik:RadComboBox ID="RadComboBox1" runat="server"
        AllowCustomText="True">
        <Items>
            <telerik:RadComboBoxItem runat="server" Text="N" />
            <telerik:RadComboBoxItem runat="server" Text="S" />
            <telerik:RadComboBoxItem runat="server" Text="E" />
        </Items>
    </telerik:RadComboBox>

    <telerik:RadAjaxManager ID="Manager1" runat="server">
        <AjaxSettings>
            <telerik:AjaxSetting AjaxControlID="Button1">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="RadComboBox1" />
                </UpdatedControls>
            </telerik:AjaxSetting>
        </AjaxSettings>

    </telerik:RadAjaxManager>


    <asp:Button ID="Button1" runat="server" onclick="Button1_Click"
        Text="Focus ComboBox" />

//vb:

Protected Sub Button1_Click(sender As Object, e As EventArgs)
    ScriptManager1.SetFocus(RadComboBox1.ClientID + "_Input")
End Sub

Does it work at your side?

I'm sorry, It does not work.
First, When I add <asp:ScriptManager element in my ascx, It's show messeage :"ScriptManager ... unknow element".
I search around, I down AjaxToolKit.Dll  ver 3.5 (I use .NET framework 3.5).Then include I found  asp:ToolkitScriptManager
and put below on Page_Load

If(AJAX.IsInstalled()) Then AJAX.RegisterScriptManager() End If

..... on Button_Click
    ToolkitScriptManager1.SetFocus(cboMaDichVu.ClientID + "_Input")

But also not work.

I use Donetnuke 5.5 & uncheck partial rendering.
I uncheck Partial Rendering beacause I have used telerik:RadAjaxManager
Thanks for advance.

Hello Ken,

Could you please send us a sample project which demonstrates the issue to examine it locally?

I have work around my problem.
When I spend my time for find out solution , I recognize that when event of client javascript excute, then event setfocus of ScriptManager from code behind will be effect.
So that I try with below code, and It's work at both IE7 & IE8.
It's look like a double focus but you can replace the focus event by RegisterStartupScript with another event some kind like show alert messenge, focus other control, then finally ScriptManager1.SetFocus will be work.

Dim script As String
script = "var comboBox = document.getElementById('" & cboMaDichVu.ClientID & "_Input');"
script += "comboBox.focus();"
ScriptManager.RegisterStartupScript(Page, Page.GetType(), "script", script, True)
Dim ScriptManager1 As New ScriptManager
ScriptManager1.Page = Page
ScriptManager1.SetFocus(cboMaDichVu.ClientID + "_Input")
