Hi Raja,

with reference to this form thread it is not possible to access the mainpage.aspx RadComboBox in the Page1.aspx. There is no relation between the mainpage.aspx and pages in the ContentUrl. As for your second question  the Page1.aspx will get refresh whenever a postback happens. Please take a look into the sample code snippet.

ASPX:

<telerik:RadComboBox ID="rcb1" runat="server" AutoPostBack="true" OnSelectedIndexChanged="rcb1_SelectedIndexChanged">
</telerik:RadComboBox>
<telerik:RadTabStrip ID="radtab1" runat="server" MultiPageID="radmulti1" SelectedIndex="0">
    <Tabs>
        <telerik:RadTab runat="server" Text="Discipline" PageViewID="pageview1" Selected="True">
        </telerik:RadTab>
    </Tabs>
</telerik:RadTabStrip>
<telerik:RadMultiPage ID="radmulti1" runat="server" Width="400" SelectedIndex="0">
    <telerik:RadPageView ID="pageview1" runat="server" ContentUrl="Page1.aspx">
    </telerik:RadPageView>
</telerik:RadMultiPage>

Page1.ASPX:

<asp:TextBox ID="textBox1" runat="server" Text="Demo">
</asp:TextBox>

Thanks,
Shinu.

Actually, the reply given by Shinu; "it is not possible to access the mainpage.aspx RadComboBox in the Page1.aspx" is not entirely true.  I had a need for that and accomplished it as follows:

​

public partial class Default : System.Web.UI.Page
{
    // declare a static variable that will point to this page (set in Page_Load())
    public static Page thisPage = null;

    protected void Page_Load(object sender, EventArgs e)
    {
        thisPage = this;
    }

    public static RadComboBox cbxManagers
    {
        get
        {
            RadComboBox rc = (RadComboBox)findControl(thisPage, "_cbxManagers");
            // if it's not found, return something that won't bomb out the calling page
            if (rc == null)
                rc = new RadComboBox();
            return rc;
        }
    }

    // function to loop through all controls starting with ctrl
    public static Control findControl(Control ctrl, string ID)
    {
        if (ctrl != null)
        {
            Control cl2;
            foreach (Control cl in ctrl.Controls)
                if (cl.ID == ID)
                    return cl;
                else
                    if (cl.HasControls())
                    {
                        cl2 = findControl(cl, ID);
                        if (cl2 != null && cl2.ID == ID)
                            return cl2;
                    }
        }
        return null;
    }
}

// Then, in the page assigned to the ContentUrl

    private RadComboBox cbxManagers
    {
        get
        {
            return Default.cbxManagers;
        }
    }
