RadComboBox inside RadMultiPage

[Michael]

Recently I have using RadComboBox just fine with default skin. There is issue when I using RadComboBox inside RadMultiPage. Here is the case :
1. When the RadComboBox is initially loaded, it display correctly like in the first Screenshot (SS1). The arrow is shown normally.
2. My aspx is like this : 

    <telerik:RadMultiPage ID="RadMultiPage1" runat="server" SelectedIndex="0"></telerik:RadMultiPage>


3. When RadMultiPage is clicked, I load aspx to render into RadMultiPage. The Code is like this :  

    RadPageView pageView = new RadPageView();
    pageView.ID = item["ScreenID"].ToString();
    pageView.ContentUrl = GetScreenPath(int.Parse(item["ScreenID"].ToString())) + "?CPID=" + item["ContractParameterID"].ToString() + "&CID=" + ContractID + "&CTID=" + ContractTypeID + "&CGTID=" + ContractGroupTypeID;
    pageView.Width = new Unit(100, UnitType.Percentage);
    RadMultiPage1.PageViews.Add(pageView);

4. When content of PageView is loaded succesfully, it will call RadComboBox where the contents of the page  is rad ajax panel to wrap the RadComboBox. My aspx code for RadComboBox is like this :

<telerik:RadAjaxPanel ID="RadAjaxPanel1" runat="server"><telerik:RadComboBox ID="RadComboBox1" runat="server"> </telerik:RadComboBox></telerik:RadAjaxPanel>

5. After the second load, the arrow in right of RadComboBox is not shown. 
6. This issue only happen in IE10 (Compatibilty Mode IE8).

I am now using Telerik 2013 Q2. Can you help me to solve this issue?

Hi Michael,

I'm trying to follow the provided steps, but I have a few questions:

• How do you add PageView when RadMultiPage is clicked. It does not have OnClick event? Do you add it on a button click?
• How you determine when the content of the PageView is loaded successfully and  how you call RadComboBox.

It would be helpful if you paste little more code.

Thanks.
