combobox not show in dynamic usercontrol.

[trunghth]

Hi,
I got a problem with radcombox like here:

addReportDocByVTHS.ascx
<telerik:RadComboBox ID="ddltype" runat="server" Label="Doc Type: " Width="200px">

</telerik:RadComboBox>

and in my parent usercontrol i call addReportDocByVTHS.ascx like this:

UserControl_ReportDoc_addReportDocByVTHS control = (UserControl_ReportDoc_addReportDocByVTHS)this.Page.LoadControl("~/Usercontrol/ReportDoc/addReportDocByVTHS.ascx");

        if (control != null)

        {         

            control.modalContainer = pnlInsert_ModalPopupExtender.ID.ToString();

            control.AfterClickLuu += new EventHandler(btsearch_Click);

            if (!pnlInsert_child.Controls.Contains(control))

            {

                pnlInsert_child.Controls.Add(control);

                pnlInsert_ModalPopupExtender.Show();

            }

            Session["action"] = "insert";

        }
//load dropdownlist
ddltype.DataSource = F_DocType.GetList();
        ddltype.DataTextField = "DOC_TYPENAME";
        ddltype.DataValueField = "DOC_TYPE";
        ddltype.DataBind();


here is my parent usercontrol.ascx like:

<asp:UpdatePanel ID="UpdatePanel1" runat="server" >
<ContentTemplate>
<asp:HiddenField ID="hdfMacv" runat="server" />
<asp:ModalPopupExtender ID="pnlInsert_ModalPopupExtender" runat="server"
     Enabled="True" TargetControlID="hdfMacv" PopupControlID="pnlInsert"
    BackgroundCssClass="modalBackground"
    ></asp:ModalPopupExtender>

<asp:Panel ID="pnlInsert" runat="server" CssClass="ModalWindow"  style="display:none">
        <asp:PlaceHolder ID="pnlInsert_child" runat="server" EnableViewState="false">
        </asp:PlaceHolder>
</asp:Panel>
    </ContentTemplate>
    </asp:UpdatePanel

My combobox can't shown down when i click, i only can press "up" and "down" keyboard to choose.

Hello Hua,

I have tried to replicate the described issue, but to no avail. I have prepared a sample project for you, demonstrating the behavior at my end. Would you give it a try at your end and let me know if I had missed something? In addition, would you specify under which browser you are encountering the problem and which is the version of our controls that you are using?

Note : dll files are removed from the attachment.
