    Here is the scenario:

    I have a RadWindow that opens a different ASPX page (so not using a Content Template)

    On this ASPX pages that is opened in the RadWindow, I have a RadCombobox with a lot of items.

    The RadWindow is AutoSized to the contents - of something like 600x400px.

    When you open the RadCombobox, which is positioned near the bottom of the RadWindow, the dropdown opens down, and you can only see a couple of options - it appears that the Dropdown is actually going quite a distance down the popup page, which now has scrollbars - just while this dropdown is open.  using the Scrollbars closes the dropdown and then the scrollbars disappear.  Using Chrome if that matters.

    Is there a way to force the RadCombobox in this scenario to stay within the Radwindow?  I have tried EnableScreenBoundaryDetection and ExpandDirection="Up" - but can't get anything to work.

    What am I doing wrong?

    Hi Dan,

    Unfortunately I couldn't replicate the issue at my end. Please have a look into the sample code snippet which works fine at my end.

    ASPX:
    <telerik:RadWindow ID="UserListDialog" runat="server" Title="Manage actions" AutoSize="true" />

    C#:
    protected void Page_Load(object sender, EventArgs e)
    {
        UserListDialog.NavigateUrl = "combobox.aspx?";
        UserListDialog.VisibleOnPageLoad = true;
    }

    combobox.aspx:
    <br />
    <br />
    <br />
    <telerik:RadComboBox ID="RadComboBox1" runat="server">
        <Items>
            <telerik:RadComboBoxItem Text="Item1" />
            <telerik:RadComboBoxItem Text="Item1" />
            <telerik:RadComboBoxItem Text="Item1" />
            <telerik:RadComboBoxItem Text="Item1" />
            <telerik:RadComboBoxItem Text="Item1" />
            <telerik:RadComboBoxItem Text="Item1" />
            <telerik:RadComboBoxItem Text="Item1" />
            <telerik:RadComboBoxItem Text="Item1" />
            <telerik:RadComboBoxItem Text="Item1" />
            <telerik:RadComboBoxItem Text="Item1" />
            <telerik:RadComboBoxItem Text="Item1" />
            <telerik:RadComboBoxItem Text="Item1" />
            <telerik:RadComboBoxItem Text="Item1" />
            <telerik:RadComboBoxItem Text="Item1" />
            <telerik:RadComboBoxItem Text="Item1" />
            <telerik:RadComboBoxItem Text="Item1" />
        </Items>
    </telerik:RadComboBox>

    Please have a look into the attached screen shot also.
    Let me know if you have any concern.
    Thanks,
    Shinu.
