AutoComplete box doesn't work after moving RadDock it is on

[Steven]

Hello,

Im experiencing an issue where I have an RadAutoCompleteBox on a RadDock and it functions properly when the RadDock remains in the default position, 

However, when I move the raddock out of the raddockzone it is in, the RadAutoCompleteBox acts as if there are no results, despite having results when I step through the code that fills its datasource. 

below is the snippet of code that fills the AutoCompleteBox Datasource

        protected void ddlDeviceType_ItemSelected(object sender, Telerik.Web.UI.DropDownListEventArgs e)
        {
            type = ddlDeviceType.SelectedText;

            cboDeviceAssign.Entries.Clear();
            cboDeviceAssign.DataSource = Devices;
            cboDeviceAssign.DataTextField = "Device";
            cboDeviceAssign.DataValueField = "Device";
            cboDeviceAssign.DataBind();
        }

Hello Steven,

I have tested the described behavior and was not able to replicate the issue with the attached project as demonstrated in this screencast: http://somup.com/cq6u6KffXr

Would you please modify the attached project so that it better represents your scenario and replicates the issue and send it back to us in an official support ticket. That would allow us to investigate locally your exact scenario and provide more accurate and specific suggestions. A screencast or a live URL to a website showing the exact reproduction steps are greatly appreciated.

protected void Page_Load(object sender, EventArgs e)
{
    RadAutoCompleteBox1.DataSource = new List<string>() { "Europe", "America", "Asia", "Africa", "Australia" };
}

<telerik:RadDockZone ID="RadDockZone2" runat="server" Orientation="Vertical" Width="450px"
    MinHeight="400px">
    <telerik:RadDock RenderMode="Lightweight" ID="RadDock1" runat="server" Title="Blogs" Width="400px" EnableAnimation="true"
        EnableRoundedCorners="true" Resizable="true" CssClass="higherZIndex">
        <ContentTemplate>
            <telerik:RadAutoCompleteBox RenderMode="Lightweight" ID="RadAutoCompleteBox1" runat="server" Width="400" DropDownHeight="150"
                EmptyMessage="Select Continents">

        </ContentTemplate>
    </telerik:RadDock>
</telerik:RadDockZone>
