Hi,
I have a problem with an "ASPxPopupControl."
I have created the popup with:
<dxpc:ASPxPopupControl ID="ASPxPopupControlDataView" runat="server" AllowDragging="True"
AllowResize="True" CloseAction= "CloseButton"
EnableViewState="False" PopupElementID="blueArea"
ShowOnPageLoad="False" ClientInstanceName="ASPxPopupControlDataView"
EnableHierarchyRecreation="True">
<ContentStyle>
<Paddings PaddingBottom="0px" PaddingLeft="0px" PaddingRight="0px"
PaddingTop="0px" />
</ContentStyle>
<ContentCollection>
<dxpc:PopupControlContentControl ID="PopupControlContentControl1" runat="server"></dxpc:PopupControlContentControl>
</ContentCollection>
</dxpc:ASPxPopupControl>
and I need, in run time to show the popup in modal mode in the center of the page:
function popUpReport()
{ ASPxPopupControlDataView.PopupHorizontalAlign="WindowCenter";
ASPxPopupControlDataView.PopupVerticalAlign="WindowCenter";
ASPxPopupControlDataView.Modal="true";
ASPxPopupControlDataView.Show();}
The setting of the properties on run time have no effect, the popup is show in no-modal mode and in the top left corner of the page.
Where is the error? 
Thank you.
