Property Value

Type Default Description
Int32 0

An integer value specifying the x-coordinate of the popup window’s left side.


The Left property is not in effect for a popup window if the window’s PopupWindow.PopupElementID property is specified.

The Left property allows you to specify a value that represents the x-coordinate of a popup window’s left side. To completely define the popup window’s position, you must specify a value for this property and for the PopupWindow.Top property. A popup window can be displayed at the specified position if the window’s PopupWindow.ShowOnPageLoad property is set to true or by calling the client ASPxClientPopupControl.ShowWindow method which references this window.


You cannot specify a common x-coordinate for the left side of all popup windows from the ASPxPopupControl.Windows collection by using the popup control’s ASPxPopupControlBase.Left property. This property is not in effect when the ASPxPopupControl.Windows collection is not empty. In this case, you should use the Left property whose value is typically specific for each individual popup window.
