Specifies the URL which points to the image displayed within the window footer by default.
SetFooterImageUrl(value: string): void
A string value that is the URL for the image displayed within the window footer.
All graphic file formats which can be interpreted by internet browsers are supported. The image's URL can represent either an absolute or relative path.
If a footer image is not initialized on the server side (the window's PopupWindow.FooterImage.Url and control's ASPxPopupControl.FooterImage.Url properties are not specified), the corresponding DOM element is not created. In this case, the SetFooterImageUrl property is not in effect.
