Grid Scrolling and Column Resizing Specifics
When ASPxCardView uses vertical scrolling, it renders a table with a fixed table layout. A browser calculates the grid’s dimensions to display it on a page. If dimension properties are not defined in ASPX markup (the grid’s ASPxWebControl.Width, the grid column’s WebColumnBase.Width, etc.), then the minimum width of the rendered tables is defined by the browser - so that they appear collapsed.
Therefore, the width dimension properties should be specified if you use scrolling.
