Details of the DisplayColumns property

The value assigned to the DisplayColumns property determines the number of columns that appear within the GraphicRepeaterApp during runtime. A non-zero value shows graphics in the specified number of columns and the graphics are scaled to fit the width of each column. The remaining graphics beyond the column limit appear on the next row of the view pane.

A value of zero indicates the DisplayColumns property is ignored and graphics appear in the viewer window in as many columns as calculated based on the values of other GraphicRepeaterApp properties.
