title: Specify the max number of columns for a WrapPanel in WPF
body: <p>I have a WrapPanel, And I want to specify the Max number of its columns. So, for example, when my Collection "ObjectCollection" (binded to this WrapPanel) contains only 4 elements, the WrapPanel will have only one row. But, when "ObjectCollection" will have 5 elements, the wrapPanel will create another row to put the fifth one. (My Max_Columns_Number in this case is 4).</p>
