Return Value
A list of the columns whose Visible property is true, ordered according to their VisiblePositions. By default, a null reference (Nothing in Visual Basic).Remarks
The VisiblePosition property represents the visible position of the column in a grid and may, or may not, correspond to the Index property. A column's visible position can be regarded as the position the column will take when it is visible. Changing a column's visibility will not affect its visible position, allowing the visibility of columns to be changed without them being reordered. To retrieve the effective visible position of a column, the IndexOf method of the VisibleColumns collection can be used.
When fixing columns in a table-view layout, columns will be fixed in the order represented by their VisiblePosition properties. For example, if the FixedColumnCount property is set to 2, then the columns whose VisiblePosition properties are 0 and 1 will be fixed.
If a grid contains hidden columns, they will be ignored. For example, if the second and third columns are hidden and a fixed-column count of 2 is provided, the first and fourth columns will be fixed but their visible positions will not be modified to reflect their new positions.
