A Double value that specifies the column width in density-independent pixels.
This documentation topic describes legacy technology. We no longer develop new functionality for the GridControl and suggest that you use the new DataGridView control instead.
In the grid, column widths are adjusted automatically, so that the total width of all columns matches the grid width. Changing the width of one column automatically changes the widths of other columns. To obtain the actual width of columns, use their ActualWidth property.
