Gets or sets a value that indicates whether the user can change the column display order by dragging column headers with the mouse.
Assembly: PresentationFramework (in PresentationFramework.dll)
You can set this reorder behavior for individual columns by setting the DataGridColumn::CanUserReorder property. If the DataGridColumn::CanUserReorder property and the property are both set, a value of false will take precedence over a value of true.
Columns can be frozen by setting the FrozenColumnCount property greater than 0. Frozen columns are always the leftmost columns in display order. You cannot drag frozen columns into the group of unfrozen columns or drag unfrozen columns into the group of frozen columns.
