-Since column fixing is effective only with horizontal scrolling, using it makes sense only if the [columnAutoWidth](/api-reference/10%20UI%20Components/GridBase/1%20Configuration/columnAutoWidth.md '/Documentation/ApiReference/UI_Components/dxDataGrid/Configuration/#columnAutoWidth') property is **false** and when the total width of columns exceeds the container width. Otherwise, fixed columns behave just like regular ones.
+Column fixing works only with horizontal scrolling. If a user scrolls DataGrid horizontally, the fixed columns do not move. Horizontal scrolling is enabled when a total columns width is wider than the component width (or its container width if the component's width is not specified). If the total columns width is less than the component width, the fixed column behave like a regular column.
