The Width property resizes a column at runtime. Use the AutoWidth property to compute the width that's required to fit all cells in the column. Use the WidthAutoResize property to automatically resize the column while the user expands or collapses items. Use the Visible property to hide a column. The ColumnAutoResize property specifies whether the visible columns fit the control's client area. If the ColumnAutoResize property is True, the Width property may not resize the column to the desired value, because all visible columns must fit the control's client area. By default, the control adds horizontal scroll bar when required. Use the ScrollBars property to add or remove the control's scroll bars. Use the Visible property to hide the column. Use the FilterBarDropDownWidth property to specify the width of the drop down filter window.
