DevExpress控件GridControl中的列冻结详解

               //冻结有焦点的列
int fixcolumn = 0;
                GridColumn column = m_gridView.FocusedColumn;
                if (column == null)
                    return;
                fixcolumn = column.VisibleIndex;
                for (int i = 0; i < fixcolumn; i++)
                {
                    m_gridView.VisibleColumns[i].Fixed = DevExpress.XtraGrid.Columns.FixedStyle.Left;
                }

               
                //取消冻结【说明:以下这种取消冻结后，就会出现列的位置倒置的情况】
                for (int i = 0; i < fixcolumn; i++)
                {
                    m_gridView.VisibleColumns[i].Fixed = DevExpress.XtraGrid.Columns.FixedStyle.None;
                }

                         //正确的取消冻结[倒置进行取消冻结],这样就可以保证冻结前与冻结后的列的位置保持一致

                 for (int i = fixcolumn; i >=0 ; i--)
                {
                    m_gridView.VisibleColumns[i].Fixed =DevExpress.XtraGrid.Columns.FixedStyle.None;
                }
