DevExpress控件GridControl中的列冻结

 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;        

        }
