解决方法：

请参考以下代码：

private void gvTimeGroup_CustomDrawCell(object sender,
DevExpress.XtraGrid.Views.Base.RowCellCustomDrawEventArgs e)
         {
             if (e.Column.FieldName == "IsFinished")
             {
                 DevExpress.XtraEditors.ViewInfo.ButtonEditViewInfo buttonEditViewInfo =

(DevExpress.XtraEditors.ViewInfo.ButtonEditViewInfo)

((DevExpress.XtraGrid.Views.Grid.ViewInfo.GridCellInfo)e.Cell).ViewInfo;
 
                if (e.CellValue.Equals("1"))//判断条件，具体情况另行修改
                 {
                     buttonEditViewInfo.RightButtons[0].Button.Enabled = false;//必须有，否则即

使button状态为灰色，但点击还会触发事件
                     buttonEditViewInfo.RightButtons[0].State =

DevExpress.Utils.Drawing.ObjectState.Disabled;
                 }
                 else
                 {
                     buttonEditViewInfo.RightButtons[0].Button.Enabled = true;
                     buttonEditViewInfo.RightButtons[0].State =

DevExpress.Utils.Drawing.ObjectState.Normal;
                 }
             }
         }
