DevExpress XtraGrid 自定义 RowCellStyle 事件处理程序和列排序问题

Question

我的 xtraGrid 有一个自定义样式的事件监听器:

  FooGridView.RowCellStyle += new DevExpress.XtraGrid.Views.Grid.RowCellStyleEventHandler(FooGridView_RowCellStyle);


  private void FooGridView_RowCellStyle(object sender, DevExpress.XtraGrid.Views.Grid.RowCellStyleEventArgs e)
        {

            DevExpress.XtraGrid.Views.Grid.GridView vw = (sender as DevExpress.XtraGrid.Views.Grid.GridView);
            try
            {
                DataRow DR = vw.GetDataRow(vw.GetRowHandle(e.RowHandle));

                if (**some condition based on one or more values in the DataRow**)
                {
                    e.Appearance.Font = new System.Drawing.Font(e.Appearance.Font, System.Drawing.FontStyle.Strikeout);
                    e.Appearance.ForeColor = Color.LightGray;
                }
                else
                {
                    e.Appearance.Font = new System.Drawing.Font(e.Appearance.Font, System.Drawing.FontStyle.Regular);
                    e.Appearance.ForeColor = Color.Black;
                }

            }
            catch (Exception ex) { }
        }

单击网格列标题以重新排列网格后，在对行重新排序后，格式最终会应用于错误的行。如何解决这个问题？

Answer 1

您正在服用e.RowHandle给您并将其转换为 DataSourceHandle .然后，您调用GetDataRow与 DataSourceHandle .

但是，GetDataRow接受行句柄，而不是数据源句柄。试试这个:

DataRow DR = vw.GetDataRow(e.RowHandle);
