如果柱子剂量不包含任何值, 我如何从 Grid 视图中删除或删除柱子?
您可以为您要测试的列指定一个全局布尔, 例如 :
bool columnHasValues = false;
然后在 GridView.RowTroundDataBound 事件中,您将测试该列的值 :
if (!columnHasValues)
columnHasValues = !(string.IsNullOrEmpty(e.Row.Cells(columnIndex).Text);
对于 < Net4.0 将 < code> isnullorEmpty 更改为 < code> Isnull Or whitespace 。 然后,在 < code> Page_ page_ prererender 事件上,您将设置该列的可见度以匹配 columnHasValues 的值。
