WPFP DataGrid 绑定速度非常慢, 与大数据( ~ 75k) 在单元格内调整大小( ~ 75k)
原标题:WPF DataGrid is very slow to bind, resize with large data (~75k) within a cell

我有一个 WPF DataGrid 数据, 我从 SQL db 输入数据。 有些单元格的文本长度可达80公里。 即使不到10行, 这也使得数据Grid 连接数据的速度非常慢, 而重新缩放或滚动也非常慢 。

我正在考虑在数据对象中添加另一个属性,我拉动 SQL 数据,为显示目的将这些大字符串的截断版本(前30个字符数左右)添加到数据对象中。 然而,我想这并不是所有这种不寻常的情况,我想知道在DataGrid中是否有一个结构或模式来处理这一问题?

最佳回答

好吧,你不应该真的把80公里的文本数据 放在一个数据格瑞德, 这在各方面都是非常糟糕的设计。

增加一列带有节选文字的节选文字,如20个字符或20个字符,与该字符捆绑在一起,让用户或者用鼠标对着鼠标,或者打开儿童窗口,动态装入完整的数据集。
