排序数据时，在数据绑定的DGV中保留DataGridViewRow.Tag属性 [英] Preserve DataGridViewRow.Tag property in databound DGV when sorting data

问题描述

是否有一种方法可以防止在对网格进行排序后立即使标签为空？

Is there a way to keep the tags from being nulled as soon as I sort the grid?

如果没有，那么Tag属性除非-databound用法？

If not, is the Tag property actually useful for anything except non-databound usage?

推荐答案

根据您的最后一个问题，您正在设置DataGridViewRow对象的Tag。而且很可能在排序操作期间重新创建它们。确保使用反射器，但是我将开始寻找解决方法。

Based on you last question, you are setting the Tag of DataGridViewRow objects. And they might very well be re-created during a Sort operation. Use reflector to make sure, but I would start looking for a workaround.

通常，Tag属性是不得已的选择。

In general, the Tag property is a last resort.

您可以使用 Dictionary< object，object> 将数据耦合到 dgvr.DataBoundItem 作为键。

You could use a Dictionary<object, object> to couple your data to the dgvr.DataBoundItem as key.
