推荐答案

这个问题没有感。发布一些代码，以便我们知道你的意思。您可以使用javascript隐藏UI中的行，但删除行的最佳方法是从数据源中删除它们。

This question makes no sense. Post some code so we know what you mean. you can hide rows in the UI with javascript, but the best way to remove rows, is to remove them from the data source.

在数据库表中添加另一列作为位类型网格视图绑定。

并在按钮点击事件上更新该列的值。

将gridview绑定为

Add another column as bit type in database table by which your grid view bind.
and update value of that column on button click event.
bind gridview as

select *from table1 where status=false.

$ b更新record.as后$ $绑定gridview.as

bind gridview after updateing record.as

gridview1.DataBind();
