推荐答案

方法1:
您需要做的是，一旦选择了要删除的行的复选框，就会触发回发事件，例如通过页面上的删除"按钮.

在后面的代码中，遍历网格行并获取选中了其复选框的行.相应地修改数据表/数据源.
提交对数据表/数据集所做的更改.
将此新数据表/数据集用作网格的数据源.重新绑定与此网格.

方式2:
单击复选框后，在隐藏字段中维护每行客户端的唯一键.在回发时，从此隐藏字段中获取所有行的唯一键，然后从数据集中删除这些行.将数据网格与此数据集重新绑定.

WAY 1:
What you need to do is, once you select the checkboxes of the rows that you want to delete, trigger a postback event like via Delete button on the page.

In code-behind, loop through the grid rows and get the row whose checkboxes are checked. Modify the datatable/datasource accordingly.
Commit the changes made to datatable/dataset.
Use this new datatable/dataset as a datasource of your grid. Rebind the grid with this one.

WAY 2:
On click of checkboxes, maintain the unique keys of each row client side in a hidden field. on postback, get all row unique keys from this hidden field and remove those rows from the dataset. Rebind the datagrid with this dataset.
