问题描述

我有一个GridView和其DataSource是GridView控件 datatable.OnRowDeleting 事件。我似乎无法删除该行，当我点击删除按钮调用该事件以删除该行。

I have a GridView and its DataSource is datatable.OnRowDeleting event of Gridview. I can't seem to delete that row when I click the 'delete' button that invokes the event to remove the row.

我的code是这样的GridView控件的 RowDeleting 事件：

My code is like this in RowDeleting event of GridView:

DataTable.Rows.Remove(GridView.DataKeys(e.rowindex).value)

我得到的错误：

I get the error:

不能键入从System.Int32中投地的System.Data.DataRow

有没有人有什么建议？

推荐答案

您可以找到通过查看 RowDeleting 事件中删除的行

You can find the row to delete inside the RowDeleting event by looking at the

e.RowIndex

您可以用 e.RowIndex 找到你的的DataTable正确的行，删除该行，然后刷新你的GridView 通过调用.databind（）就可以再次到数据表。

You can then use the e.RowIndex to find the proper row in your DataTable, delete that row, and then refresh you gridview by calling .databind() on it once again to that DataTable.

示例：

DataTable1.Rows(e.RowIndex).Delete()
GridView1.DataSource = DataTable1
GridView1.DataBind()
