Question

gridview 怎样删除一行

我绑定的数据源是数据库，在GRIDVIEW中显示两个字段（studentNO,studentName)，我在网上看了上，要获取主键值，高手给写一个细点的protected void D1_SelectedIndexChanged(object sender, EventArgs e)化码，我就五分了，

Answer 1

源代码
<asp:GridView ID="GridView2" runat="server" DataSourceID="SqlDataSource1" DataKeyNames="typeid"
AutoGenerateColumns="False" AllowSorting="True" AllowPaging="True" AutoGenerateEditButton="True"
Width="483px" OnRowUpdating="GridView2_RowUpdating" OnRowDataBound="GridView2_RowDataBound"
OnRowDeleting="GridView2_RowDeleting" OnRowCommand="GridView2_RowCommand">

DataKeyNames是你的主键

后台代码
protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
co = new common(); //数据库链接类
string sql = "Delete from [dbo].[T-InvestItem] where id='" + GridView1.DataKeys[e.RowIndex].Value + "'";
co.Sql_ExecuteSql(sql);
}

Answer 2

直接用GridView提供的删除按钮操作
只要在数据源里设定一下DeleteCommand语句就ok了

Answer 3

不是用这个事件的！
删除用GridView1_RowDeleting事件!
