Answer 1

网页的B/S 还是C/S的，我只有网页获取 该行数据的值 LINKBUTTON 传值
a.aspx

<asp:Label ID="Label2" runat="server" Text="Label"></asp:Label></td>

<asp:GridView ID="GridView1" runat="server"
DataKeyNames="cid" CellPadding="4" ForeColor="#333333" GridLines="None" >
<RowStyle BackColor="#EFF3FB" />
<Columns>
<asp:BoundField DataField="cid" HeaderText="课程号" ReadOnly="True"
SortExpression="cid" />
<asp:BoundField DataField="cname" HeaderText="课程名" SortExpression="cname" />
<asp:BoundField DataField="credit" HeaderText="学分"
SortExpression="credit" />
<asp:BoundField DataField="hour" HeaderText="课时" SortExpression="hour" />
<asp:TemplateField><ItemTemplate>
<asp:LinkButton ID="LinkButton1" runat="server" OnCommand="click" CommandArgument='<%#eval_r("cid")%>'>
选课</asp:LinkButton>
</ItemTemplate></asp:TemplateField>
</Columns>
</asp:GridView>

在a.aspx.cs中进行接收：

protected void click(object sender, CommandEventArgs e)
{
int id = int.Parse((string)e.CommandArgument);
string cid = id.ToString().Trim();

// this.ClientScript.RegisterStartupScript(this.GetType(), "", "<script>alert(' "+cid+"')</script>");

Label2.Text = cid;
}

当点击后，就可以看到 Label2.Text的值改变了

此时获得的这个参加就可以对数据库进行操作了。

private void gridview_CellContentClick(object sender, DataGridViewCellEventArgs e)
{
int index = e.ColumnIndex;
if (index == 2 && e.RowIndex != -1)
{
string str1 = gridview.CurrentRow.Cells[0].Value.ToString().Trim();
string str2= gridview.CurrentRow.Cells[1].Value.ToString().Trim();
}
