Question

asp:RadioButtonList ID="RadlContent" runat="server" AutoPostBack="true" 
                  OnSelectedIndexChanged="RadlContent_SelectedIndexChanged" 
                  RepeatDirection="Horizontal" RepeatLayout="Flow">
                  <asp:ListItem Value="99">所有</asp:ListItem>
                  <asp:ListItem Value="99">已审核</asp:ListItem>
                  <asp:ListItem Value="100">待审核</asp:ListItem>
                  <asp:ListItem Value="101">已删除</asp:ListItem>
              </asp:RadioButtonList>
protected void RadlContent_SelectedIndexChanged(object sender, EventArgs e)
     {
         int RadlContent_ID = Convert.ToInt32(RadlContent.SelectedItem.Value);
         string RadlContent_Text = RadlContent.SelectedItem.ToString();
         if (RadlContent_ID == 98) { Response.Redirect("Management_Students.aspx?ActCode=RadlContent_ID=98"); }
         if (RadlContent_ID == 99) { Response.Redirect("Management_Students.aspx?ActCode=RadlContent_ID=99"); }
         if (RadlContent_ID == 100) { Response.Redirect("Management_Students.aspx?ActCode=RadlContent_ID=100"); }
         
     }
可是不对啊！！

Answer 1

AutoPostBack="true"这个属性设置了没有``?

Answer 2

   string RadlContent_Text = RadlContent.SelectedItem.Text 

Answer 3

 if (RadlContent_ID == 98) { Response.Redirect("Management_Students.aspx?ActCode=RadlContent_ID=98"); } 
        if (RadlContent_ID == 99) { Response.Redirect("Management_Students.aspx?ActCode=RadlContent_ID=99"); } 
        if (RadlContent_ID == 100) { Response.Redirect("Management_Students.aspx?ActCode=RadlContent_ID=100"); } 
这是什么意思啊``?
ActCode=RadlContent_ID=98``?

Answer 4

RadlContent.SelectedItem.Text 取一个。如果要取多个。就要用到循环了

Answer 5

在web.config中的<pages enableViewState = "false" /> 
Response.Write(this.RadioButtonList1.SelectedItem.Value); 

Answer 6

RadlContent.SelectedItem.Text 

Answer 7

我都没得说了，RadioButtonList.SelectedIndex也是可以判断到底是哪个Item被选中了；

Answer 8

int OP_ID = Convert.ToInt32(this.RadlContent.SelectedItem.Value);OP_ID 没有值？  晕了
