我做了一对男女的单选框 我选了男 的确显示出了性别男。。但是我选性别女时。。。单选框男的那个还在.
我想写个if判断那样可以解决...但是我在想..是否能从page_load这方面来想...
而且我还想请高手讲哈子ispostback 这个东东..!
Default.aspx.cs
using System.Configuration;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
Male.Checked = false;
Female.Checked = false;
Message.Text = " ";
}
}
protected void submit_Click(object sender, EventArgs e)
{
if (Male.Checked)
{
Message.Text = "男";
}
if (Female.Checked)
{
Message.Text = "女";
}
}
}
