求教关于ASP.NET(C#)DetailView控件添加FileUpload控件实现图片上传的问题
我在DetailsView里启用了【插入】功能，并添加了一个ImageField然后将它转换成模板，
再在它的InsertItemTemplate里面添加了一个FileUpload控件和一个Button按钮。
我想实现的是当我点击Button按钮时上传选择的图片，并把上传图片的路径（固定为：【~/UserImage/】）
和图片名，即以【~/UserImage/22.jpg】格式赋值到UserImage所对应的TextBox中，
(DetailsView里面当点击新建时弹出的那个插入页面里面各项对应的都是TextBox控件)，当点击自带的插入时保存到数据库中。
这个功能该怎么做啊？
我的数据库字段是：Id(主键 int 自增) , UserName , UserImage(存储图片的路径和图片名,即【~/UserImage/22.jpg】格式), Telephone
我的代码如下：

--------------------编程问答-------------------- 这个问题解决了吗 我现在也面临这个问题呢 我的后台管理商品界面上用的detailview绑定的数据，但是用的插入功能 怎么能够结合用fileupload上传图片？我现在是手动修改路径而不是选择路径
protected void Button1_Click(object sender, EventArgs e)
{
string ii = (DetailsView1.FindControl("Label1") as Label).Text;
string ii2 = (DetailsView1.FindControl("FileUpload1") as FileUpload).FileName;
ii = "~/UserImage/"+ii2;
string ii3 = (DetailsView1.FindControl("Label2") as Label).Text;
ii3 = ii;
}
补充：.NET技术 , ASP.NET
