取得DataList中控件的值
点击按钮时将datalist控件中的值取出来提交，现在的问题是能取到datalist里面的控件但是不能取到控件的值。调试发现值是空的。 --------------------编程问答-------------------- 贴下代码看看 --------------------编程问答-------------------- 代码问题 --------------------编程问答-------------------- Page_Loadif(!IsPostBack)
{
//数据绑定
} --------------------编程问答-------------------- foreach (DataListItem d in dtSmallTask.Items)
{
TextBox txtSendTo1 = (TextBox)d.FindControl("txtSendTo");
string txtsendTovalue=txtSendTo1.Text;
}
发现为空值在提交前txtSendTo有内容的，注意提交的按钮并不在dtSmallTask的模板内。所以ItemCommand之类的东西没考虑。请高手指教 --------------------编程问答-------------------- 至于if (!IsPostBack)
{}这个存在的控件是找得到的但是就是取不到模板里面控件的值 --------------------编程问答--------------------
你的模版里的控件有值吗？
用findcontrol取不到？
demo
protected void DataList1_ItemCommand(object source, DataListCommandEventArgs e)--------------------编程问答-------------------- 回复6楼：
{
if (e.CommandSource.GetType() == typeof(Button))
{
if (((Button)e.CommandSource).CommandName == "accept")
{
if (((CheckBox)e.Item.FindControl("select")).Checked)
{
int id = Convert.ToInt32(DataList1.DataKeys[e.Item.ItemIndex].ToString());
int stuid = Convert.ToInt32(((Label)e.Item.FindControl("label1")).Text);
string stuname = ((Label)e.Item.FindControl("label2")).Text;
string stuadd = ((Label)e.Item.FindControl("label3")).Text;
SqlConnection cn = new SqlConnection(strcon);
SqlCommand cmd = new SqlCommand("insert into s(StuID,StuName,Stuaddurl) values('" + stuid + "','" + stuname + "','" + stuadd + "')", cn);
cn.Open();
cmd.ExecuteNonQuery();
SqlCommand cmd1 = new SqlCommand("delete from students where ID='" + id + "'", cn);
cmd1.ExecuteNonQuery();
cn.Close();
bind();
}
}
if (((Button)e.CommandSource).CommandName == "noaccept")
{
if (((CheckBox)e.Item.FindControl("select")).Checked)
{
int id = Convert.ToInt32(DataList1.DataKeys[e.Item.ItemIndex].ToString());
int stuid = Convert.ToInt32(((Label)e.Item.FindControl("label1")).Text);
string stuname = ((Label)e.Item.FindControl("label2")).Text;
string stuadd = ((Label)e.Item.FindControl("label3")).Text;
SqlConnection cn = new SqlConnection(strcon);
SqlCommand cmd = new SqlCommand("insert into sj(stuid,stuname,stuadd) values('" + stuid + "','" + stuname + "','" + stuadd + "')", cn);
cn.Open();
cmd.ExecuteNonQuery();
SqlCommand cmd1 = new SqlCommand("delete from students where ID='" + id + "'", cn);
cmd1.ExecuteNonQuery();
cn.Close();
bind();
}
}
}
对模板里面控件存在值。但是我提交的按钮并不在datalist这个控件里面也就是说我点击按钮的作用是循环找datalist里面控件的值并对数据进行数据库操作。至于ItemCommand事件应该是触发不到的。 --------------------编程问答-------------------- <%@ Page Language="C#" AutoEventWireup="true" EnableViewState ="false" CodeFile="Default2.aspx.cs" Inherits="Default2" %>

我看这些代码没啥问题了
控件都取不到值，还是检查下配置文件有没有做全局enableviewstate设置，并在本页面page命令加上 EnableViewState="true"
另外，其它页面没有这样的问题？ --------------------编程问答-------------------- 估计也是那样现在很久没用这块了记得之前好像都没问题的。估计还是代码里面那个地方有问题吧 --------------------编程问答-------------------- 有没有用新的母版页，模板页是否EnableViewState = "false" --------------------编程问答-------------------- 没有设置 --------------------编程问答--------------------
那就休息，明天再调试，可能豁然开朗 --------------------编程问答-------------------- 也是，但是这个东西搞不好，我就睡都睡不着。这还是头一次调试那么就居然找不到原因。那我从新写一次试下看看到底哪里有问题。 --------------------编程问答--------------------
写个原型试试 --------------------编程问答-------------------- 问题解决答案已于昨晚解决：我用的脚本对其进行datalist中的控件进行赋值，而且本身datalist中生成的控件为客户端控件所以如果在提交的时候服务器端时判断该控件的值是空的，是用脚本找到该控件对应的clientid在从中去取值。 --------------------编程问答-------------------- http://blog.csdn.net/xianfajushi/archive/2008/11/30/3413317.aspx
--------------------编程问答--------------------
取DataList中某一项中的某个控件的值，这样是吧所以项的值都取出来了！
