有关动态设置System.Web.UI.WebControls.TextBox的Text的绑定

chenhaipeng 2003-07-30 08:56:39
在WebForm中用以下的代码绑定Text属性, 数据老是出不来:
TextBox1.Attributes.Add("Text","<%# DataBinderee.Eval(dataSet11, \"Tables[Employees].DefaultView.[0].FirstName\") %>");
TextBox1.DataBind();
请教正确的绑定方法!

谢谢!

to snowjin78(方圆):
不知你说的reaptear是不是Repeater, 但是Repeater里面也不能放TextBox呀

各位大哥:
下面是从设计器里面的DataBindings属性中绑定好, 生成的Html代码, 我只是想用Server端的代码实现它而已:
<asp:textbox id="TextBox1" style="Z-INDEX: 102; LEFT: 120px; POSITION: absolute; TOP: 48px" runat="server" Text='<%# DataBinder.Eval(dataSet11, "Tables[Employees].DefaultView.[0].FirstName") %>'></asp:textbox>

请注意Text属性:Text='<%# DataBinder.Eval(dataSet11, "Tables[Employees].DefaultView.[0].FirstName") %>'
这个东西只有静态可以设, 动态就不能设?

TextBox1.Text = dataset11.Tables[Employees].Rows[0]["FirstName"].tostring;

to 楼主:
如果你想绑定数据库中的数据到TextBox,可以把这个TextBox放到一个datalist或reaptear里面。因为TextBox自己不能绑定数据库,而在数据绑定组建里面可以通过设定他的Text=‘<%# DataBinderee.Eval()%》’来实现。

不懂你说的什么意思
在后台TextBox1.Text = dataset11.Tables[Employees].Rows[0]["FirstName"];
就可以得到了。

你绑的也不对啊,你要分清服务器端代码与客户端代码

Try
dad.SelectCommand = New OleDbCommand("select * from location where residentid=" + CStr(rid), con)
dad.Fill(dst, "location")
dtb = dst.Tables("location")
If dtb.Rows.Count = 1 Then
drow = dtb.Rows(0)
section.Text = drow("section")
ward.Text = drow("ward")
room.Text = drow("room")
bed.Text = drow("bed")

End If
Catch io As Exception
Response.Write(io.ToString())

End Try

错了,应该是
TextBox1.Text = dataset11.Tables[Employees].Rows[0]["FirstName"];

为什么要这样绑定呢?
TextBox1.Text = dataset11.Tables[Employees].Rows[0]FirstName;
就可以了

特别说明请注意: 根许多网友反应, using Maticsoft.Functions; 这些代码看不懂 其实Functions 这个dll是我定义常用的函数类,如果需要跟我联系索取http://sql8.net 下面有我的群号, 其中 ArtsShop.Model.Arts_Product _p = new ArtsShop.Model.Arts_Product(); ArtsShop.BLL.Arts_Product p = new ArtsShop.BLL.Arts_Product(); _p = p.GetModel(id); 这是我的商品信息的类,三层结构,这个在用时你们只能换成你们自己的,这些代码完全可以删除, 比如 MyDr[1] = _p.Title; 用来读取商品名的,你们可以改MyDr[1] = dr["productname"].ToString();就行了, AddToCart.aspx页面代码 无标题页 TextBox ID="TextBox1" runat="server" Text='' Width="44px"> Text=''> 保存 取消 编辑 继续购物 清空购物车 下订单 AddToCart.aspx.cs页面代码 using System;
