Question

c# 怎么取得Repeater中文本框的值

前台:
<asp:Repeater ID="Repeater1" runat="server">
<ItemTemplate>
车种:<asp:TextBox ID="TextBox1" runat="server" Text='<%# Eval("chezhong").ToString() %>'></asp:TextBox>
<br/>
车型:<asp:TextBox ID="TextBox2" runat="server" Text='<%# Eval("chexing").ToString() %>'></asp:TextBox><br />
</ItemTemplate>
</asp:Repeater>

后台:
protected void Button1_Click(object sender, EventArgs e)
{
string str = "";
str +=((TextBox)Repeater1.FindControl("TextBox1")).Text.Trim();
str+= "-"
str +=((TextBox)Repeater1.FindControl("TextBox2")).Text.Trim();
Response.Write(str);
}
错误是为将对象引用到实例

Answer 1

foreach (RepeaterItem ri in this.Repeater1.Items)
{
if (ri.ItemType != ListItemType.Header && ri.ItemType != ListItemType.Footer)
{
TextBox box = ri.FindControl("TextBox1") as TextBox;
TextBox box1 = ri.FindControl("TextBox2") as TextBox;
str1 = box.Text.Trim();
str2 = box1.Text.Trim();
}
}

Answer 2

Repeater1.Items[0].FindControl("TextBox1")

items..需要。

另外未将对象引用实例， .trim()如果text为空也会产生这种异常。

Answer 3

string str = "";
str +=((TextBox)((Button)sender).Parent.FindControl("TextBox1")).Text

Answer 4

Repeat1.后面好像要又Items【】吧！？？？？

Answer 5

item 用这个就行
