Question

.net(C#)单击Repeater中的Button,ItemCommand事件

前台代码：

<asp:Repeater ID="Repeater1" runat="server" DataSourceID="SqlDataSource1" OnItemCommand="Repeater1_ItemCommand">
<ItemTemplate>
<div>
<asp:Label ID="Label1" runat="server" Text='<%# Eval("TemplateName")%>'></asp:Label>
<asp:HiddenField ID="HiddenField1" runat="server" Value='<%# Eval("ID")%>' />
<asp:Button ID="Button1" runat="server" Text="Button" />
</div>
</ItemTemplate>
</asp:Repeater>
<p><asp:Label ID="Label2" runat="server" Text="Label"></asp:Label></p>

后台代码：

protected void Page_Load(object sender, EventArgs e)
{

}

protected void Repeater1_ItemCommand(object source, RepeaterCommandEventArgs e)
{

Label2.Text = "";
}

如何实现每次点击 Repeater中的Button ，把HiddenField 的值赋值给Label2 呢？

Answer 1

150343376 - 助理 二级 思路正确，但太粗心。
HiddenField h = (HiddenField)e.Item.FindControl("HiddenField1");
Label2.Text = h.Value;

Answer 2

protected void Repeater1_ItemCommand(object source, RepeaterCommandEventArgs e)
{
HiddenField hidden = (HiddenField)e.Item.FindControl("HiddenField1");
Label2.Text = hidden .Value;
}

Answer 3

HiddenField hf=(HiddenField)e.item.finfcontrol("HiddenField1")
this.label1.text=hf.text;

Answer 4

直接绑定也可以吧
