在asp.net webforms中,我有一个带有代码隐藏文件的UserControl(如下所示)。
UserControl中有两个<asp:Label>
个节点,我试图将其用作表单中的步骤。
问题是,当我进入“Step2”并单击Cancel
时,“Step1”不会重新显示,尽管事实上我将其Visible
属性设置为true。
我做错了什么?或者有更好的方法吗?
<%@ Control Language="C#" AutoEventWireup="true"
CodeFile="MyUserControl.ascx.cs" Inherits="_MyUserControl" %>
<asp:Label runat="server" ID="lblStep1" Visible="true">
<fieldset>
<p>Some initial text here</p>
<asp:Button runat="server" CssClass="btn btn-primary" ID="cmdSubmit" Text="Submit" />
</fieldset>
</asp:Label>
<asp:Label runat="server" ID="lblStep2" Visible="false">
<p>Some text here</p>
<div>
<asp:Button runat="server" CssClass="btn btn-primary" ID="cmdRequest" Text="Send The Request" />
<asp:Button runat="server" CssClass="btn" ID="cmdCancel" Text="Cancel" />
</div>
</asp:Label>
public partial class _MyUserControl : UserControl
{
protected void Page_Init(object sender, EventArgs e)
{
cmdCancel.Click += new EventHandler(cmdCancel_Click);
cmdSubmit.Click += new EventHandler(cmdSubmit_Click);
}
public void cmdSubmit_Click(object sender, EventArgs e)
{
lblStep1.Visible = false;
lblStep2.Visible = true;
}
public void cmdCancel_Click(object sender, EventArgs e)
{
// return to the previous step
lblStep1.Visible = true;
lblStep2.Visible = false;
}
}
答案 0 :(得分:2)
你没有对那些labels
做任何事情,并且在标签控件中定义按钮是错误的想法。看起来你正在尝试使用label作为容器控件。而是使用<div>
元素/标记作为容器并尝试。它应该工作。
<div runat="server" ID="lblStep1" Visible="true">
<fieldset>
<p>Some initial text here</p>
<asp:Button runat="server" CssClass="btn btn-primary" ID="cmdSubmit" Text="Submit" />
</fieldset>
</div>
<div runat="server" ID="lblStep2" Visible="false">
<p>Some text here</p>
<div>
<asp:Button runat="server" CssClass="btn btn-primary" ID="cmdRequest" Text="Send The Request" />
<asp:Button runat="server" CssClass="btn" ID="cmdCancel" Text="Cancel" />
</div>
</div>
