问题描述

我的页面包含:
1-文本框.
一键式.

Hi,

My page contains:
1-TextBox.
1-Button.
2-Place Holder.

I have 3 WebUsersControls which contain many controls.

What I need is, when enter 1 in the TextBox for example, and then click button, load the first WebUserControl in the PlaceHolder, Then if I entered 2 in the TextBox load the second WebUserControl in the PlaceHolder, without removing first one.

Thank You

推荐答案

页面指令

<%@ Register Src="controls/wuc1.ascx" TagName="control1" TagPrefix="ucq" %>
<%@ Register Src="controls/wuc2.ascx" TagName="control2" TagPrefix="ucq" %>
<%@ Register Src="controls/wuc3.ascx" TagName="control3" TagPrefix="ucq" %>

在页面正文中(占位符):

within page body(Place Holder):

<ucq:control1 id="control1"  runat="server"  />
<ucq:control2 id="control2"  runat="server" />
<ucq:control3 id="control3"  runat="server" />

背后的代码

Code behind

protected void Page_Load(object sender, EventArgs e)
  {
      if (!Page.IsPostBack)
      {
        control1.Visible=false;
        control2.Visible=false;
        control3.Visible=false;
      }
  }
protected void btnCommand_Click(object sender, EventArgs e)
  {
  if(!string.IsNullOrEmpty(textbox1.text))
      {
        if(textbox1.text.tostring()=="1")
             control1.Visible=true;
        if(textbox1.text.tostring()=="2")
             control2.Visible=true;
        if(textbox1.text.tostring()=="3")
             control3.Visible=true;
      }
   }

但是，如果可以使用javascript会更好.
让我知道您的反馈.

But if you can do using javascript that will be better.
Let me know your feedback.

我建​​议您将用户控件放在div中，并先将它们设置为隐藏，然后根据需要使用JavaScript显示.

I would suggest placing the user controls in divs and setting them initially as hidden, then displaying them as necessary with JavaScript.

我不知道将显示多少WebUserControl和哪些命令的问题.

The problem that I don''t know how many WebUserControl will display and which orders.
