Dotnetnuke ASP.NET中的ParseControl将onclick更改为javascript而不是提供的c#方法，奇怪的行为 [英] ParseControl in Dotnetnuke ASP.NET changing onclick to javascript instead of c# method provided, strange behavior

问题描述

这里有一些奇怪的行为.我有一些XSLT，它会生成带有一些ASP.NET链接按钮控件的html

Having some strange behavior here. I have some XSLT which generates some html with a few ASP.NET Link Button Controls

 String mstring = sw.ToString();
 var myctrl = Page.ParseControl(mstring);

      foreach (Control Control in myctrl.Controls)
              {
                  if (Control is LinkButton)
                      {
                         LinkButton lb = (LinkButton)Control;
                         lb.OnClientClick = "LoadPromo";

                       }
                          Panel1.Controls.Add(myctrl);
               }  

  protected void LoadPromo(object sender, EventArgs e)
        {
            Console.Write(e.ToString());

        }

现在就可以控制了:

<asp:LinkButton ID="LinkButton2" runat="server" OnClick="LoadPromo" Text="Get your Free 2" />

并在添加事件时将其更改为此:

and changes it to this when I add an event:

<a onclick="LoadPromo;" id="dnn_ctr954_ViewPromotions_LinkButton2" href=" WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions("dnn$ctr954$ViewPromotions$LinkButton2", "", true, "", "", false, true))">Get your Free 2 a>

现在您可以看到，它将onclick更改为类似于javascript而不是asp.net控件.它将"LoadPromo"更改为"LoadPromo;".我该怎么办才能解决这个问题?

Now as you can see, it changes the onclick to like javascript instead of the asp.net control.It changes "LoadPromo" to "LoadPromo;". What can i do to get around this?

预先感谢

我尝试过的事情:

 lb.Click += LoadPromo;

我得到以下输出:

<a id="dnn_ctr954_ViewPromotions_LinkButton2" href="javascript:WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions(&quot;dnn$ctr954$ViewPromotions$LinkButton2&quot;, &quot;&quot;, true, &quot;&quot;, &quot;&quot;, false, true))">Get your Free 2</a>

推荐答案

OnClientClick是服务器控件的属性名称，该控件最终呈现为"onclick"属性.这是为了在客户端调用javascript函数.因此，在这种情况下，看起来不错.

OnClientClick is the name of the property of a server control that eventually renders to an "onclick" attribute. This is meant to invoke a javascript function on the client side. So in this case, it looks fine.

对于OnClick属性，您需要使其与Page.aspx中服务器端函数的名称匹配.我不知道为什么还要为此渲染onclick属性-也许您没有带有正确签名的名为"LoadPromo"的函数?

For the OnClick property, you need to have that match the name of a server-side function in your Page.aspx. I'm not sure why it would even be rendering the onclick attribute for this - perhaps you don't have a function named "LoadPromo" with the right signature?

您应该具有这样的C#方法:

You should have a C# method like this:

protected void LoadPromo(object sender, EventArgs e)
{

}

然后您可以通过

myLinkButton.Click += LoadPromo;
