如何将Div id作为参数传递给C＃函数？

Question

I've created a div with an id and i want to activate a function (code behind) with the div id when someone click on the div . help please?

Project .aspx.cs

        HtmlGenericControl Div1 = new HtmlGenericControl("div");
        Div1.Attributes.Add("class", "ProjectItem");
        Div1.Attributes.Add("id", p.groupCode);
        Div1.Attributes.Add("runat", "server");

Answer 1

您需要阅读有关DIV的runat="server"标签的信息

Answer 2

A nice way of doing it is adding a hidden server button to your page.

<asp:Button runat="server" id="btnPostback" style="display:none" onclick="serverEventHandler" />

And then add this to your div init:

Div1.Attributes.Add("onclick","document.getElementById('" + btnPostback.ClientID + "').click()");

And then add this to your code behind:

protected void serverEventHandler(object sender, EventArgs e)
{
  // Put code here
}

EDIT:
I don't see any proper way of sending the Div id, but you can change the hidden button's text to the Div id and then read it on the click event:

Div1.Attributes.Add("onclick","document.getElementById('" + btnPostback.ClientID + "').value='Div1';document.getElementById('" + btnPostback.ClientID + "').click()");

And the click event:

protected void serverEventHandler(object sender, EventArgs e)
{
   string div_id=btnPostback.Text;
}
