View 2 RepliesCan someone explain to me the rules around what can and cannot be evaluated/inserted into markup using the <%# %> and <%= %> tags in asp.net?When I first discovered I could inject code-behind variables into mark-up using <%= I thought 'great'. Then I discovered that if such tags are present you can then not add to the controls collection of the page (that's a whole different question!). But <%# tags are ok.
Is there a way I can inject a code-behind variable or function evaluation into the page using <%# ?

I have 10 hyperlink controls. Depending on which hyperlink is pressed I want to pass a value to the target page. I think the easiest way would be to pass the value using URL of the hyperlink controls. Something like <asp:HyperLink ID="HyperLink1" NavigateUrl="~/News.aspx?id=>. I can pass just a value, but I want to pass a value from a variable.
<asp:HyperLink ID="HyperLink1" runat="server"

I am maintaining a website that has .Aspx web pages with no code behind C# files. This has been a challenge for me, because I need to do the following:
1.) When the page first loads, display a Java Script popup message box.
So how can I do this if I don not have a code behind C# file where I can check for isPostback in the on page load method? Can the on page load method be placed inline in the .aspx code? Anyway I need to figure out how to answer my question 1 above.
Im wonding what the correct syntax is to pass 2 parameters from a Ascx control into a Vb.net function? Heres what I currently have:
<asp:Literal
ID="CommentFooterLiteral1"
Visible='<%# Eval("Approved") Or IsModerator() %>'
Text='<%# FormatFooter(Eval("Anonymous"), Eval("DisplayName"), Eval("CreatedDate")) + "
" + GetModeratorStatus(Eval("UserId")) %>'
runat="server"
/>
The Function "FormatFooter", needs to pass in Anonymous and DisplayName parameters. Anyone know the correct syntax for doing this?

I want to test this code found here. It allows me to auto-load content from server as the user scrolls down the scroll down. I am having difficulties trying to convert code to C#/ASP.NET. Primarily, I want this code to be translated to C#/ASP.NET:
package com.vraa.demo;
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class InfinitContentServlet extends HttpServlet {
private static Integer counter = 1;
protected void processRequest(HttpServletRequest request,
HttpServletResponse response) throws ServletException, IOException {
PrintWriter out = response.getWriter();
try {
String resp = "";
for (int i = 1; i <= 10; i++) {
resp += "<p><span>"
+ counter++
+ "</span> This is the dynamic content served freshly from server</p>";
}
out.write(resp);
} finally {
out.close();
}
}
@Override
protected void doGet(HttpServletRequest request,
HttpServletResponse response) throws ServletException, IOException {
processRequest(request, response);
}
@Override
protected void doPost(HttpServletRequest request,
HttpServletResponse response) throws ServletException, IOException {
processRequest(request, response);
}
}
In addition, I would like to know if I have to make any changes to this JavaScript code:
<script type="text/javascript">
$(document).ready(function(){
$contentLoadTriggered = false;
$("#content-box").scroll(function(){
if($("#content-box").scrollTop() >= ($("#content-wrapper").height() - $("#content-box").height()) && $contentLoadTriggered == false)
{
$contentLoadTriggered = true;
$.get("infinitContentServlet", function(data){
$("#content-wrapper").append(data);
$contentLoadTriggered = false;
});
}
});
});
</script>
