String append does not work

System.Text.StringBuilder sb = new System.Text.StringBuilder();
sb.Append("javascript:openjobdetails('employer_info.aspx?SupplierId=");
sb.Append(GlobalFunctions.Encrypt(employerId.ToString()));
sb.Append("&prth_act=info");
if (!string.IsNullOrEmpty(referenceNumber))
{
sb.Append("&ref_num=");
sb.Append(referenceNumber);
}

sb.Append("')");

The last append does not work. I get the following output:
javascript:openjobdetails('employer_info.aspx?SupplierId=ODM=&prth_act=info&ref_num=PM/12

it has to work, you must have that line after using sb to get the output.

Is there anything between the last } and the last sb.Append line? I just whipped up a quick example and got the correct output.

using System;
using System.Text;

public class Program
{
	public static void Main()
	{
		string empID = "ODM";
		string refNum = "PM/12";
		StringBuilder sb = new StringBuilder();
		sb.Append("javascript:openjobdetails('employer_info.aspx?SupplierId=");
		sb.Append(empID);
		sb.Append("&prth_act=info");
		if (!string.IsNullOrEmpty(refNum))
		{
			sb.Append("&ref_num=");
			sb.Append(refNum);
		}
		sb.Append("')");
		Console.WriteLine(sb.ToString());

		// Wait for user input to close the program.
		Console.ReadLine();
	}
}

Open in new window

Produces the the following output:

public string GetCompanyLogo(object objEmployerId, object objReferenceNumber)
    {
        string strCompanyLogo = string.Empty;

        string referenceNumber = string.Empty;
        if (objReferenceNumber != null)
        {
            referenceNumber = Convert.ToString(objReferenceNumber);
        }

        if (objEmployerId != null)
        {
            int employerId = Convert.ToInt32(objEmployerId);

            List<Users> users = Users_List.SelectByID(employerId);
             if (users.Count > 0)
             {
                 String thumbCompanyLogo = users[0].ThumbCompanyLogo;

                 System.Text.StringBuilder sb = new System.Text.StringBuilder();
                 sb.Append("javascript:openjobdetails('employer_info.aspx?SupplierId=");
                 sb.Append(GlobalFunctions.Encrypt(employerId.ToString()));
                 sb.Append("&prth_act=info");
                 if (!string.IsNullOrEmpty(referenceNumber))
                 {
                     sb.Append("&ref_num=");
                     sb.Append(referenceNumber);
                 }
                 
                 sb.Append("')");

                 string href = sb.ToString();

                 string innerHtml = "<img src='images/No-logo.jpg' border='0' align='absmiddle' width='70px' title='View Details'/>";
                 if (!string.IsNullOrEmpty(thumbCompanyLogo) && File.Exists(Server.MapPath("uploadedfiles/" + thumbCompanyLogo)))
                 {
                     innerHtml = "<img src=\"uploadedfiles/" + thumbCompanyLogo + "\" border=\"0\" align=\"absmiddle\" width=\"70px\"   title=\"View Details\"/>";
                 }

                 strCompanyLogo = "<a href=" + href + ">" + innerHtml + "</a>";
             }
        }

        return strCompanyLogo;
    }

Open in new window

and the aspx file is as follows:

 <ItemTemplate>
        <tr style="font-size: medium">
            <td>
                <%# GetCompanyLogo(Eval("EmployerID"), Eval("Reference_Number")) %>

Open in new window

In the function, it returns only part of the string.

Looking at the previous comment, I think accepting that comment as the solution was a mistake.
