Stringbuilder text not displaying on new lines

Question

I have a generic html control - a 'P' tag, which i've added a runat="server" to.

I construct a string using Stringbuilder methods and apply this to the InnerHtml attribute of the tag.

The text,which contains a number of sb.Appendline()'s still displays as a paragraph would, wrapping but without creating any new lines. However, When i look at the markup created, the new lines are there, shown as spacing.

This is also the case with a DIV

Anyone got any ideas as to how i fix this?

Code below:

        var sb = new StringBuilder();
        sb.Append("Congratulations!");
        sb.AppendLine();
        sb.AppendLine();
        sb.AppendFormat("Your application was accepted by <b>{0}</b>.", response.AcceptedLender);
        sb.AppendLine();
        sb.AppendFormat("Your reference number is <b>{0}</b>.", response.PPDReference);
        sb.AppendLine();
        sb.AppendLine();
        sb.Append("Click the button below to sign your loan agreement electronically and collect your cash.");

        AcceptedMessage.InnerHtml = sb.ToString();

Answer 1

Instead of using AppendLine should use AppendFormat:

myStringBuilder.AppendFormat("{0}<br />", strToAppend);

If you need these line breaks to remain "as is" because you're displaying it in a text file or something of that nature, you'll need to replace the new line text with html breaks when you're calling the .ToString() method.

myStringBuilder.Replace(Environment.NewLine, "<br />").ToString();

Using Environment.NewLine here may not work, you may actually need to replace \r\n.

Answer 2

You have to convert the stringlbuilder newlines (\n) into BR tags

so that they can be rendered in HTML newlines.

Even better IMO is to enclose the whole lines in P tags
