You can truncate the description text like follows:

ASP.NET

<asp:Label id="Label6" runat="server" text='<%# Eval("description") != null ? TruncateText(Eval("description").ToString(), 200) : string.Empty %>'></asp:Label>

TruncateText(Eval("description").ToString(), 200) displays first 200 characters of the description text.

C#

public string TruncateText(string inputText, int length)
{
	if (inputText.Length <= length)
		return inputText;

	var delimiters = new[] { ' ', '.', ',', ':', ';' };
	var index = inputText.LastIndexOfAny(delimiters, length - 3);

	if (index > (length / 2))
		return inputText.Substring(0, index) + "...";

	return inputText.Substring(0, length - 3) + "...";
}
