I've created a helper function, that allows me to set extra CSS class name(space separated)
public static string AppendIfNotContains(string str, string sToAppend, string delimeter)
{
if (!str.Contains(sToAppend))
{
str = AppendWithDelimeter(str, sToAppend, delimeter);
}
return str;
}
public static string AppendWithDelimeter(string str, string sToAppend, string delimeter)
{
if ((!str.EndsWith(delimeter) & !String.IsNullOrEmpty(str)) & !String.IsNullOrEmpty(sToAppend))
{
str = str + delimeter;
}
str = str + sToAppend;
return str;
}
