When a user inputs certain special characters i.e a html tag, the user receives this:

Error loading Partial View script (file: ~/Views/MacroPartials/ezSearch.cshtml)

I have been investigating and this seems to be a common issue and I attempted to apply a fix so it would strip out 'bad' characters:

    public string CleanseSearchTerm(string input)
{
    System.Text.RegularExpressions.Regex rgx = new System.Text.RegularExpressions.Regex("[^a-zA-Z0-9 -]");
    input = rgx.Replace(input, "");

    return input.ToString();
}

However, the issue is that this error is getting generated before it has a chance to hit my method to strip out 'bad' characters. Any ideas of how this can be resolved?
