Question

I have a Asp:Hyperlink in aspx page and i am setting the text and navigation url dynamically but when page renders it adds the relative path of my website in the rendered href. i dont know why?

ASPX

<asp:HyperLink runat="server" ID="charityNameText"></asp:HyperLink>

CODE-BEHIND (Page Load Event)

//Getting data from database

charityNameText.Text = entryDetails.RegisteredCharityName;
charityNameText.NavigateUrl = "www.facebook.com";
charityNameText.Target = "_blank";

Rendered HTML

<a id="ctl00_PageContent_CompetitionsEntries_ctl06_charityNameText" href="../../ConLib/Custom/www.facebook.com" target="_blank">save the childrens</a>


../../ConLib/Custom/ is the path where this file is located.

There are different solutions for your case. My best approach would be using the System.UriBuilder class.

String myUrl = "www.facebook.com";
UriBuilder builder = new UriBuilder(myUrl);
charityNameText.NavigateUrl = builder.Uri.AbsoluteUri;

The UriBuilder adds the protocol (HTTP) in your case to the URL you are loading and initializes an instance of the Uri class with the complete URL. Use the AbsoluteUri property.

For more complex cases you can use Regex :

        String myUrl = "www.facebook.com";
        System.Text.RegularExpressions.Regex url = new System.Text.RegularExpressions.Regex(@"/^(https?:\/\/)?([\da-z\.-]+)\.([a-z\.]{2,6})([\/\w \.-]*)*\/?$/", System.Text.RegularExpressions.RegexOptions.IgnoreCase);

        System.Text.RegularExpressions.MatchCollection matches = url.Matches(myUrl);

        foreach (System.Text.RegularExpressions.Match match in matches)
        {
            string matchedUrl = match.Groups["url"].Value;
            Uri uri = new UriBuilder(matchedUrl).Uri;
            myUrl = myUrl.Replace(matchedUrl, uri.AbsoluteUri);
        }

i will try this... BUT i am using HyperLink in many of pages and i am using response.redirect and does not seems any issue with those. is it because i am using the data from database.

YES..... I used the simple approach of building the URL by using UriBuilder and everything is working as expected...

You have to add the protocol to the beginning of the URL: http://wwww.facebook.com
