Yes you could create a new datatype which does this. Here is an example to get you started (with the usercontrol wrapper):

<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="HyperLinkView.ascx.cs" Inherits="WebApplication.DataTypes.HyperLinkView.HyperLinkView" %>
<asp:HyperLink ID="HplClick" runat="server"></asp:HyperLink>

public partial class HyperLinkView : UserControl, umbraco.editorControls.userControlGrapper.IUsercontrolDataEditor
{
    #region IUsercontrolDataEditor Members

    public object value
    {
        get
        {
            return HplClick.NavigateUrl;
        }
        set
        {
            if ((value != null) && (!string.IsNullOrEmpty(value.ToString())))
            {
                HplClick.NavigateUrl = value.ToString();
                HplClick.Text = value.ToString();
                HplClick.Target = "_blank";
            }
        }
    }

    #endregion

    protected void Page_Load(object sender, EventArgs e)
    {

    }
}

This is a bit like the label datatype, but as a hyperlink.

I'm kind of new on the usercontrol thingy.
Any guide onto where or how should I start?

Thanks  

It is really simple. Jeroen has already posted the code you need. You then only to copy the DLL containing the codebehind into the "bin" folder of your installation and the *.ascx file into the "usercontrols" folder of your installation.

In the umbraco backend navigate to the developer section, right click on the "Data Types" folder and create a new datatype. Selection the "umbraco usercontrol wrapper" as Property editor. Save the data type and the select your deployed ASCX file from the usercontrol dropdown. Save again and you have successfully created your first own data type.

Be sure to also select the correct database datatype and ensure value object you return maps this datatype.

Managed to get it working. Another thing for the below, how do I get the value of the "Link to document"
to be used below? (the parts below with the comment)

Thanks

publicpartialclassHyperLinkView:UserControl, umbraco.editorControls.userControlGrapper.IUsercontrolDataEditor
{
    #region IUsercontrolDataEditor Members

    publicobject value
    {
        get
        {
            returnHplClick.NavigateUrl;
        }
        set
        {
            if((value !=null)&&(!string.IsNullOrEmpty(value.ToString())))
            {
                HplClick.NavigateUrl= value.ToString();
                HplClick.Text= value.ToString();
                HplClick.Target="_blank";
            }
        }
    }

    #endregion

    protectedvoidPage_Load(object sender,EventArgs e)
    {
value = "/TestTemplate/"; // how do I get the value of the 'Link to document' here to concat with the "/TestTemplate/"?
    }
}

I suggest to override the onload method (or even page_load, but I always preferec the control specific methods) and reading the value on postback. Use a private member value to store the value in background instead of directly referencing your web control.

public YourClass : ....
{
   private int _linkValue;

    public object value
   {
      get
      {
          return _linkValue;
      }
      set
      {
          if (value != null && !string.IsNullOrEmpty(value.ToString()))
          {
             _linkValue = value.ToString();
          }
      }
   }
   
   protected override void OnLoad(EventArgs e)
   {
         if (!Page.IsPostback)
         {
               HplClick.NavigateUrl = _linkValue;
               HplClick.Text = _linkValue;
         }
         else
         {
               _linkValue = HplClick.NavigateUrl;
         }
    }
}

If this is what you want ;-)

how do I get the value from the "Link to document"?

If the node is published you could try something like this (might need to add some namespaces)

var node = new Node(Convert.ToInt32(Request.Querystring["id"]));
var linkToDocument = node.Url;

Jeroen

The below error came out

Error2The type or namespace name 'Node' could not be found (are you missing a using directive or an assembly reference?)

You need to add a reference to the umbraco.dll file and than Visual Studio can resolve it for you.

Jeroen

Kind of new in this thing, how can I add a reference to the umbraco.dll file in Visual Studio?

This video might help :) http://umbraco.com/help-and-support/video-tutorials/introduction-to-umbraco/developer-introduction/using-net-user-controls/TVPlayer

Jeroen

I suggest using the nuget package manager. And the run Install-Package UmbracoCms.Core

Verify to get the correct version you are corrently deploying to.

still can't figure out how to get it work.

any other way that I can get the CurrentPage's Url in the .ascx.cs file?

You'll need the reference to the umbraco.dll file which is in the /bin folder of you website. Maybe this can help: http://msdn.microsoft.com/en-us/library/wkze6zky(v=vs.80).aspx

good news, managed to get it all sorted out :)
