I am creating a visual web part that displays the site owners of a SharePoint site and each site owner's email. I would like users to be able to click the email address, and this will open up a new email window in Outlook.

How can you do this in C#?

This is the code I have:

(It does not contain any code that links the email addresses to Outlook yet).

namespace DisplaySiteOwnersVWP.VisualWebPart1
public partial class VisualWebPart1 : WebPart

string mySiteURL = "my Site URL goes here";
DataTable dtTable = new DataTable();

public VisualWebPart1()

protected override void OnInit(EventArgs e)

protected void Page_Load(object sender, EventArgs e)

    dtTable.Columns.Add(new DataColumn("Name"));
    dtTable.Columns.Add(new DataColumn("UserID"));
    dtTable.Columns.Add(new DataColumn("Email"));

    using (SPSite site = new SPSite(mySiteURL))
        using (SPWeb web = site.RootWeb)
            SPGroup ownerGroup = web.AssociatedOwnerGroup;
            if (ownerGroup != null)
                foreach (SPUser user in ownerGroup.Users)

                        DataRow dtRow = dtTable.NewRow();
                        dtRow["Name"] = user.Name;
                        dtRow["UserID"] = user.LoginName.Substring(6);
                        dtRow["Email"] = user.Email;


            gvOwners.DataSource = dtTable;




Make a standard web link in the format mailto:user@domain.com

  • I'm having trouble figuring out how to make the email a link to click on. I know that the code "System.Diagnostics.Process.Start("mailto:xxx@xxx.com");" will open a new email in outlook. But I do not know how to link this to the email address so that when it is clicked, the new Outlook email pops up. – Mischa Jul 2 '14 at 15:21

I figured out how to do it. I added a column like this:

<asp:TemplateField HeaderText=" " SortExpression="EmailAdress">
      <asp:TextBox ID="txtEmailAddress" runat="server" Text='<%# Bind("EmailAddress") %>'></asp:TextBox>

      <asp:HyperLink ID="HyperLink1" runat="server" NavigateUrl='<%# Eval("EmailAddress" , "mailto:{0}") %>'
                Text="Click here to email"></asp:HyperLink>
