Hi Ismail,

You could create a new inline method to effectively override the PrintNodeName one? Like so...

<%@ Control Language="c#" AutoEventWireup="True" Codebehind="LatestEdits.ascx.cs" Inherits="dashboardUtilities.LatestEdits" TargetSchema="http://schemas.microsoft.com/intellisense/ie5" %>
<link href="/umbraco_client/propertypane/style.css" rel="stylesheet" />

<script runat="server">
    public string PrintLine(object nodeId, object date, object userId)
    {
        var nodeName = PrintNodeName(nodeId, date);

        int id;
        if (int.TryParse(userId.ToString(), out id) && !string.IsNullOrWhiteSpace(nodeName))
        {
            var user = umbraco.BusinessLogic.User.GetUser(id);
            if (user != null)
            {
                return string.Format("{0} by {1} <br/>", nodeName.Replace("<br/>", string.Empty), user.Name);
            }
        }

        return nodeName;
    }
</script>

<asp:Repeater id="Repeater1" runat="server">
    <HeaderTemplate>
    <div class="propertypane">
        <div class="guiDialogNormal" style="margin: 10px">
        <h2><%=umbraco.ui.Text("defaultdialogs", "lastEdited")%>:</h2>
    </HeaderTemplate>

    <ItemTemplate>
        <%# PrintLine(DataBinder.Eval(Container.DataItem, "NodeId"), DataBinder.Eval(Container.DataItem, "datestamp"), DataBinder.Eval(Container.DataItem, "userId")) %>
    </ItemTemplate>

    <FooterTemplate>
        </div>
    </div>
    </FooterTemplate>

</asp:Repeater>

You could extend it to only display currently logged in user - umbraco.BusinessLogic.User.GetCurrent()

Enjoy!  (Keep in mind that upgrades will overwrite this!)

Cheers, Lee.
