ASP.NET - asp:hyperlink window properties

I have an asp.net page with repeater. inside it I have a item template. I have a Hyper link :

 <asp:HyperLink ID="hpErrorDetails" runat="server" Visible="false" onclick="myWindow=window.open('/','','width=200,height=100;toolbar=no')">Details ...</asp:HyperLink>

Inside C# : 

I have this:

 hpErrorDetails.NavigateUrl = string.Format("automatedtesterror.aspx?id={0}", automatedTestRun.AutomatedTestRunId);

I want to open in new window and want that newly opened window is without toolbar and  scrollbar. but I m getting error.

 <asp:HyperLink ID="hpErrorDetails" runat="server" Visible="false" NavigateUrl="#">Details ...</asp:HyperLink>

In C# (Code Behinnd)


hpErrorDetails.Attributes.Add("onclick","myWindow=window.open('"+string.Format("automatedtesterror.aspx?id={0}", automatedTestRun.AutomatedTestRunId+"','','width=200,height=100;toolbar=no')");

I tried this code. It opens two windows. one for JavaScript and one using asp.net.

  <asp:HyperLink ID="hpErrorDetails" runat="server" Visible="false" NavigateUrl="#">Details ...</asp:HyperLink>

 hpErrorDetails.Attributes.Add("onclick","myWindow=window.open('"+string.Format("automatedtesterror.aspx?id={0}", automatedTestRun.AutomatedTestRunId+"','','width=500,height=500;toolbar=no')"));
