string from database

I am saving HTML in the database in asp.net. This is how I try to insert it into the editor. The issue is the javascript is spreading over multiple lines.

IDataReader drTemplateInfo = DataMain.GetTemplateByTemplateID(ID);
if (drTemplateInfo.Read())
{
templateVal = drTemplateInfo["templateVal"].ToString();
}
drTemplateInfo.Close();
drTemplateInfo.Dispose();
sb = new StringBuilder();
sb.Append(" <script>; ");
//sb.Append(" oEditor.FCKUndo.SaveUndoStep();");
sb.Append(" FCK.InsertHtml('" + templateVal + "');");
sb.Append(" window.parent.Cancel();");
sb.Append(" </script>; ");
Page.ClientScript.RegisterStartupScript(typeof(Page), "InfoSubmitted12", sb.ToString());
