title: Telerik Rad window opens once only
body: <p>I have a Rad Grid with a Hyperlink in its itemTemplate, The Hyperlink will open a Radwindow</p>
  
  <pre><code>&lt;asp:Content ContentPlaceHolderID="MenuPlaceHolder" runat="server" ID="Menus"&gt;

              window.radopen("OnCar.aspx?SN=" + id, "ShowOnCar");
              return false;
          }

          &lt;/MasterTableView&gt;
      &lt;/telerik:RadGrid&gt;
  &lt;/telerik:RadAjaxPanel&gt;

      &lt;/Windows&gt;
  &lt;/telerik:RadWindowManager&gt;&lt;/asp:Content&gt;
  </code></pre>
  
  <p>in code behind, </p>
  
  <blockquote>
  <pre><code>Protected Sub dt_lst_SN_ItemDataBound(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles dt_lst_SN.ItemDataBound
      If TypeOf e.Item Is GridDataItem Then
          Dim onCarLink As HyperLink = DirectCast(e.Item.FindControl("onCarLink"), HyperLink)
          onCarLink.Attributes("href") = "#"
          onCarLink.Attributes("onclick") = [String].Format("return ShowOnCar('{0}');", e.Item.Cells(dt_lst_SN.Columns.FindByUniqueName("SN_ID").OrderIndex).Text)
      End If
  End Sub
  </code></pre>
  </blockquote>
  
  <p>This code will open the radwindow correctly but just once!
  What is missing?</p>
