Hello Forum: I'm really wondering why any Direct Method must be calling from
any part of the page make a postback. I'm adding an example from my programming.

<javascript>
 function openVincular(Tipo) {
 document.getElementById("hfEstadoVinMapa").value = Tipo;
 App.direct.OpenVentanaVincular(Tipo);
 }
 </javascript>

 <Html>
 <asp:ImageButton id="ibVincularFicha" runat="server" ImageUrl="Images/MapasGeo/09.png" BorderStyle="Outset" OnClientClick="openVincular(1); return false;" BorderWidth="1px" ToolTip="Fichas Vincular" BorderColor="White" ></asp:ImageButton>
 </Html>

 <ServerSide>
 <DirectMethod()> _
 Public Sub OpenVentanaVincular(ByVal tipo As Integer)
 Me.Cargar_UnidadesVin()
 Me.cboGestionvin.Clear()
 Me.cboFicMod.Store.Clear()
 Me.txtDescripcionFichas.Text = ""
 Me.cboFicMod.Clear()
 Me.storeFicMod.RemoveAll()
 Me.grvListaFichasVin.ClearContent()
 Me.Window7.Show()
 Ext.Net.X.Js.AddScript("App.Window7.alignTo(Ext.ge tBody(), 'tl', [90, 150]); App.Window7.expand();")
 End Sub
 </ServerSide>
By the way, even with ext.net Button does the same results.

 <Ext.Net Buttom>
 <ext:Button ID="btProcesar" runat="server"
 Text="Procesar"
 Icon="PaintbrushColor" >
 <ToolTips>
 <ext:ToolTip runat="server" ID="ttProcesar" Title="Procesar Clasificación" Width="125" TitleAlign="Center"></ext:ToolTip>
 </ToolTips>
 <DirectEvents>
 <Click OnEvent="LlenarItemsClass" Timeout="100000" Before="Ext.Msg.wait('Procesando datos...', 'Agregando clasificaciones');" Failure="Ext.Msg.hide();" >
 </Click>
 </DirectEvents> 
 </ext:Button>
 </Ext.Net Buttom>
Please, I need any way for not make a postback. Why, I need this because I have a MapControl,
and this working with postback if one feature map is hard to load for first time, this direct
method reload again. And I trying to figure it out why ext.net makes a postback a "windows"
is not necessary for reload the whole page.
