    POST Thread: DirectMethod(). Why do postback the all page ?

    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.

    Best Regards

    Hello and welcome to the forum,

    The example you've provided cannot be run as-is and I noticed you are referring to non Ext.Net components, too. It would be great if you could provide a small but functional sample. Meanwhile, here is some piece of advice:




    Hope it helps.
