    Access url from a Toolbar Menu

    Hello,

    I need to access a URL from a Toolbar Menu

    I'm doing the following:

    Dim MenuNivelItem As MenuItem = New MenuItem()

MenuNivelItem.DirectEvents.Click.Url = Trim(cnxNivelItem.drListagem(7).ToString())
    The error message returned is:

    Application Server Error in '/ Prj-Studies'.

    Validation of Viewstate MAC failed. If this application is hosted on a Web farm or cluster, ensure that configuration specifies the same <machineKey> same validationKey and validation algorithm. AutoGenerate can not be used in a cluster.

    Note: the URL captured from the database is "page.aspx"

    Has anyone experienced this?

    Thanks

    Hi danilo,

    Please clarify what are you trying to achieve? What does "I need to access a URL" mean?

    I want to open a url in the click of a MenuItem ()

    realized two unsuccessful attempts

    1. MenuNivelItem.DirectEvents.Click.Url = "https://examples1.ext.net"

    2. MenuNivelItem.PostBackUrl = "https://examples1.ext.net"

    what could be wrong?

    Thanks!

    Hi danilo,

    Please look at the example.

    Example
    <%@ Page Language="C#" %>

<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>

<script runat="server">
    protected void LoadExtNet(object sender, DirectEventArgs e)
    {
        Window1.AutoLoad.Url = "http://ext.net";
        Window1.AutoLoad.Mode = LoadMode.IFrame;
        Window1.AutoLoad.ShowMask = true;
        Window1.Render();
    }

    protected void LoadGoogle(object sender, DirectEventArgs e)
    {
        Window1.AutoLoad.Url = "http://google.com";
        Window1.AutoLoad.Mode = LoadMode.IFrame;
        Window1.AutoLoad.ShowMask = true;
        Window1.Render();
    }
</script>
