    [CLOSED] Failed to load viewstate

    I get this error when I select item from the dropdown. I breaks before to go to the code behind 

    Failed to load viewstate.  The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request.  For example, when adding controls dynamically, the controls added during a post-back must match the type and position of the controls added during the initial request.

    RE: [CLOSED] Failed to load viewstate

    Hi,

    The information is not enough. I believe that you have dynamic controls which you doesn't recreate during DirectEvent (or create another instead controls which were created initialy)


    Please post full test sample

    RE: [CLOSED] Failed to load viewstate

    I was trying to create delegate event. It always comes as null. do you have an idea

    <%@ Control Language="C#" AutoEventWireup="true" CodeBehind="getnametest.ascx.cs" Inherits="test.scripts.getnametest" %>

<%@ Register assembly="Ext.Net" namespace="Ext.Net" tagprefix="ext" %>

<script runat="server">

public delegate void ItemSelectedEventHandler(string id);

protected void Page_Load(object sender, EventArgs e)
{
    if (!X.IsAjaxRequest)
    {
        this.Button1.Text = string.Concat("UserControl (", this.Name, ")");
    }
}

public event ItemSelectedEventHandler test25;

[DirectMethod]
public void GetName()
{
    if (test25 != null)
    {
        X.Msg.Alert("Name", this.Name).Show();
    }
}

public string Name
{
    get;
    set;
}
</script>
<ext:Button ID="Button1" runat="server" Text="test">
    <Listeners>
    <   Click Handler="#{DirectMethods}.GetName();" />
    </Listeners>
</ext:Button>

    Hi sharif,

    Please do not include the .dlls in any attachments.


    As well, adding [CODE] tags around your code samples will help with formatting.
