    How to enable view state for direct event?

    Hi,

    Here is my code:

    <asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent">
    <ext:ResourceManager runat="server" ViewStateMode="Enabled" />
    <ext:FormPanel EnableViewState="true" ViewStateMode="Enabled" runat="server">
        <Buttons>
            <ext:Button ID="SendUserName" Text="Send" runat="server" >
                <DirectEvents>
                    <Click OnEvent="SendUserName_DirectClick" />
                </DirectEvents>
            </ext:Button>
        </Buttons>
        <Items>
            <ext:HBoxLayout runat="server">
                <BoxItems>
                    <ext:BoxItem>
                        <ext:TextField ID="UserName" runat="server" />
                    </ext:BoxItem>
                    <ext:BoxItem>
                        <ext:Label ID="InfoLabel" runat="server" Text="" />
                        </ext:BoxItem>
                </BoxItems>
            </ext:HBoxLayout>
        </Items>
    </ext:FormPanel>
</asp:Content>
        public partial class _Default : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
        }

        protected void SendUserName_DirectClick(object sender, DirectEventArgs e)
        {
            InfoLabel.Text = "User name set: " + (UserName.Text ?? "(no info)");
        }
    }
    My problem: UserName.Text always equals "" (empty string). How to change this (enable view state)?

    Hi galuset,

    You can set ViewStateMode="Enabled" on the DirectEvent config.

    Example

    <Click ViewStateMode="Enabled" OnEvent="SendUserName_DirectClick" />
    Hope this helps.

    Unfortunately this didn't help :(

    Here is how my code looks like.

    <asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent">
    <ext:ResourceManager ID="ResourceManager1" runat="server" ViewStateMode="Enabled" />
    <ext:FormPanel ID="FormPanel1" EnableViewState="true" ViewStateMode="Enabled" runat="server">
        <Buttons>
            <ext:Button ID="SendUserName" Text="Send" runat="server" >
                <DirectEvents>
                    <Click ViewStateMode="Enabled" OnEvent="SendUserName_DirectClick" />
                </DirectEvents>
            </ext:Button>
        </Buttons>
        <Items>
            <ext:HBoxLayout ID="HBoxLayout1" runat="server">
                <BoxItems>
                    <ext:BoxItem>
                        <ext:TextField ID="UserName" runat="server" />
                    </ext:BoxItem>
                    <ext:BoxItem>
                        <ext:Label ID="InfoLabel" runat="server" Text="" />
                        </ext:BoxItem>
                </BoxItems>
            </ext:HBoxLayout>
        </Items>
    </ext:FormPanel>
</asp:Content>
    Maybe something is wrong with my Site.Master or Web.config...

    Site.Master
    <%@ Master Language="C#" AutoEventWireup="true" CodeBehind="Site.master.cs" Inherits="ColliteTest.SiteMaster" %>
