ViewState not working during OnRefreshData event

[asztern]

Hello,

I'm trying to persist some data in the ViewState during the OnRefreshData event from the Store object.
I've changed the ViewStateMode property of the store to Enabled and the EnabledViewState to true.

Can somebody help to understand what is wrong?

Here is the code

    protected void stItems_RefreshData(object source, EventArgs e)
    {
        if (X.IsAjaxRequest)
        {
            if (ViewState[kVS_Statistics] == null)
                ViewState[kVS_Statistics] = GetKPI().Values;

            stItems.DataSource = (SortedDictionary<string, MonthLoad>.ValueCollection)ViewState[kVS_Statistics];
            stItems.DataBind();
        }
    }

<ext:Store ID="stItems" runat="server" GroupField="Employee" AutoLoad="true" OnRefreshData="stItems_RefreshData" ViewStateMode="Enabled" EnableViewState="true">
            <Proxy>
                <ext:PageProxy />
            </Proxy>
            <SortInfo Direction="DESC" Field="Period" />
            <Reader>
                <ext:JsonReader IDProperty="ID">
                    <Fields>
                        <ext:RecordField Name="Employee" />
                        <ext:RecordField Name="Period" />
                        <ext:RecordField Name="EstimatedHours" Type="Float" />
                        <ext:RecordField Name="WorkedHours" Type="Float" />
                        <ext:RecordField Name="Performance" Type="Float" />
                        <ext:RecordField Name="BugsPreRelease" Type="Int" />
                        <ext:RecordField Name="BugsPostRelease" Type="Int" />
                        <ext:RecordField Name="SupportHours" Type="Float" />
                        <ext:RecordField Name="ProjectLoadSummary" />
                    </Fields>
                </ext:JsonReader>
            </Reader>
        </ext:Store>

Thanks,
Ariel

I'm in the same situation, i have the code below, butthe viewstate doesn't persist between refreshdata's:

<ext:Store ID="_strTipoDeLogradouro" runat="server" AutoLoad="false" EnableViewState="true" OnRefreshData="_strTipoDeLogradouro_RefreshData">
        <Proxy>
            <ext:PageProxy />
        </Proxy>
        <AutoLoadParams>
            <ext:Parameter Name="inicio" Value="0" Mode="Raw" />
            <ext:Parameter Name="fim" Value="10" Mode="Raw" />
        </AutoLoadParams>
        <Reader>
            <ext:JsonReader IDProperty="ID">
                <Fields>
                    <ext:RecordField Name="ID" Mapping="ID" Type="Int" />
                    <ext:RecordField Name="Nome" Mapping="Nome" Type="String" />
                </Fields>
            </ext:JsonReader>
        </Reader>
        <Listeners>
            <LoadException Handler="Ext.Msg.alert('Employees - Load failed', e.message || response.statusText);" />
        </Listeners>
    </ext:Store>

Hi,

Please add the following code to the store

<DirectEventConfig ViewStateMode="Enabled" />
