Use Parameter. For example:

<ext:Button ID="Button1" runat="server" Text="In Bo co">
    <DirectEvents>
        <Click OnEvent="Button1_Click" >
            <EventMask ShowMask="true" />
            <ExtraParams>
                <ext:Parameter
                       Name="Values"
                       Value="Ext.encode(#{GridPanel1}.getRowsValues({selectedOnly:true}))"
                       Mode="Raw" />
            </ExtraParams>
        </Click>
    </DirectEvents>
</ext:Button>

Server code:

    protected void Button1_Click(object sender, DirectEventArgs e)
    {
        RowSelectionModel sm = this.GridPanel1.SelectionModel.Primary as RowSelectionModel;

        string data = e.ExtraParams["Values"];
        JsonObject[] jObjAr = JSON.Deserialize<JsonObject[]>(data);

        foreach (JsonObject o in jObjAr)
        {
            // Do something
        }

    }

Good luck!
