RadGrid in Sharepoint don't fire Insert(Edit) Command

[Adam]

Hi,
I added a RadGrid to my custom page.

<asp:UpdatePanel ChildrenAsTriggers="true" UpdateMode="Conditional" runat="server">

        <ContentTemplate>

            <telerik:RadGrid ID="rgProducts" runat="server" AutoGenerateColumns="false" Skin="WebBlue"

                OnItemInserted="rgProducts_ItemInserted" OnInsertCommand="rgProducts_InsertCommand"
      OnNeedDataSource="rgProducts_NeedDataSource" OnEditCommand="rgProducts_EditCommand"
                      OnItemUpdated="rgProducts_ItemUpdated">

                <MasterTableView CommandItemDisplay="Top" AllowAutomaticInserts="True" EditMode="InPlace">

                    <Columns>

                        <telerik:GridBoundColumn DataField="ProductId" HeaderText="Id" />

                        <telerik:GridBoundColumn DataField="ProductName" HeaderText="Name" />

                        <telerik:GridBoundColumn DataField="BuyerGroup" HeaderText="BuyerGroup" />

                        <telerik:GridEditCommandColumn EditText="Edit" CancelText="Cancel" HeaderText="" />

                    </Columns>

                </MasterTableView>

            </telerik:RadGrid>

        </ContentTemplate>

    </asp:UpdatePanel>

When Grid is in edit mode, I fill required fields and press Update button, but this only fire Load event.
The event OnNeedDataSource fire properly, but events OnInsertCommand, OnEditCommand don't.
I try to create grid programmatic, but the effect is the same.

PageLoad function:

protected void Page_Load(object sender, EventArgs e)
        {
            if (!Page.IsPostBack)
            {
                rgProducts.DataSource = OrderMoq.Products;
            }
        }

rgProducts_NeedDataSource function:

protected void rgProducts_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)
        {
            rgProducts.DataSource = OrderMoq.Products;
        }

I found the solution. It was the UpdatePanel bug in Sharepoint.
