Hello,

I've developed custom webpart for edit external database. I used LinqDataSource for connect to database and custom DataSource in web.config. When I try edit row in Grid, page is postback and edited data is actualize from db but no Update changes.

If I placed my code to separate page out from Kentico. Everything goes good...

Here is code of my webpart:

    <asp:GridView ID="gridSites" runat="server" DataSourceID="dsSites" AutoGenerateColumns="false"
        DataKeyNames="ID">
        <Columns>
            <asp:BoundField DataField="ID" HeaderText="ID" />
            <asp:BoundField DataField="Name" HeaderText="Name" />
            <asp:BoundField DataField="UrlForReplace" HeaderText="UrlForReplace" />
            <asp:TemplateField HeaderText="Provider">
                <ItemTemplate>
                    <%# Eval("Provider.Name") %>
                </ItemTemplate>
                <EditItemTemplate>
                    <asp:DropDownList ID="ddProvider" runat="server" DataSourceID="dsProviders" DataValueField="ID"
                        DataTextField="Name">
                    </asp:DropDownList>
                    <asp:LinqDataSource ID="dsProviders" runat="server" ContextTypeName="FlinkerDataDefinitionDataContext"
                        EntityTypeName="" TableName="Providers">
                    </asp:LinqDataSource>
                </EditItemTemplate>
            </asp:TemplateField>
            <asp:BoundField DataField="SiteParameter" HeaderText="SiteParameter" />
            <asp:CheckBoxField DataField="ReplaceUrl" HeaderText="ReplaceUrl" />
            <asp:CommandField ShowEditButton="True" ShowDeleteButton="true" CancelText="Zpět"
                EditText="Upravit" UpdateText="Uložit" HeaderStyle-Width="150px" />
        </Columns>
    </asp:GridView>
    <asp:LinqDataSource ID="dsSites" runat="server" ContextTypeName="FlinkerDataDefinitionDataContext"
        EntityTypeName="" TableName="Sites" EnableUpdate="true">
    </asp:LinqDataSource>

Please help me...
Thank you David
