RadGrid FormTemplate(EditFormType="Template") - CheckBox's value is not saved

[Shukhrat Nekbaev]

Hi! I'm using latest controls. I have user control loaded dynamically, it has RadGrid, which has DataSourceID set to LLBLGen datasources, automatic operations are enabled. For editing purposes I use:

<EditFormSettings InsertCaption="Add new item" CaptionFormatString="Edit Order: {0}" CaptionDataField="CustomerIdPk" PopUpSettings-Modal="true" EditFormType="Template">
            <EditColumn UniqueName="EditCommandColumn1"></EditColumn>
             <FormTemplate>
...
.....
<asp:TextBox ID="txtDescription" runat="server" Width="210px" Text='<%# Bind("Description") %>'></asp:TextBox>
<asp:DropDownList ID="ddlPaymentMethod" DataSourceID="odsPaymentMethod" SelectedValue='<%# Bind("PaymentMethod") %>' runat="server">
</asp:DropDownList>

Problem starts with this:
    <asp:CheckBox ID="chkVATApplied" Checked='<%# Bind("VATApplied") %>' runat="server" />
<telerik:RadNumericTextBox ID="txtFinalOrderPrice" runat="server"
                                     DbValue='<%# Bind("FinalOrderPrice") %>' EnabledStyle-HorizontalAlign="Center"
                                     EmptyMessage="Required" MaxValue="100000" MinValue="0"
                                     Width="80px"
                                     Type="Currency">
                                     <NumberFormat AllowRounding="false" />
                                 </telerik:RadNumericTextBox>
                                 <asp:RequiredFieldValidator ID="RequiredFieldValidator3" runat="server"
                                     ControlToValidate="txtFinalOrderPrice" Display="None"
                                     ErrorMessage="Total order price must be defined"> </asp:RequiredFieldValidator>
-------------
When I click update data is saved only from TextBoxes, DropDownList, but not from CheckBox and RadNumericTextBox. I can see that all data was loaded, but not everything is saved. Could you please hint what am I doing wrong, thank you!

Hi, any ideas on that?

Hello Shukhrat,

I looked through your code and I cannot see an obvious reason for the described issue.
Please send me the declaration of the data source and the code for the update command,so that I can advise you further.

Sincerely yours,
Mira

Hello Shukhrat,

Could you please try updating an asp:GridView with the same data source and let me know whether it  works for the boolean values.

I am looking forward to your reply.

Hi, thanks for reply, I did following, I took my control (see above) and in the beginning of it added new RadGrid and below it GridView, binded both to same datasource. Nothing at all(!) is updatable using RadGrid and everything(!) is updatable using GridView:

Hello Shukhrat,

The described behavior seems like a bug.
It will be highly appreciated if you open a formal support ticket/bug report and send us the a small working project, demonstrating the issue. Our developers will debug it locally and find out the cause of the problem.

I am looking forward to your reply.

Best wishes,
