I just have a basic editable grid with EditMode of EditForms.

All of the validation works for each item but I would like a rad modal pop up notification of the summary or even a message saying some fields are not correct.

I have tried several example from the forums with no luck. I've added it on itemcreated, and manully, and even above the grid.  Just does not seem to work.

A typical column looks like this:

<telerik:GridTemplateColumn HeaderText="*Address" UniqueName="address" DataField="address"
                                Display="false">
                                <ItemTemplate>
                                    <asp:Label ID="lbladdress" runat="server" Text='<%# Eval("address") %>'></asp:Label>
                                </ItemTemplate>
                                <EditItemTemplate>
                                    <telerik:RadTextBox ID="txbaddress" Width="300px" runat="server"
                                        Text='<%# Eval("address") %>'>
                                    </telerik:RadTextBox>
                                    <asp:RequiredFieldValidator ID="RequiredFieldValidator_address" runat="server" ControlToValidate="txbaddress"
                                        ErrorMessage="Required" Text="*"></asp:RequiredFieldValidator>
                                </EditItemTemplate>
                                <ItemStyle VerticalAlign="Top"></ItemStyle>
                            </telerik:GridTemplateColumn>

help would be great!

Hello Marty,

Thank you for contacting us.

In order to achieve the desired goal you can include a ValidationSummary control on the page and place it inside a modal popup or RadWindow. Once this is done you will need to show the popup/RadWindow when update is triggered and the validation fails.

In attachments you can find a sample website that I have assembled for you to review. It illustrates a possible realization of such a scenario and seems to behave as expected on my end. Please examine the implementation, try applying the same approach on your end and let us know if further questions regarding this matter arise.

Regards,
