Did you give GridView and DetailsView different ValidationGroups? And did you apply that ValidationGroup to all buttons? You will have to put all Buttons in ButtonField and set ValidationGroup on that.
If so, we'll have to hope for someone more knowledgable on validation to come by and answer.

I tried adding validation control. Unfortunately the validation control of the detailesView still try to validate the

Update event of the gridView control.

The keyword for this is ValidationGroup. I don't know all the ins and outs of it, but the idea is you link validator and that which is validated by putting them in the same ValidationGroup. When something in a group is to be validated, only that group will be validated. Things without ValidationGroup will be validated on every PostBack.

Validation control in detailsview

Hello,

I have a form with Gridview and detailsview controls that connected to the same objectdatasource.

I use the gridview to list data from the datasource as well as let the user update data. I use the detailsview to let the user Insert new data.

I converted the field of the detailsview into a template field and in the 'Insert template" I inserted a Required field validation control

and set its properties to validate the right control.

When trying to Insert empty data into the detailsview control the validation control works fine, the problem starts when

the user edit a row in the gridview control and than click the Update, in this situation the validation control of the detailsview

doesn't let the update operation to take place in the gridview control.

any ideas?

The code is -

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"
            DataKeyNames="pk" DataSourceID="ObjectDataSource1" AllowPaging="True" PageSize="5">
                <Columns>
                    <asp:CommandField ShowEditButton="True" />
                    <asp:BoundField DataField="teacher" HeaderText="teacher"
                    SortExpression="teacher" Visible="False" />
                    <asp:BoundField DataField="school" HeaderText="Class"
                    SortExpression="school" >
                        <ItemStyle Width="200px" />
                    </asp:BoundField>
                    <asp:BoundField DataField="pk" HeaderText="pk" InsertVisible="False"
                    ReadOnly="True" SortExpression="pk" Visible="False" />
                </Columns>
</asp:GridView>

<asp:DetailsView ID="DetailsView1" runat="server" AutoGenerateRows="False"
            DataKeyNames="pk" DataSourceID="ObjectDataSource1" DefaultMode="Insert"
            Height="50px" Width="221px">
                <Fields>
                    <asp:BoundField DataField="teacher" HeaderText="teacher"
                    SortExpression="teacher" Visible="False" />
                    <asp:TemplateField HeaderText="school" SortExpression="school">

                        <InsertItemTemplate>
                            <asp:TextBox ID="TextBox2" runat="server" Text='<%# Bind("school") %>'></asp:TextBox>
                            <asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server"
                                ControlToValidate="TextBox2" ErrorMessage="*">*</asp:RequiredFieldValidator>
                        </InsertItemTemplate>

                    </asp:TemplateField>
                    <asp:BoundField DataField="pk" HeaderText="pk" InsertVisible="False"
                    ReadOnly="True" SortExpression="pk" />
                    <asp:CommandField ShowInsertButton="True" />
                </Fields>
</asp:DetailsView>
