Un required validation error alert Within Grid view

Question

i have a grid view which is used both for editing and inserting data .. 1)in order to insert data i use Footer rows. 2) and to edit data i use rest of the rows. the problem is that when ever i am trying to update any of the row with in grid view, the footer row validation also gets alert, which i dont want .. i want that only selected row validation should remain active ...

My Grid View Code is:

 <asp:GridView ID="PanelDetGridView" CssClass="table col-12 table-bordered table-hover widget-box widget-title widget-content nopadding" runat="server" AutoGenerateColumns="false" ShowFooter="true" OnRowCancelingEdit="PanelDetGridView_RowCancelingEdit" OnRowCommand="PanelDetGridView_RowCommand" OnRowDeleting="PanelDetGridView_RowDeleting" OnRowEditing="PanelDetGridView_RowEditing" OnRowUpdated="PanelDetGridView_RowUpdated" OnRowUpdating="PanelDetGridView_RowUpdating">

Answer 1

something like this

 <asp:RequiredFieldValidator ID="RequiredFieldValidator17" CssClass="error"      ControlToValidate="txtSmalloc" ValidationGroup="CodataValidation" Display="Dynamic" runat="server" ErrorMessage="something" />

 <FooterTemplate>
 <asp:LinkButton ID="lnkAdd" runat="server" CausesValidation="True" ValidationGroup="CodataValidation" CommandName="Insert" Text="Insert"></asp:LinkButton>
 </FooterTemplate>

Answer 2

Add a seperate validationgroup.

Both actions now validate the same validators.
