I think the problem is with your Validator Control, when you are assigning the control name to ControlToValidate="ddlcustomer" property, you should take care, because there will not be any control named ddlcustomer at runtime, so the control's cliendID should be assigned to validator's ControlToValidate ptoperty, which you can do in row_databound event of your gridview, find the validator and say textbox control with FindControl method and assign the clintId of your textbox to validator's property.

mark as answer if solved ur problem.

I would recommend changing the

XML

<asp:CommandField ShowEditButton="true" ButtonType="Button" />

to a template field and set the validationGroup to your name on the edit template fields. See below

XML

<asp:TemplateField ShowHeader="False">
                <EditItemTemplate>
                    <asp:LinkButton ID="lbUpdate" runat="server" CausesValidation="True"
                        CommandName="Update" Text="Update" ValidationGroup="EditrowValidation"></asp:LinkButton>
                    &nbsp;<asp:LinkButton ID="lbCancel" runat="server" CausesValidation="False"
                        CommandName="Cancel" Text="Cancel"></asp:LinkButton>
                </EditItemTemplate>
                <ItemTemplate>
                    <asp:LinkButton ID="lbEdit" runat="server" CausesValidation="False"
                        CommandName="Edit" Text="Edit"></asp:LinkButton>
                </ItemTemplate>
            </asp:TemplateField>
