Hi ,

I have created sample please refer the below code.

HTML

<asp:FormView ID="FormView1" runat="server" DefaultMode="Edit" Width="1200px">
    <EditItemTemplate>
        <table class="style1">
            <tr>
                <td>
                    <asp:Button ID="btnEdit" Text="Edit" runat="server" OnClick="EditClick" />
                </td>
            </tr>
            <tr>

    if (FormView1.CurrentMode == FormViewMode.Edit)
    {
        TextBox tb = (TextBox)FormView1.Row.Cells[0].FindControl("TextBox1");
        tb.Focus();
        Page.MaintainScrollPositionOnPostBack = true;
    }
