Populate FormView from Database using VB.Net in ASP.Net

Here I have created sample that full-fill your requirement.

HTML

<div>
    <asp:FormView ID="FormView1" runat="server" OnPageIndexChanging="OnPageIndexChanging"
        AllowPaging="true">
        <HeaderTemplate>
            <table border="0" cellpadding="0" cellspacing="0">
                <tr>
                    <th>
                        Customer Id
                    </th>
                    <th>
                        Name
                    </th>
                    <th>
                        Country
                    </th>
                </tr>
        </HeaderTemplate>
        <ItemTemplate>
            <tr>
                <td>
                    <%#Eval("CustomerId")%>
                </td>
                <td>
                    <%#Eval("Name")%>
                </td>
                <td>
                    <%#Eval("Country")%>
                </td>
            </tr>
        </ItemTemplate>
        <FooterTemplate>
            </table>
        </FooterTemplate>
    </asp:FormView>
</div>
