Question

我正在使用DetailsView仅用于插入数据，用于选择，更新和删除我使用Gridview。因此，当表中没有数据时，我没有看到插入新数据的文本框，如何解决这个问题？任何帮助表示赞赏！

DetailsView代码

 <asp:DetailsView ID="DetailsView1" runat="server" Height="50px" Width="125px" DefaultMode="Insert" OnItemInserted= "Inserted" 
              AutoGenerateInsertButton="True" CellPadding="4" DataKeyNames="Name, Software, License Number" AutoGenerateRows="true" 
              DataSourceID="AccessDataSource1" ForeColor="#333333" 
        GridLines="None">
              <FooterStyle BackColor="#5D7B9D" Font-Bold="True" ForeColor="White" />
              <CommandRowStyle BackColor="#E2DED6" Font-Bold="True" />
              <RowStyle BackColor="#F7F6F3" ForeColor="#333333" />
