我在一页上有多个网格视图。对于每个gridview，有两种方法可以插入一条新记录。一种是在gridview 有数据时通过TemplateField 的FooterTemplate，另一种是在gridview 为空时通过EmptyDataTemplate。

就其本身而言，插入物工作良好。但是，如果另一个 gridview 为空，则默认情况下，将显示其 EmptyDataTemplate 中的插入部分。显示此内容时，我无法显示另一个 gridview 的 FooterTemplate。在我通过强制插入摆脱 EmptyDataTemplate 之前，该部分是不可访问的。

    <asp:Button ID="btnInsertEmpty" runat="Server" Text="Insert" CommandName="EmptyInsert" UseSubmitBehavior="False" />
    </EmptyDataTemplate>        
</asp:GridView>

后面的代码：

    protected void addNewDomSoilType(object sender, EventArgs e)
    {
        gvDomSoilType.ShowFooter = true;
    }

    protected void addNewVegCover(object sender, EventArgs e)
    {
        gvVegCover.ShowFooter = true;
    }

我知道我的解释有点混乱。让我知道什么没有意义，我会尽力澄清。感谢您的关注。

这两个网格视图不应相互影响。我认为可能是 PostBack 搞砸了网页的状态。在 PageLoad 上执行 Page.IsPostBack false 然后填充数据。确保事件连接到正确的 GridView。
