Question

我有以下gridview。没有错误，但是当我使用w3c验证器验证页面并且不存在任何行时，colspan属性获取gridview中已定义列数量的值。我们有可能在没有行的情况下使gridview删除colspan属性吗？

 <asp:GridView ID="gv1" AutoGenerateColumns="False" ShowFooter="true" runat="server"
        AllowSorting="true" AllowPaging="true" CssClass="gridview" OnDataBound="gv_DataBound"
        OnRowDataBound="gv_RowDataBound" DataKeyNames="id" CellSpacing="-1" GridLines="None"
        EmptyDataText="no reference substances linked!">
        <Columns>
            <asp:HyperLinkField DataTextField="name" HeaderText="reference substance" DataNavigateUrlFormatString="~/ReferenceSubstances/{0}.aspx"
                DataTextFormatString="{0}" Target="_self" DataNavigateUrlFields="id" SortExpression="name" />
            <asp:BoundField DataField="supplier" HeaderText="supplier" SortExpression="supplier" />
            <asp:BoundField DataField="supplier_code" HeaderText="supplier code" SortExpression="supplier_code" />
            <asp:BoundField DataField="lot" HeaderText="lot" SortExpression="lot" />
        </Columns>
        <PagerStyle CssClass="footer" />
        <PagerTemplate>
            <asp:GridViewPager ID="GridViewPager1" runat="server" />
        </PagerTemplate>
    </asp:GridView>

Answer 1

听起来你需要一个EmptyDataTemplate：

<asp:GridView ...
   <EmptyDataTemplate>
      render any markup
   </EmptyDataTemplate>
</asp:GridView>

将render any markup替换为任何兼容w3c的标记。

试试这个

 <asp:GridView ID="gv1" AutoGenerateColumns="False" ShowFooter="true" runat="server"
        AllowSorting="true" AllowPaging="true" CssClass="gridview" OnDataBound="gv_DataBound"
        OnRowDataBound="gv_RowDataBound" DataKeyNames="id" CellSpacing="-1" GridLines="None"
>
     <EmptyDataTemplate>
                                    no reference substances linked!
                                </EmptyDataTemplate>
        <Columns>
            <asp:HyperLinkField DataTextField="name" HeaderText="reference substance" DataNavigateUrlFormatString="~/ReferenceSubstances/{0}.aspx"
                DataTextFormatString="{0}" Target="_self" DataNavigateUrlFields="id" SortExpression="name" />
            <asp:BoundField DataField="supplier" HeaderText="supplier" SortExpression="supplier" />
            <asp:BoundField DataField="supplier_code" HeaderText="supplier code" SortExpression="supplier_code" />
            <asp:BoundField DataField="lot" HeaderText="lot" SortExpression="lot" />
        </Columns>
        <PagerStyle CssClass="footer" />
        <PagerTemplate>
            <asp:GridViewPager ID="GridViewPager1" runat="server" />
        </PagerTemplate>
    </asp:GridView>

Answer 3

请添加ShowHeaderWhenEmpty =“true”属性以显示emptydatatext，而gridview没有记录。对不起，如果这不是你要求

<asp:GridView ID="gv1" ShowHeaderWhenEmpty="true" etc

asp：GridView EmptyData行有错误的colspan
