Question

正如标题中所写，我试图从DetailsView中获取文本框值。但是，文本框值不在DetailsView中的Binded数据的内容中，因此当我尝试使用OnCommand方法获取文本时，我收到HttpContext错误。其次，我无法使用其ID来获取值，可能是因为它在DetailsView中。最后，当我将文本框和按钮放在DetailsView之外时，我得到了值，但是如果没有要在DetailsView中显示的数据，则按钮和文本不会显示。

这是我的DetailsView代码：

<asp:DetailsView ID="dvÜrün" runat="server" GridLines="None" CssClass="table table-borderless" AutoGenerateRows="false" OnCommand="dvÜrün_ItemCommand">

    <Fields>
        <asp:TemplateField Visible="false">
            <ItemTemplate>
                <%#Eval("ÜrünID") %> TL                                    
            </ItemTemplate>
        </asp:TemplateField>
        <asp:BoundField DataField="ÜrünAdı" HeaderText="Adı" />
        <asp:BoundField DataField="ÜrünKategori" HeaderText="Kategori" />
        <asp:BoundField DataField="ÜrünAçıklama" HeaderText="Açıklama" />
        <asp:TemplateField HeaderText="Ücret">
            <ItemTemplate>
                <%#Eval("ÜrünÜcret") %> TL                                    
            </ItemTemplate>
        </asp:TemplateField>
        <asp:TemplateField>                
            <ItemTemplate>
                Adet:
                <asp:textbox ID="Adet" runat="server" CssClass="text-center" textmode="SingleLine" type="number" min="1" max="20" Text="1"/>
                <asp:Button CssClass="pull-right btn btn-success" Text="Sepete Ekle" runat="server" OnClick="sepeteEkle_Click"/> 
            </ItemTemplate>
        </asp:TemplateField>
    </Fields>
</asp:DetailsView>

发布后，我立即找到答案。这是我的cs代码：

public void dvÜrün_ItemCommand(object sender, DetailsViewCommandEventArgs e)
    {
        if (e.CommandName == "ürünEkle")
        {
            string adet = ((TextBox)dvÜrün.FindControl("Adet")).Text;

        }
    }

这是DetailsView代码：

<asp:DetailsView ID="dvÜrün" runat="server" GridLines="None" CssClass="table table-borderless" AutoGenerateRows="false" OnItemCommand="dvÜrün_ItemCommand">

    <Fields>
        <asp:TemplateField Visible="false">
            <ItemTemplate>
                <%#Eval("ÜrünID") %> TL                                    
            </ItemTemplate>
        </asp:TemplateField>
        <asp:BoundField DataField="ÜrünAdı" HeaderText="Adı" />
        <asp:BoundField DataField="ÜrünKategori" HeaderText="Kategori" />
        <asp:BoundField DataField="ÜrünAçıklama" HeaderText="Açıklama" />
        <asp:TemplateField HeaderText="Ücret">
            <ItemTemplate>
                <%#Eval("ÜrünÜcret") %> TL                                    
            </ItemTemplate>
        </asp:TemplateField>
        <asp:TemplateField>                
            <ItemTemplate>
                Adet:
                <asp:textbox id="Adet" runat="server" CssClass="text-center" textmode="SingleLine" type="number" min="1" max="20" Text="1"/>
                <asp:Button CssClass="pull-right btn btn-success" Text="Sepete Ekle" runat="server" CommandName="ürünEkle"/> 
            </ItemTemplate>
        </asp:TemplateField>
    </Fields>
</asp:DetailsView>

单击ASP.NET从DetailsViews中获取文本框值并单击按钮;该文本框数据独立于绑定数据
