将 DataTable 绑定到 DetailsView 控件

发布于 2024-11-19 16:40:56 字数 280 浏览 2 评论 0原文

我有一个 DetailsView 控件，我想用数据表填充该控件。我在后面的代码中执行此操作。检查数据表创建成功后，代码是：

  detailsView.DataSource = dataTable;
    detailsView.DataBind();

我运行程序，但详细信息视图没有显示。问题是否是数据表可能有多行，而详细信息视图只有一行？如果这就是问题，有办法解决吗？我在创建数据表时确保它只有一行。我还尝试仅绑定数据表中的一行，但不接受数据表行作为数据源。有什么问题吗？

I have a DetailsView control that I want to populate with a data table. I'm doing this in code behind. After checking that the data table is created successfully, the code is:

  detailsView.DataSource = dataTable;
    detailsView.DataBind();

I run the program and the detailsView doesn't show.Could the problem be that a data table potentially can have multiple rows and a details view only one? If that's the problem is there a way of getting around it? I made sure in creating the data table that it has only one row. I also tried binding only one row in the data table but a data table row isn't accepted as a data source. What's the problem?

您必须添加绑定字段或设置DetailsView AutoGenerateRows="true"才能在详细信息视图中显示该字段。我确信你忘记这样做了..

 <asp:DetailsView ID="DetailsView1" runat="server" Height="50px" Width="125px" >
        <Fields>
            <asp:BoundField DataField="FieldName" HeaderText="Field Title" />
            .......................
            .......................
        </Fields>
    </asp:DetailsView>

You have to add in a Bound field or Set the DetailsView AutoGenerateRows="true" to display the field in the detailsView. I am sure you forget to do this..

 <asp:DetailsView ID="DetailsView1" runat="server" Height="50px" Width="125px" >
        <Fields>
            <asp:BoundField DataField="FieldName" HeaderText="Field Title" />
            .......................
            .......................
        </Fields>
    </asp:DetailsView>
