Question

有没有办法在不知道字段名称的情况下显示ListView？在后面的代码中，我将数据传递给ListView，但不知道如何显示它，因为我打算将这个模板用于我的所有表。

在模板中

<tr>
    foreach( Key in ListView.Keys )
    {
        <th>Key</th>
    }
</tr>
foreach( Row in LisView.Rows )
{
    <tr>
        foreach ( Column in Row )
            <td>Column</td>
    </tr>
}

输出示例：

----------------------------
| id  | name    | surname  |
----------------------------
| 1   | John    | Doe      |
| 2   | Jack    | Jones    |
| 3   | Mary    | Williams |
| 4   | Sue     | Smith    |

任何帮助表示赞赏！提前谢谢！

Answer 1

这解决了我的问题：

HTML

<asp:PlaceHolder ID = "PlaceHolder1" runat="server" />

命名空间

using System.Data;
using System.Text;
using System.Configuration;
using System.Data.SqlClient;

代码

    //Populating a DataTable from database.
    DataTable dt = this.GetData();

    //Building an HTML string.
    StringBuilder html = new StringBuilder();

    //Table start.
    html.Append("<table border = '1'>");

    //Building the Header row.
    html.Append("<tr>");
    foreach (DataColumn column in dt.Columns)
    {
        html.Append("<th>");
        html.Append(column.ColumnName);
        html.Append("</th>");
    }
    html.Append("</tr>");

    //Building the Data rows.
    foreach (DataRow row in dt.Rows)
    {
        html.Append("<tr>");
        foreach (DataColumn column in dt.Columns)
        {
            html.Append("<td>");
           html.Append(row[column.ColumnName]);
            html.Append("</td>");
        }
        html.Append("</tr>");
    }

    //Table end.
    html.Append("</table>");

    //Append the HTML string to Placeholder.
    PlaceHolder1.Controls.Add(new Literal { Text = html.ToString() });

找到更好的方法：

HTML

<asp:Table ID="testTable" runat="server" />

代码

            TableRow tHeaderRow = new TableHeaderRow();

            tHeaderRow.TableSection = TableRowSection.TableHeader;

            testTable.Rows.Add(tHeaderRow);

            foreach (DataColumn column in all("Users").Columns)
            {
                TableHeaderCell tHeaderCell = new TableHeaderCell();
                tHeaderCell.Text = column.ColumnName;
                tHeaderRow.Cells.Add(tHeaderCell);
            }

            foreach( DataRow row in all("Users").Rows)
            {
                TableRow tRow = new TableRow();

                testTable.Rows.Add(tRow);

                foreach (DataColumn column in all("Users").Columns)
                {
                    TableCell tCell = new TableCell();
                    tCell.Text = row[column.ColumnName].ToString();
                    tRow.Cells.Add(tCell);
                }
            }

我的all("Users")函数返回DataTable

动态显示ListView
