C# 为什么我的ASPxGridView显示的是空行，而不是我提供的值？

在描述问题之前，我想声明我已经在DevEx上提交了一个票证，但我也希望从堆栈溢出中获得更快的响应

问题：

我从动态数据表填充这个ASPxGridView。我遇到的问题是字段为空，但显示的行数正确。调试时，如果进入

dataTable.Rows[0].itemArray

属性，则可以看到正确的值。在这个过程中，我有没有遗漏一个步骤

代码如下：

void BuildEmployeeTable ()
    {
        DataTable dataTable = new DataTable();
        dataTable.Columns.Add("Employee");
        dataTable.Columns.Add("Pending");
        dataTable.Columns.Add("Investigating");
        dataTable.Columns.Add("Assigned");
        dataTable.Columns.Add("CompletedA");
        dataTable.Columns.Add("CompletedS");
        dataTable.Columns.Add("PastDueA");
        dataTable.Columns.Add("PastDueS");
        dataTable.Columns.Add("NotAccepted");

        kaizenSet.EMPLOYEEDataTable dt = GetEmployees();

        foreach (DataRow dr in dt)
        {
            string name = Security.FormatName(dr["NAME"].ToString());
            DataRow new_row = dataTable.NewRow();

            new_row["Employee"] = name;
            new_row["Pending"] = Kaizen_Queries.SubmittedKaizens(new DateTime(DateTime.Today.Year, DateTime.Today.Month, 1), new DateTime(DateTime.Today.Year, DateTime.Today.Month + 1, 1), name);
            new_row["Investigating"] = Kaizen_Queries.InvestigatingKaizens(new DateTime(DateTime.Today.Year, DateTime.Today.Month, 1), new DateTime(DateTime.Today.Year, DateTime.Today.Month + 1, 1), name);
            new_row["Assigned"] = Kaizen_Queries.InProgressKaizens(new DateTime(DateTime.Today.Year, DateTime.Today.Month, 1), new DateTime(DateTime.Today.Year, DateTime.Today.Month + 1, 1), name);
            new_row["CompletedA"] = 0;
            new_row["CompletedS"] = Kaizen_Queries.CompletedKaizens(new DateTime(DateTime.Today.Year, DateTime.Today.Month, 1), new DateTime(DateTime.Today.Year, DateTime.Today.Month + 1, 1), name);
            new_row["PastDueS"] = Kaizen_Queries.PastDueKaizens(new DateTime(DateTime.Today.Year, DateTime.Today.Month, 1), new DateTime(DateTime.Today.Year, DateTime.Today.Month + 1, 1), name);
            new_row["PastDueA"] = 0;
            new_row["NotAccepted"] = Kaizen_Queries.NotAcceptedKaizens(new DateTime(DateTime.Today.Year, DateTime.Today.Month, 1), new DateTime(DateTime.Today.Year, DateTime.Today.Month + 1, 1), name);

            dataTable.Rows.Add(new_row);
        }

        gridEmployees.DataSource = dataTable;
        gridEmployees.DataBind();
    }

您忘记在ASPxGridView定义中指定

字段名。
如果需要，FieldName必须是datatable列名或属性名
已分配集合数据源

修改标记，如下所示：

<dx:ASPxGridView ID="gridEmployees" runat="server" AutoGenerateColumns="False" OnLoad="gridEmployees_Load" Width="100%">
    <SettingsAdaptivity>
    <AdaptiveDetailLayoutProperties ColCount="1"></AdaptiveDetailLayoutProperties>
