为什么我的ASPxGridView显示空白行而不是我提供的值？

Question

在对问题进行描述之前，我想说明我已经在DevEx上提交了一张票证，但我也希望能从堆栈溢出中得到更快的响应。

问题：

我正在从一个动态的ASPxGridView中填充这个DataTable。我遇到的问题是字段是空的，但是正确的行数显示。调试时，如果进入dataTable.Rows[0].itemArray属性，就可以看到正确的值。在这个过程中，我有可能遗漏了什么步骤吗？

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();
    }

Answer 1

您忘记在FieldName定义中指定ASPxGridView。如果指定集合数据源，则FieldName必须是datatable列名或属性名。

修改标记如下：

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

    <EditFormLayoutProperties ColCount="1"></EditFormLayoutProperties>
    <Columns>
        <dx:GridViewDataTextColumn Name="Name" FieldName="Employee" Caption="Name" VisibleIndex="0">
        </dx:GridViewDataTextColumn>
        <dx:GridViewDataTextColumn Name="Pending" FieldName="Pending" Caption="Pending" VisibleIndex="1">
        </dx:GridViewDataTextColumn>
        <dx:GridViewDataTextColumn Name="Investigating" FieldName="Investigating" Caption="Investigating" VisibleIndex="2">
        </dx:GridViewDataTextColumn>
        <dx:GridViewDataTextColumn Name="Assigned" FieldName="Assigned" Caption="Assigned" VisibleIndex="3">
        </dx:GridViewDataTextColumn>
        <dx:GridViewDataTextColumn Name="CompleteA" FieldName="CompleteA" Caption="Complete (Assigned)" VisibleIndex="4">
        </dx:GridViewDataTextColumn>
        <dx:GridViewDataTextColumn Name="CompleteS" FieldName="CompleteS" Caption="Complete (Submitted)" VisibleIndex="5">
        </dx:GridViewDataTextColumn>
        <dx:GridViewDataTextColumn Name="PastDueA" FieldName="PastDueA" Caption="Past Due (Assigned)" VisibleIndex="6">
        </dx:GridViewDataTextColumn>
        <dx:GridViewDataTextColumn Name="PastDueS" FieldName="PastDueS" Caption="Past Due (Submitted)" VisibleIndex="7">
        </dx:GridViewDataTextColumn>
        <dx:GridViewDataTextColumn Name="NotAccepted" FieldName="NotAccepted"  Caption="Not Accepted" VisibleIndex="8">
        </dx:GridViewDataTextColumn>
    </Columns>
</dx:ASPxGridView>
