Error: Failed to unable constraints.. ;when binding records in RadGrid

Question

下面是我使用存储过程绑定 RadGrid 的代码。我正在使用 .xsd 文件调用存储过程 - TableAdapter 方法

HTML代码：

<telerik:RadGrid ID="rgData" runat="server" ShowFooter="true"
OnNeedDataSource="rgData_NeedDataSource"
AllowSorting="True" AllowFilteringByColumn="True" ShowGroupPanel="True" GroupLoadMode="Client"
EnableEmbeddedSkins="False" ImagesPath="../App_Themes/MetroRed/Grid" Skin="MetroRed">
   <ClientSettings AllowDragToGroup="True"></ClientSettings>
   <GroupingSettings ShowUnGroupButton="false" CaseSensitive="false"></GroupingSettings>
   <MasterTableView ShowGroupFooter="true" CommandItemDisplay="None" AutoGenerateColumns="false" AllowMultiColumnSorting="true">
   <CommandItemSettings ShowAddNewRecordButton="false" />
    <Columns>
           <telerik:GridBoundColumn HeaderText="Billing ID" DataField="BillingID" SortExpression="BillingID" FilterDelay="2000" ShowFilterIcon="false">
       </telerik:GridBoundColumn>
       <telerik:GridBoundColumn HeaderText="Direct Cost" DataField="DCIDescription" SortExpression="DCIDescription" FilterDelay="2000" ShowFilterIcon="false">
       </telerik:GridBoundColumn>
           <telerik:GridBoundColumn HeaderText="Business Unit" DataField="BUName" SortExpression="BUName" FilterDelay="2000" ShowFilterIcon="false">
           </telerik:GridBoundColumn>
    </Columns>
   </MasterTableView>
</telerik:RadGrid>

C#代码：

private DataTable _dtData = null; 

protected void rgData_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)
    {
        try
        {
            _dtData = SDM.Invoice.GetInvoiceBySPID(_SPID);
            rgData.DataSource = _dtData;
        }
        catch (Exception ex)
        {
        }
    }

Class BLL文件夹内的文件：

#region Invoice
private static SDM_Invoice _Invoice = null;
public static SDM_Invoice Invoice
{
    get
    {
        if (_Invoice == null)
        _Invoice = new SDM_Invoice();
 
        return _Invoice;
    }
}
#endregion

private SDM_Tran_GenerateInvoiceTableAdapter _GenerateInvoiceTableAdapter = null;
protected SDM_Tran_GenerateInvoiceTableAdapter Adapter
{
    get
    {
        if (_GenerateInvoiceTableAdapter == null)
                _GenerateInvoiceTableAdapter = new SDM_Tran_GenerateInvoiceTableAdapter();

            return _GenerateInvoiceTableAdapter;
    }
} 
    
public SDMDAL.SDM_Tran_GenerateInvoiceDataTable GetInvoiceBySPID(string SPID)
{
    return Adapter.GetInvoiceBillingBySPID(SPID);
}

绑定 RadGrid 的存储过程：

ALTER PROCEDURE [dbo].[Select_InvoiceBillingBySPID]
    @SPID as nvarchar(50)
    AS
BEGIN

    SET NOCOUNT ON; 

SELECT 
--B.ID,
B.BillingID, 
DCIDescription,
(SELECT BUName FROM dbo.SDM_Master_BU WITH (NOLOCK) WHERE BUID=AfoBUID) as BUName

FROM SDM_Tran_Billing B WITH (NOLOCK),
dbo.SDM_Tran_DCI D WITH (NOLOCK), 
dbo.SDM_Tran_Allocation A WITH (NOLOCK)

WHERE B.BfoAllocationID=AllocationID 
and A.AfoDCIID=D.DCIID 
and D.DCIfoSPID=@SPID
and B.BfoStatusID=1

END

.xsd 文件 - Table 适配器

每当我运行我的网页时，我都会收到以下错误：

Failed to unable constraints. One or more rows contain values violating non null, unique or foreign key constraints.

我认为错误是因为我在存储过程中使用 3 个不同的表（它们有自己的主键）绑定 RadGrid 中的数据，然后将此存储过程调用到其他一些 Table 适配器中自己的主键。但是不确定我理解的原因是否正确。

请注意，当我运行 Sql 查询向导中的存储过程工作正常但是当我运行我的页面出现上述错误时。

但我必须使用 3 个表（如上）绑定 RadGrid。我该如何解决这个错误？

Answer 1

替换为以下代码行：

_dtData = SDM.Invoice.GetInvoiceBySPID(_SPID);

与：

_dtData = SDM.Billing.GetBillingBySPID(_SPID);

因为，Invoice TableAdapter/Table 的数据库中已经有主键 table 并且
我正在使用其他数据库 table，它有自己的主键主键，带有 Invoice TableAdapter/Table 因此它给了我错误。问题已解决。
