我正在使用InfoPath 2007,並使用C#進行編碼。我想要做的就是填充字段合同號,有多個領域,是合同期結束日期(dtTo,這必須是在格式YYYY/MM,這是選擇一個日期選擇器),項目編號(ddlPortfolio,一個下拉列表中選擇),序列號(這是從數據庫中檢索時,SQL Server 2005)和基金類型(bFundType,選擇一個選項按鈕)。使用多個字段值填充字段
現在我所做的是我已經使用了一種方法來嘗試填充字段合同編號。該方法被稱爲生成ContractNo,其中有云:
public string GenerateContractNo()
{
string sSequence = "";
//IPCode.popSeq(this.CreateNavigator(), this.NamespaceManager, DataSources, this.MainDataSource);
//string seqNo = this.CreateNavigator().SelectSingleNode("/my:myRoot/my:SectionHeading/my:sSequence", NamespaceManager).InnerXml;
string sPortfolio = this.CreateNavigator().SelectSingleNode("/my:myRoot/my:SectionHeading/my:ddlPortfolio", NamespaceManager).InnerXml;
string sYear = this.CreateNavigator().SelectSingleNode("/my:myRoot/my:SectionHeading/my:dtTo", NamespaceManager).InnerXml;
string sMonth = this.CreateNavigator().SelectSingleNode("/my:myRoot/my:SectionHeading/my:dtTo", NamespaceManager).InnerXml;
//string sSeq = this.CreateNavigator().SelectSingleNode("/my:myRoot/my:SectionHeading/my:sSequence", NamespaceManager).InnerXml;
string sFundType = this.CreateNavigator().SelectSingleNode("/my:myRoot/my:SectionHeading/my:bFundType", NamespaceManager).InnerXml;
//Convert.ToInt16(sSeq);
// return sYear + "/" + sMonth + "/" + sPortfolio + "/" + sSeq + "/" + sFundType;
sSequence = sYear + "/" + sMonth + "/" + sPortfolio + "/" + sFundType;
this.CreateNavigator().SelectSingleNode("/my:myRoot/my:SectionHeading/my:sSequence", this.NamespaceManager).SetValue(sSequence);
//CourseDetails = dtSDate.ToLongDateString() + " - " + dtEDate.ToLongDateString() + " | " + sLocation + " | " + SDCategory;
//CourseDetailsFields = sTitle + "|" + dtSDate.ToLongDateString() + "|" + dtEDate.ToLongDateString() + "|" + sLocation + "|" + SDCategory;
//lstDetails.Add(CourseDetailsFields, CourseDetailsFields);
return null;
}
我試圖同時使用一個名爲PopSeq類,填充序列號字段,從數據庫中,它調用調用的存儲過程的序列號,uspGetSeqNo。以下是類,以及存儲過程:
static public int popSeq(XPathNavigator xnMyForm, XmlNamespaceManager ns, DataSourceCollection ds, DataSource mds)
{
try
{
SqlConnection conn = new SqlConnection(IPCode.defaultConnectionString);
SqlCommand command = new SqlCommand("[uspGetSeqNo]", conn);
conn.Open();
command.CommandType = CommandType.StoredProcedure;
//XPathNavigator domNav = mds.CreateNavigator();
//string sVendor = domNav.SelectSingleNode("/my:myRoot/my:SectionHeading/my:ddlVendor", this.NamespaceManager).ToString();
//command.Parameters.AddWithValue("@iSequence", s);
SqlDataReader myReader = command.ExecuteReader();
while (myReader.Read())
{
string iSequence = Convert.ToString(myReader.GetOrdinal("iSequence"));
//return Convert.ToInt16(sSeq);
}
}
catch (Exception ex)
{
throw ex;
}
return 0;
}
存儲過程:
USE [TAU_PANEL]
GO
/****** Object: StoredProcedure [dbo].[uspGetSeqNo] Script Date: 04/06/2011 08:52:14 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER PROCEDURE [dbo].[uspGetSeqNo]
AS
SELECT MAX(iSequence) + 1 AS seq
FROM dbo.ResAllocations
所以我的問題是,在按鈕保存,它不填充合同編號字段。對不起,我是C#的新手。
感謝導遊,還有......將這樣做 – Martin 2011-04-06 08:59:25
