钟表维修管理系统技术解析(四) 销售单录入中的录入数据

录入销售单这个模块，可以录入销售单，如果一个客户同时修多个表，有个再录一条按钮为同一个客户录入多条销售单，最后结账如(图1)所示。

(图1)

从界面上可以看到我们这里用到的控件有

控件名称	说明
日期控件（DateTimePicker）	控件可以在工具箱直接拖动至窗体，拖至窗体后右击属性可以修改控件的样式和各种属性，还可以编辑事件。
下拉框（ComboBox）
文本（TextBox）
按钮（Button）
数据表格（DataGridView）

数据库表与关系如(图2)所示：

一、录入数据

1、绑定下拉框

第一步：存储过程

IF (@TYPE = 'frmXiaoShouKaiDan_Insert_Load_SelectTrueBaoXiuQi')BEGIN SELECT     BaoXiuQiID, RTRIM(BaoXiuQiMingCheng) AS BaoXiuQiMingCheng,YouXiaoFou--查询的列FROM         sys_BaoXiuQi--从哪个表查询WHERE     YouXiaoFou=1--查询条件END  IF (@TYPE = 'frmXiaoShouKaiDan_Insert_Load_SelectXiaoShouLeiXing')BEGINSELECT       ShuXingMingXiID AS ShuXingMingXiID,LTRIM(RTRIM(ShuXingMingXiMingCheng))AS ShuXingMingXiMingCheng--查询的列FROM      sys_ShuXingMingXi--从哪个表查询WHERE      ShuXingJiHeID=18 AND YouXiaoFou=1--查询条件ENDIF (@TYPE = 'frmXiaoShouKaiDan_Insert_Load_SelectZhongBiaoKuanShi')BEGINSELECT      ShuXingMingXiID AS ShuXingMingXiID,LTRIM(RTRIM(ShuXingMingXiMingCheng))AS ShuXingMingXiMingCheng--查询的列FROM      sys_ShuXingMingXi--从哪个表查询WHERE      ShuXingJiHeID=28 AND YouXiaoFou=1--查询条件END

第二步：逻辑层(BLL)代码

DALPublic.DALMethod myDALMethod = new DALPublic.DALMethod();//实例化数据层(DAL)public DataTable frmXiaoShouKaiDan_Insert_Load_SelectTrueBaoXiuQi()//方法名称{SqlParameter[] mySqlParameters ={new SqlParameter("@TYPE",SqlDbType.Char)//声明变量数组};mySqlParameters[0].Value = "frmXiaoShouKaiDan_Insert_Load_SelectTrueBaoXiuQi";//给变量数组的第一个赋值return myDALMethod.QueryDataTable("frmXiaoShouKaiDan_Insert", mySqlParameters);//第一个参数是数据库名称，第二个参数是数组}public DataTable frmXiaoShouKaiDan_Insert_Load_SelectXiaoShouLeiXing(){SqlParameter[] mySqlParameters ={new SqlParameter("@TYPE",SqlDbType.Char)};mySqlParameters[0].Value = "frmXiaoShouKaiDan_Insert_Load_SelectXiaoShouLeiXing";return myDALMethod.QueryDataTable("frmXiaoShouKaiDan_Insert", mySqlParameters);}public DataTable frmXiaoShouKaiDan_Insert_Load_SelectZhongBiaoKuanShi(){SqlParameter[] mySqlParameters ={new SqlParameter("@TYPE",SqlDbType.Char)};mySqlParameters[0].Value = "frmXiaoShouKaiDan_Insert_Load_SelectZhongBiaoKuanShi";return myDALMethod.QueryDataTable("frmXiaoShouKaiDan_Insert", mySqlParameters);}

第三步：界面层(UIL)代码，窗体的Load事件

private void frmXiaoShouKaiDan_Insert_Load(object sender, EventArgs e){保修期.DataSource = myfrmXiaoShouKaiDan_Insert.frmXiaoShouKaiDan_Insert_Load_SelectTrueBaoXiuQi();//绑定数据源保修期.DisplayMember = "BaoXiuQiMingCheng";//绑定显示文本保修期.ValueMember = "BaoXiuQiID";//绑定IDcboKuanShi.DataSource = myfrmXiaoShouKaiDan_Insert.frmXiaoShouKaiDan_Insert_Load_SelectZhongBiaoKuanShi();//绑定数据源cboKuanShi.DisplayMember = "ShuXingMingXiMingCheng";//绑定显示文本cboKuanShi.ValueMember = "ShuXingMingXiID";//绑定IDcboXiaoShouLeiXing.DataSource = myfrmXiaoShouKaiDan_Insert.frmXiaoShouKaiDan_Insert_Load_SelectXiaoShouLeiXing();cboXiaoShouLeiXing.DisplayMember = "ShuXingMingXiMingCheng";cboXiaoShouLeiXing.ValueMember = "ShuXingMingXiID";dgvChanPinMingXi.AutoGenerateColumns = false;//设置DGV不能自动创建列dgvChanPinMingXi.AllowUserToAddRows = false;//设置DGV不能手动添加行txtXiaoShouDanBianHao.Text = "自动生成";//给销售单编号文本框赋值}

2、选择客户，界面如(图3)、(图4)所示

(图3)

(图4)

第一步：添加客户的单击事件

private void btnTianJiaKeHu_Click(object sender, EventArgs e){if (intGeShu > 0)//如果是按了[再录一条]按钮，则不能更换客户{MessageBox.Show("当前客户已绑定，如果不同客户请结账后再录入！", "提示！", MessageBoxButtons.OK, MessageBoxIcon.Error);return;}GongGongChuangTi.frmKeHu myfrmKeHu = new GongGongChuangTi.frmKeHu();//实例化选择客户窗体myfrmKeHu.ShowDialog();//弹出窗体if (GongGongChuangTi.frmKeHu.pubKeHuID != 0)//判断选择客户窗体是否按了关闭或者返回，如果是就不更改客户信息{intKeHuID = GongGongChuangTi.frmKeHu.pubKeHuID;//赋值语句，GongGongChuangTi.frmKeHu这个前缀是选择客户窗体的静态变量txtKeHuXingMing.Text = GongGongChuangTi.frmKeHu.pubKeHuXingMing;txtLianXiDianHua.Text = GongGongChuangTi.frmKeHu.pubLianXiDianHua;txtLianXiDiZhi.Text = GongGongChuangTi.frmKeHu.pubLianXiDiZhi;}}

第二步：选择客户的Load事件

public static int pubKeHuID = 0;
public static string pubKeHuXingMing = "";
public static string pubLianXiDianHua = "";
public static string pubLianXiDiZhi = "";
public static string pubKeHuLeiXing = "";private void frmKeHu_Load(object sender, EventArgs e){dgvKeHe.AllowUserToAddRows = false;//禁止手动添加行dgvKeHe.AutoGenerateColumns = false;//禁止自动添加列dgvKeHe.ReadOnly = true;//禁止编辑DGVcboYeDaXiao.Text = "20";//每页数量默认为20行pubKeHuID = 0;//一打开窗体就把客户信息清空，方便判断是否确定选择pubKeHuXingMing = "";pubLianXiDianHua = "";pubLianXiDiZhi = "";pubKeHuLeiXing = "";btnChaXun_Click(null, null);//调用查询方法}

第三步：客户的模糊查询、分页功能

(1)数据库的存储过程

CREATE PROCEDURE ShuJuBiaoGe_FenYeChaXun@tblName varchar(4000), -- 表名@strGetFields varchar(4000) = '*', -- 需要返回的列@fldName varchar(255)='''', -- 排序的字段名@PageSize int = 10, -- 页尺寸@PageIndex int = 1, -- 页码@doCount bit output, -- 返回记录总数, 非0 值则返回@OrderType bit = 0, -- 设置排序类型, 非0 值则降序@strWhere varchar(1500) = '''' -- 查询条件(注意: 不要加where)ASdeclare @strSQL varchar(5000) -- 主语句declare @strTmp varchar(110) -- 临时变量declare @temp varchar(100)--截取后的临时变量declare @strOrder varchar(400) -- 排序类型if @doCount != 0beginif @strWhere !=''''set @strSQL = 'select count(*) as Total from ' + @tblName + ' where '+@strWhereelseset @strSQL = 'select count(*) as Total from ' + @tblName + ''end

private void dgvPinPai_CellMouseDoubleClick(object sender, DataGridViewCellMouseEventArgs e){try{pubPinPaiID = Convert.ToInt32(dgvPinPai.CurrentRow.Cells["品牌ID"].Value);pubPinPaiMingCheng = dgvPinPai.CurrentRow.Cells["品牌名称"].Value.ToString().Trim();this.Dispose();this.Close();}catch{ }}

确定按钮的单击事件

private void btnQueDing_Click(object sender, EventArgs e){if (dgvPinPai.Rows.Count > 0){pubPinPaiID = Convert.ToInt32(dgvPinPai.CurrentRow.Cells["品牌ID"].Value);pubPinPaiMingCheng = dgvPinPai.CurrentRow.Cells["品牌名称"].Value.ToString().Trim();this.Dispose();this.Close();}else{MessageBox.Show("当前没有可操作的数据，请查询！");}}

4、选择产品，界面如(图7)、(图8)所示
