silverlight visifire控件图表制作——silverlight 后台方法ControlChart.xaml.cs

一、构造方法ControlChart

1、前台页面控件赋值

 //时间下拉框赋值，下拉框赋选定值
                for (int ii = DateTime.Today.Year; ii >= 1980; ii--)
                {
                    string item = string.Format("{0}年", ii.ToString());
                    this.dateYear.Items.Add(item);
                    if (item == sClickReportDate)
                    {
                        this.dateYear.SelectedValue = sClickReportDate;//下拉框赋选定值
                    }
                }

2、页面地名下拉框绑定数据，下拉框赋选定值
 string str = "大庆,吉林,辽河,华北,大港,冀东,浙江,新疆";

 string[] address = str.Split(‘,‘);
            for (int i = 0; i < address.Length; i++)
            {
                this.addressNameList.Items.Add(address[i]);
                if (address[i] == ChartTitle)
                {
                    this.addressNameList.SelectedValue = ChartTitle;//下拉框赋选定值
                }
            }

3、调整页面布局
                this.dateStart.Visibility = Visibility.Collapsed;//不显示控件
                this.dateYear.Visibility = Visibility.Visible;//显示控件
                this.addressName.Margin = new Thickness(167, 16, 0, 0);//位置
                this.addressNameList.Margin = new Thickness(212, 12, 0, 0);
                this.btnDown.Margin = new Thickness(322, 12, 0, 0);
                this.dtName.Margin = new Thickness(412, 16, 0, 0);
                this.showData.Margin = new Thickness(470, 18, 0, 0);

4、查询方法（调用wcf获取画图信息）

Query();

 private void Query()
{
DBServiceClient svc = new DBServiceClient(); //调用wcf

//委托
svc.GetSingleChartDataCompleted += new EventHandler<GetSingleChartDataCompletedEventArgs>(svc_GetSingleChartDataCompleted);
//调用wcf的GetSingleChartData 方法

//（详细方法请参考博文：silverlight visifire控件图表制作——wcf）

svc.GetSingleChartDataAsync(strReportDate, strEndReportDate, sTNameClick, sXName);        

}

5、打印

（详细请参考博文：silverlight visifire控件图表制作——silverlight 后台方法打印 http://www.cnblogs.com/xuxin-1989/p/3819686.html）

6、委托方法

 private void svc_GetSingleChartDataCompleted(object sender, GetSingleChartDataCompletedEventArgs e)
        {

//获得wcf 返回值
            ObservableCollection<ListItem> lBaseOilBar = e.Result;

//画图
            CreateChart(this.gridVisifire, lBaseOilBar);

        }

7、画图方法（详细请参考博文：silverlight visifire控件图表制作——silverlight 后台方法画图方法）

8、页面事件
