silverlight柱状图 改变选项事件 和 取消选择

  

      public void T_ConditionSuccess(Object sender, GetConditionCodeRateCompletedEventArgs e)
        {
            if (e.Error == null)
            {
                Successrates.Clear();

                ConditionCodeChart.Axes.Clear();
                ConditionCodeChart.Series.Clear();
                foreach (MDXValue mdv in e.Result)
                {
                    ConditionRatioBind src = new ConditionRatioBind();
                    src.Title = mdv.Title;
                    src.Value = mdv.MValue * 100;
                    Successrates.Add(src);
                }
                ConditionCodeChart.Axes.Clear();
                ConditionCodeChart.Series.Clear();


                ColumnSeries cls = new ColumnSeries();
                cls.ItemsSource = null;
                cls.ItemsSource = Successrates;
                cls.IndependentValueBinding = new Binding("Title");
                cls.DependentValueBinding = new Binding("Value");
                cls.AnimationSequence = AnimationSequence.FirstToLast;
                cls.IsSelectionEnabled = true;
                cls.SelectionChanged += new SelectionChangedEventHandler(cs_SelectionChanged);
                cls.Title = "设备比例";
                ConditionCodeChart.Series.Add(cls);
                //ConditionCodeChart.Title = "特征码设备比例";
                Title += "特征码设备比例";
                ConditionCodeChart.Title = Title;
            }
            else
            {
                Alerts.ShowError(e.Error.ToString());
            }
        }

  

(ConditionCodeChart.Series[0] as ColumnSeries).SelectedItem = null;

这句话代表取消选择。

 

        void cs_SelectionChanged(object sender, SelectionChangedEventArgs e)
        {
            ColumnSeries cs = (ColumnSeries)sender;
            if ((ConditionCodeChart.Series[0] as ColumnSeries).SelectedItem!=null)
            {
                string str = cs.SelectedItem.ToString();
                string name = ((ConditionRatioBind)cs.SelectedItem).Title;
                string param = string.Empty;
                if (name.Contains("语音"))
                {
                    param = "语音";
                }
                if (name.Contains("短信"))
                {
                    param = "短信";
                }
                if (name.Contains("GPRS"))
                {
                    param = "GPRS";
                }
     
                ConditionDetailInfos tpu = new ConditionDetailInfos();
                tpu.ConditionDetailInfosLoad(null, sAreaName, sDateTime, param);
                tpu.Show();
               (ConditionCodeChart.Series[0] as ColumnSeries).SelectedItem = null;
            }
        }
