无法在运行时c_wpf的数据表中添加复选框

private void DrawChart() {

ArrayList ar= new ArrayList();
ar.Add("one");
    ar.Add("two");
    ar.Add("three");

        for (int i = 0; i <ar.count ; i++)
        {
                           addRecursiveLedgendAfterInit(ar[i], 50);
        }
    }
private void addRecursiveLedgendAfterInit(string legend,int legendvalue) {

        ICollection<KeyValuePair<String, int>> data = new Dictionary<String, int>();
        data.Add(new KeyValuePair<string, int>(legend, legendvalue));

            ColumnSeries mycolseries = new ColumnSeries
            {
                ItemsSource = data,

                Title = legend,
                IndependentValuePath = "Key",
                DependentValuePath = "Value",

            };

            mainChart.Series.Add(mycolseries);
    }

私有void setappdata() { arraylist aldiscoverednodes=this.discovernetwornodes();

我想通过数据表在数据网格中添加与某些用户相对的复选框。 就像如果一个用户没有在他的计算机上运行ftp协议一样,我让你放置一个未选中的复选框来显示这个用户没有在他的计算机上运行ftp协议。请帮忙
