mapcontrol如何自动加载代码中添加的坐标值和线段属性画图

在VS2010arcgis engine中mapcontrol中操作,实现点击触发一个点击事件，或者运行就直接加载，自动加载代码中添加的坐标值和线段属性画图。
private void button1_Click(object sender, EventArgs e)
        {
            //首先要实现容器接口
            IGraphicsContainer pGraphicsContainer = axMapControl1.ActiveView as IGraphicsContainer;
            pGraphicsContainer.DeleteAllElements();//清空容器里面所有的元素

            //设置点的坐标
            IPoint pPoint = new PointClass();
            pPoint.PutCoords(310, 310);

            //IMarkerElement用来获得symbol属性
            IMarkerElement pMarkerElement = new MarkerElementClass();

            //用ISimpleMarkerSymbol来设置点的属性
            ISimpleMarkerSymbol pSymbol = new SimpleMarkerSymbolClass();
            IRgbColor pRGBcolor = new RgbColorClass();
            pRGBcolor.Red = 255;
            pRGBcolor.Green = 0;
            pRGBcolor.Blue = 0;
            pSymbol.Color = pRGBcolor;//红色
            pMarkerElement.Symbol = pSymbol;

            //IElement用来获得Geometry属性
            IElement pElement = pMarkerElement as IElement;

            //把IPoint转换为为IGeoMetry也能实现
            //IGeometry pGeometry = pPoint as IGeometry;
            //pElement.Geometry = pGeometry;
            pElement.Geometry = pPoint;

            //在容器里添加元素
            pGraphicsContainer.AddElement(pElement, 0);
            pElement.Activate(axMapControl1.ActiveView.ScreenDisplay);
            axMapControl1.ActiveView.PartialRefresh(esriViewDrawPhase.esriViewGraphics, pElement, null);
        }

//首先要实现容器接口
            IGraphicsContainer pGraphicsContainer = axMapControl1.ActiveView as IGraphicsContainer;

            //设置点的坐标

            for (int i = 0; i <= 100; i = i + 10)
            {
                IPoint pPoint = new PointClass();
                pPoint.PutCoords(300 + i, 300 + i);
