When transfer is defined above with reference to the event parameter is a simple string, if the parameters to be passed more complex, it can be encapsulated using the object parameters.

A delegate in the form of defined events

public delegate void RefreshChartInOneDelegete(XYModel xYModel);
public static event RefreshChartInOneDelegete OnRefreshChartInOne;

 

Wherein the package is their XYModel parameters Model, according to needs its own specific packaging.

 

public class XYModel
    {
        // store the X-axis property 
        Private XAxisModel xAxisModel;
         // store Y axes attributes 
        Private List <YAxisModel> yAxisModelList;

        
        public XAxisModel XAxisModel
        {
            get { return xAxisModel; }
            set { xAxisModel = value; }
        }

        public List<YAxisModel> YAxisModelList
        {
            get { return yAxisModelList; }
            set { yAxisModelList = value; }
        }
    }

 

Define the trigger

 xYModel.YAxisModelList = yAxisModelList;
            if (OnRefreshChartInOne != null)
            {
                OnRefreshChartInOne(xYModel);
                
            }

 

Then subscribe to events in the form B

FrmChartOptionInOneCurCom.OnRefreshChartInOne += new FrmChartOptionInOneCurCom.RefreshChartInOneDelegete(ChartCompareHelper_OnRefreshChart);

 

Write the specific implementation in the form B

 private void ChartCompareHelper_OnRefreshChart(XYModel xYModel)
        {
            xYModelStore = xYModel;
            ChartCompareHelper.RefreshPaneComInOne(this.zedGraphControl1,xYModel.YAxisModelList);
        }
