NetAdvantage For .NET常见技术问题集锦（三）

12.在使用饼图时如何控制Other部分按实际显示

   this.UltraChart1.PieChart.OthersCategoryPercent = 0;

 

13. 如何设置图表中每个序列的颜色

   1. 组合图

NumericSeries numericSeries1 = new NumericSeries();

numericSeries1.PEs.Add( new PaintElement( Color.Green ));//设置颜色

代码中的numericSeries1，您可以根据你程序中具体的series来调用

2.一般的图表

            Override override1 = new Override();

            override1.Column = -2; // 匹配所有列

            override1.Row = 0; // 匹配第一行;

            override1.PE =

            new PaintElement(Color.GreenYellow);

            this.ultraChart1.Override.Add(override1);

 

 14.Grid设置导航

  private void ultraGrid1_KeyDown(object sender, KeyEventArgs e)

        {

            switch (e.KeyCode)

            {

                case Keys.Enter :

                    //MessageBox.Show("sss");

                    this.ultraGrid1.PerformAction(UltraGridAction.BelowCell, false, false);

                    this.ultraGrid1.PerformAction(UltraGridAction.EnterEditMode,false,false);

                    break;

                case Keys.Left:

                    this.ultraGrid1.PerformAction(UltraGridAction.PrevCell, false, false);

                    this.ultraGrid1.PerformAction(UltraGridAction.EnterEditMode, false, false);

                    break;

                case Keys.Right:

                    this.ultraGrid1.PerformAction(UltraGridAction.NextCell, false, false);

                    this.ultraGrid1.PerformAction(UltraGridAction.EnterEditMode, false, false);

                    break;

              

                default:

                   

                    break;
