C# WinfForm 控件之dev电子表格 SpreadSheet

网上找了一些资料可是不得入门只能再回过头来看demos

看了一点例子大多继承自SpreadsheetRibbonTutorialControlBase 这个类，它又继承自SpreadSheetTutorialControlBase 再往前就不说了

SpreadSheetTutorialControlBase 这个类呢只是定义了两个属性可能就是运行语言格式的没有注释

SpreadsheetRibbonTutorialControlBase 这个呢又定义了一个属性 selectPage 看样是选中的按钮页的意思,类型是 RibbonPage 又绑定了两个方法一个是单元格值改变另一个呢是是最后编辑，我想是这样的看名字（spreadsheetControl1_CellValueChangedOverride、spreadsheetControl1_CellEndEditOverride）这个类就有所有的控件了，这是他的样子。有个doShow()（大约是显示的意思）方法这个应继承自最基类的dll里先不管什么意思

再看他的子类们

1.AutoFilterModule 打开一个文档看注释

namespace DevExpress.XtraSpreadsheet.Demos {public partial class AutoFilterModule : SpreadsheetRibbonTutorialControlBase {public AutoFilterModule() {InitializeComponent();// 这个是en-US 。。。英语的 （汉化的话 在程序入口加 en-Hans 这去百度用法）spreadsheetControl1.Options.Culture = DefaultCulture;//这个打开路径下的 auto...xlsx表格 getRelativePath是取程序路径 可以看到spreadsheetControl1.LoadDocument就是把文档加到spreadSheetControl中   spreadsheetControl1.LoadDocument(DemoUtils.GetRelativePath("AutoFilter_template.xlsx"));}#region Properties 重载了 选中dataribbonPage1protected internal override RibbonPage SelectedRibbonPage { get { return dataRibbonPage1; } }#endregion}
}

2。 BreakevenAnalysisModule 定义一个workBook 接收 ssc.document ssc是spreadSheetControl下同并加载excel表格这个有点错误 ssc.docment 是取ssc上的sheet的意思

namespace DevExpress.XtraSpreadsheet.Demos {public partial class BreakevenAnalysisModule : SpreadsheetRibbonTutorialControlBase {public BreakevenAnalysisModule() {InitializeComponent();InitializeWorkbook();}#region Propertiesprotected internal override RibbonPage SelectedRibbonPage { get { return insertRibbonPage1; } }#endregion//新建一个空文档 并加入excel表格  IWorkbook=spreadsheetControl1.Document;void InitializeWorkbook() {IWorkbook workbook = spreadsheetControl1.Document;workbook.LoadDocument(DemoUtils.GetRelativePath("BreakevenAnalysis.xlsx"));}}
}

4.ChartApiMode 这个显示c#与VB的demo 后能不管他了看他前台的demo 这里只看一个

 private void button1_Click(object sender, EventArgs e){IWorkbook workbook = ssc.Document;Worksheet worksheet = workbook.Worksheets["sheet2"];worksheet.Cells["B2"].Value = "Phone";worksheet.Cells["c2"].Value = "pecent";worksheet.Cells["B4"].Value="adriod";worksheet.Cells["c4"].Value = 70;worksheet.Cells["b3"].Value = "iso";worksheet.Cells["c3"].Value = 30;workbook.Worksheets.ActiveWorksheet = worksheet;// 建一个本地图. 取值区间如果有无效数据则忽略DevExpress.Spreadsheet.Charts.Chart chart = worksheet.Charts.Add(ChartType.PieExploded, worksheet["B3:C4"]);//图表位置chart.TopLeftCell = worksheet.Cells["E2"];chart.BottomRightCell = worksheet.Cells["K15"];// 颜色类型.chart.Style = ChartStyle.ColorArea;// 隐藏右侧的说明chart.Legend.Visible = false;// 第一个切片的角度 .chart.Views[0].FirstSliceAngle = 0;// 各个切片是否显示名称 百分比 及显示方式为换行.DataLabelOptions dataLabels = chart.Views[0].DataLabels;dataLabels.ShowCategoryName = true;dataLabels.ShowPercent = true;dataLabels.Separator = "\n";}

5.ConditionalFormatting 这个主要是改变背景色等显示代码实现在TopTradingPartners这个静态类里只看一个例子

  public static void ApplyTopImportsConditionalFormatting(Worksheet sheet) {ConditionalFormattingCollection conditionalFormattings = sheet.ConditionalFormattings;// 建一个 imports 列 5个格改变颜色.RankConditionalFormatting cfRule2 = conditionalFormattings.AddRankConditionalFormatting(sheet["Table[Imports]"], ConditionalFormattingRankCondition.TopByRank, 5);// Specify formatting options to be applied to cells if the condition is true.// Set the background color to light-red.cfRule2.Formatting.Fill.BackgroundColor = Color.FromArgb(0xFC, 0xB3, 0xB3);}

6.删除空列（空行同只不过是遍历行操作）

 for (int i = spreadsheetControl1.ActiveWorksheet.Columns.LastUsedIndex; i >= 0; i--){bool b = false;for (int j = spreadsheetControl1.ActiveWorksheet.Rows.LastUsedIndex; j >= 0; j--){if (spreadsheetControl1.ActiveWorksheet.Rows[j][i].Value.ToString() != ""){b = true;break;}}if (!b){spreadsheetControl1.ActiveWorksheet.Columns.Remove(i);}}

View Code

7.取消所有的合并单元格

 foreach (var item in spreadsheetControl1.ActiveWorksheet.Cells.GetMergedRanges()){item.UnMerge();}
