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dataribbonPage1 protected 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 Properties protected 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")); } } }
3.CellPropertiesViewerModule

} } public Protection Protection { get { return range.Protection; } } public Style Style { get { return range.Style; } } public string NumberFormat { get { return Cell.NumberFormat; } set { Cell.NumberFormat = value; } } } }
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); } }
7.取消所有的合并单元格
foreach (var item in spreadsheetControl1.ActiveWorksheet.Cells.GetMergedRanges()) { item.UnMerge(); }
