本文通过一个具体的事例,为大家阐述如何绑定DevExpress的 PivotGridControl 到数据库。
事例数据库如下:
代码如下:
C#
using DevExpress.LookAndFeel; using DevExpress.XtraPivotGrid; using System.Data.OleDb; // Create a connection object. OleDbConnection connection = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\\DB\\NWIND.MDB"); // Create a data adapter. OleDbDataAdapter adapter = new OleDbDataAdapter("SELECT * FROM SalesPerson", connection); // Create and fill a dataset. DataSet sourceDataSet = new DataSet(); adapter.Fill(sourceDataSet, "SalesPerson"); // Assign the data source to the XtraPivotGrid control. pivotGridControl1.DataSource = sourceDataSet.Tables["SalesPerson"]; // Create a row PivotGridControl field bound to the Country datasource field. PivotGridField fieldCountry = new PivotGridField("Country", PivotArea.RowArea); // Create a row PivotGridControl field bound to the Sales Person datasource field. PivotGridField fieldCustomer = new PivotGridField("Sales Person", PivotArea.RowArea); fieldCustomer.Caption = "Customer"; // Create a column PivotGridControl field bound to the OrderDate datasource field. PivotGridField fieldYear = new PivotGridField("OrderDate", PivotArea.ColumnArea); fieldYear.Caption = "Year"; // Group field values by years. fieldYear.GroupInterval = PivotGroupInterval.DateYear; // Create a column PivotGridControl field bound to the CategoryName datasource field. PivotGridField fieldCategoryName = new PivotGridField("CategoryName", PivotArea.ColumnArea); fieldCategoryName.Caption = "Product Category"; // Create a filter PivotGridControl field bound to the ProductName datasource field. PivotGridField fieldProductName = new PivotGridField("ProductName", PivotArea.FilterArea); fieldProductName.Caption = "Product Name"; // Create a data PivotGridControl field bound to the 'Extended Price' datasource field. PivotGridField fieldExtendedPrice = new PivotGridField("Extended Price", PivotArea.DataArea); fieldExtendedPrice.CellFormat.FormatType = DevExpress.Utils.FormatType.Numeric; // Specify the formatting setting to format summary values as integer currency amount. fieldExtendedPrice.CellFormat.FormatString = "c0"; // Add the fields to the control's field collection. pivotGridControl1.Fields.AddRange(new PivotGridField[] {fieldCountry, fieldCustomer, fieldCategoryName, fieldProductName, fieldYear, fieldExtendedPrice}); // Arrange the row fields within the Row Header Area. fieldCountry.AreaIndex = 0; fieldCustomer.AreaIndex = 1; // Arrange the column fields within the Column Header Area. fieldCategoryName.AreaIndex = 0; fieldYear.AreaIndex = 1; // Customize the control's look-and-feel via the Default LookAndFeel object. UserLookAndFeel.Default.UseWindowsXPTheme = false; UserLookAndFeel.Default.Style = LookAndFeelStyle.Skin; UserLookAndFeel.Default.SkinName = "Money Twins";
