DevExpress控件常用代码

1.加载和保存 GridControl 控件布局

 string fileName =Path.Combine(Application.UserAppDataPath, "XtraGrid_SaveLayoutToXML美发员工业绩.xml");        private void EmployeePerformanceTotalForm_Load(object sender, EventArgs e)        {            gridControl1.ForceInitialize();            // Restore the previously saved layout            if (System.IO.File.Exists(fileName))                gridControl1.MainView.RestoreLayoutFromXml(fileName);｝

 private void EmployeePerformanceTotalForm_FormClosing(object sender, FormClosingEventArgs e)        {            // Save the layout to an XML file            gridControl1.MainView.SaveLayoutToXml(fileName);        }

2.DevExpress Gridcontrol Print
   Gridcontrol Print 有两种方法来实现：
一：使用GridControl 自带的ShowPrintPreview方法。
this.gridControl1.ShowPrintPreview();

方法一只是单纯的把gridcontrol1中gridview给打印出来。如果想要设置标题之类的，则需要用方法二来实现。

二：使用PrintingSystem控件。在link Collection中Add PrintableComponentLink。PrintableComponentLink有属性PaperKind(纸张类型)、Landscape(横纵向打印)。
Component的属性为需要打印的控件。打印时要显示标题可以通过PrintableComponentLink的CreateReportHeaderArea来实现

 private void printableComponentLink1_CreateReportHeaderArea(object sender, DevExpress.XtraPrinting.CreateAreaEventArgs e)        {            string reportHeader = "产品基本资料档";            e.Graph.StringFormat = new BrickStringFormat(StringAlignment.Center);            e.Graph.Font = new Font("Tahoma", 14, FontStyle.Bold);            RectangleF rec = new RectangleF(0, 0, e.Graph.ClientPageSize.Width, 50);            e.Graph.DrawString(reportHeader, Color.Black, rec, BorderSide.None);        } //  打印：              this.printableComponentLink1.CreateDocument();            this.printableComponentLink1.ShowPreview();
