Silverlight 4 DataGrid Print (DataGrid打印解决)

    被此问题困扰了好久，目前依然还是没有完全解决，当前的解决方法可以将DataGrid全部打印出来.

    主要解决的问题是：网上现有的很多打印方法都没有完全解决，一个是不能自动多页打印，然后一个是未显示在浏览器中的部分数据无法打印，此解决方法已解决这些问题。

     

    噢，还有，此方法只写了打印DataGridTextColumn类型的列，其它类型的列未写，若需要用到请自行添加。

   

    生成DataGrid: public static void PrintDataGrid(DataGrid dg, string documentName) { DataGrid datagrid = new DataGrid(); //与原DataGrid生成相同的转换绑定 datagrid.AutoGenerateColumns = false; for (int i = 0; i < dg.Columns.Count; i++) { DataGridTextColumn tmpColumn = new DataGridTextColumn(); DataGridTextColumn column = (DataGridTextColumn)dg.Columns[i]; tmpColumn.Header = column.Header.ToString(); System.Windows.Data.Binding bind ; if (column.Binding != null) { bind = new System.Windows.Data.Binding(); bind.Path = column.Binding.Path; bind.Converter = column.Binding.Converter; } else bind = new System.Windows.Data.Binding(); tmpColumn.Binding = bind; datagrid.Columns.Add(tmpColumn); } datagrid.ItemsSource = dg.ItemsSource; Print(datagrid, documentName); }

     打印DataGrid:(此方法取自于网上，非我所写，只是稍作修改)

public static void Print(UIElement source, string documentName) { var doc = new PrintDocument(); var offsetY = 0d; var totalHeight = 0d; var canvas = new Canvas(); canvas.Children.Add(source); doc.EndPrint += (s, e) => { if (e.Error == null) { MessageBox.Show("打印成功"); } else { MessageBox.Show(e.Error.Message); } }; doc.PrintPage += (s, e) => { e.PageVisual = canvas; canvas.Margin = new Thickness(50); if (totalHeight == 0) { totalHeight = source.DesiredSize.Height; } Canvas.SetTop(source, -offsetY); offsetY += e.PrintableArea.Height; e.HasMorePages = offsetY <= totalHeight; }; doc.Print(documentName); }
