wpf devexpress

背景 winform切为wpf，使用devexpress插件

参考的网站为：https://docs.devexpress.com/WPF/7875/wpf-controls

1.GridControl行号设置

这里主要有两个问题，一个是行号要从1开始，二是行号这一列的行宽设置（默认行宽到100后，数字就显示不全了）

行宽是IndicatorWidth 属性，行号是RowIndicatorContentTemplate 实现

    <dxg:TableView ShowGroupPanel="False"   Name="gvTable" IndicatorWidth="50"  RowIndicatorContentTemplate="{StaticResource rowIndicatorContentTemplate}"/><DataTemplate x:Key="rowIndicatorContentTemplate"><StackPanel VerticalAlignment="Stretch"HorizontalAlignment="Stretch"><TextBlock Text="{Binding Path=RowHandle.Value,Converter={StaticResource rowIndicatorConverter}}"TextAlignment="Center"Foreground="Black"/></StackPanel></DataTemplate>public class RowIndicatorConverter : IValueConverter{public object Convert(object value, Type targetType, object parameter, CultureInfo culture){try{if (value == null){return 0;}int num = (int) value;num = num + 1;return num;}catch (Exception ex){return 0;}}public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture){return value != null && value.Equals(true) ? parameter : Binding.DoNothing;}}

2.ChartControl 使用

这块wpf和winform的实现还是有点区别的。

legend是图例，通过Orientation和VericalPosition来控制位置。AxisX和AxisY为X和Y轴。

<dxc:ChartControl x:Name="chartControl1" Grid.Column="1" Grid.Row="1"><dxc:ChartControl.Legend><dxc:Legend HorizontalPosition="Center" Orientation="Horizontal" VerticalPosition="TopOutside"  FontSize="10" Background="White" Name="chartLegend"/></dxc:ChartControl.Legend><dxc:XYDiagram2D x:Name="xychart" EnableAxisXNavigation="True" EnableAxisYNavigation="True"><dxc:XYDiagram2D.ContextMenu><ContextMenu><MenuItem Name="miCopy" Header="拷贝到剪贴板" Click="miCopy_Click" /></ContextMenu></dxc:XYDiagram2D.ContextMenu><dxc:XYDiagram2D.AxisX><dxc:AxisX2D><dxc:AxisX2D.Title  ><dxc:AxisTitle/></dxc:AxisX2D.Title></dxc:AxisX2D></dxc:XYDiagram2D.AxisX><dxc:XYDiagram2D.AxisY><dxc:AxisY2D><dxc:AxisY2D.Title  ><dxc:AxisTitle/></dxc:AxisY2D.Title><dxc:AxisY2D.VisualRange><dxc:Range MaxValue="100" MinValue="0"></dxc:Range></dxc:AxisY2D.VisualRange><dxc:AxisY2D.WholeRange><dxc:Range MaxValue="100" MinValue="0"></dxc:Range></dxc:AxisY2D.WholeRange></dxc:AxisY2D></dxc:XYDiagram2D.AxisY></dxc:XYDiagram2D></dxc:ChartControl>

添加数据内容，可以为点（PointSeries2D），曲线（SplineSeries2D），或者饼状图（PieSeries2D）等

  PointSeries2D series1 = new PointSeries2D();series1.DisplayName = featureType;series1.MarkerModel = new CircleMarker2DModel();series1.Brush = Brushes.Red;series1.MarkerSize = 5;

鼠标滚动来放大缩小图片是通过EnableAxisXNavigation和EnableAxisYNavigation，但是默认为true的话初始化后就有滚动条很难看，所以改为当滚轮滚动时，设置这两个值。

    private void xychart_MouseWheel(object sender, MouseWheelEventArgs e){xychart.EnableAxisXNavigation = true;xychart.EnableAxisYNavigation = true;}

图片右键复制

 private void miCopy_Click(object sender, RoutedEventArgs e){MemoryStream stream = new MemoryStream();chartControl1.ExportToImage(stream);System.Windows.Forms.Clipboard.Clear();System.Windows.Forms.Clipboard.SetImage(System.Drawing.Image.FromStream(stream));}

3.GridView.GetDataRow的替换

winform中为 DataRow drFocused = gvHistory.GetDataRow(gvHistory.FocusedRowHandle);

wpf替换为

DataRowView obj = gdXls.GetRow(firstRow - 1) as DataRowView;

DataRow fieldRow = obj.Row;

4.DocumentManager的替换

wpf中用DockLayoutManager 替换同时手动计算每个子窗口的位置（以三行两列为例）

 <dxdo:DockLayoutManager Margin="12" Name="dockManager1"><dxdo:LayoutGroup Orientation="Horizontal"><dxdo:DocumentGroup  x:Name="documentGroup"  DockItemInterval="10" MDIStyle="MDI" Orientation="Vertical"></dxdo:DocumentGroup></dxdo:LayoutGroup></dxdo:DockLayoutManager>private void Window_Loaded(object sender, RoutedEventArgs e){for (int i = 0; i < 3; i++) {for (int j = 0; j < 2; j++) {documentGroup.Items.Add(CreateDocumentPanel(i,j));}}}private DocumentPanel CreateDocumentPanel(int i, int j) {double width = documentGroup.ActualWidth / 2;double height = documentGroup.ActualHeight / 3;DocumentPanel panel = new DocumentPanel(); panel.Name = "panel" + i + j;ucChart control=null;if (j == 0) {if (i == 0) {control = new ucChart(0);}else if (i == 1){control = new ucChart(3);}else if (i == 2){control = new ucChart(5); }}else if (j == 1){if (i == 0){control = new  ucChart(2);}else if (i == 1){control = new ucChart(1);}else if (i == 2){control = new ucChart(4);}}if (control != null){panel.Content = control;}panel.MDISize = new Size(width,height);panel.MDILocation = new Point(j*width,i*height);return panel;}}

5.ImageList图片导出

winfrom中使用ImageList来存放资源，wpf切换时，需要把这些图片导出为png。

     ImageList imageList = new ImageList();System.ComponentModel.ComponentResourceManager resources = new System.ComponentModel.ComponentResourceManager(typeof(MainForm));imageList.ImageStream = ((System.Windows.Forms.ImageListStreamer)(resources.GetObject("img.ImageStream")));int i = 0;foreach (Image img  in imageList.Images){img.Save(i+++".png",ImageFormat.Png);}
