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);
            }
