DevExpress WPF知识点

1、表格右键菜单定位到行

 private void TableView_ContextMenuOpening(object sender, ContextMenuEventArgs e) {
     var tableView = (sender as TableView);
     var hitInfo = tableView.CalcHitInfo(Mouse.GetPosition(tableView));
     if(!hitInfo.InRow || tableView.Grid.IsGroupRowHandle(hitInfo.RowHandle)) {
         e.Handled = true;
     }
 }

 2、CellStyle颜色控制

    <!--  特殊颜色处理 gt(大于) lt(小于)  -->
    <Style
        x:Key="EqColorCellStyle"
        BasedOn="{StaticResource {dxgt:GridRowThemeKey ResourceKey=LightweightCellStyle}}"
        TargetType="{x:Type dxg:LightweightCellEditor}">
        <Style.Triggers>
            <Trigger Property="IsFocusedCell" Value="True">
                <Setter Property="Background" Value="Transparent" />
            </Trigger>
            <Trigger Property="IsKeyboardFocusWithin" Value="True">
                <Setter Property="Background" Value="Transparent" />
            </Trigger>
            <DataTrigger Binding="{DXBinding Expr='(int)Value gt 0'}" Value="True">
                <Setter Property="Foreground" Value="Red" />
            </DataTrigger>
            <DataTrigger Binding="{DXBinding Expr='(int)Value lt 0'}" Value="True">
                <Setter Property="Foreground" Value="Blue" />
            </DataTrigger>
        </Style.Triggers>
    </Style>

比较符号参考：LT、LE、EQ、NE、GE、GT 符号的含义_le lt-CSDN博客

3、新安装VS工具栏中无相应控件：

进入安装目录，执行命令ToolboxCreator.exe /ini:toolboxcreator.ini

C:\Program Files (x86)\DevExpress 21.2\Components\Tools>ToolboxCreator.exe /ini:toolboxcreator.ini
