System background
- Platform: WPF
- Product: DXGrid for WPF
The DataContext of the cell element contains the EditGridCellData object.
Use the following binding path to access cell values, columns, and ViewModel properties:
- Value-access the current cell value;
- Column-access the current column;
- RowData.Row.[YourPropertyName]-Access the properties of the object from the ItemsSource collection;
- Data.[FieldName]-Access column values and unbound column values in Server Mode;
- View.DataContext.[YourPropertyName]-Access the ViewModel properties of the grid.
The binding used in this article works as follows:
- Bind ComboBoxEdit.ItemsSource to the Countrys property of the grid's ViewModel:
<dxe:ComboBoxEdit x:Name="PART_Editor" DisplayMember="Name" ItemsSource="{Binding View.DataContext.Countries}" />
Important note: If you want to assign the same ItemsSource collection to all editors in the column, use the EditSettings property instead of CellTemplate to get better performance.
- Bind ComboBoxEdit.ItemsSource to the Cities property stored at the item level:
<dxe:ComboBoxEdit x:Name="PART_Editor" ItemsSource="{Binding RowData.Row.Country.Cities}" />
- Bind Button.Visibility to the unbound column value, and the FieldName of the unbound column is "Visited":
<Button Visibility="{Binding Data.Visited, Converter={dx:BooleanToVisibilityConverter}}">Hide</Button>
- Bind tooltips to display the FieldName of the current column and a cell value:
<Setter Property="ToolTip">
<Setter.Value>
<MultiBinding Converter="{local:CellTooltipConverter}">
<Binding Path="Column.FieldName" />
<Binding Path="Value" />
</MultiBinding>
</Setter.Value>
</Setter>
Important note: You can use the CellToolTipBinding property to specify tool tips for grid cells.
- Bind the background of the cell to the Color property stored at the item level:
<!-- xmlns:dxmvvm="http://schemas.devexpress.com/winfx/2008/xaml/mvvm"; -->
<Style.Triggers>
<Trigger Property="SelectionState" Value="None">
<Setter Property="Background" Value="{Binding RowData.Row.Color, Converter={dxmvvm:ColorToBrushConverter}}" />
</Trigger>
</Style.Triggers>
