DataViewBase.CellTemplate Property

Gets or sets the template that defines the presentation of data cells. This is a dependency property.

Namespace: DevExpress.Xpf.Grid

Assembly: DevExpress.Xpf.Grid.v19.1.Core.dll

Declaration

C#

public DataTemplate CellTemplate { get; set; }

VB.NET

Public Property CellTemplate As DataTemplate

Property Value

Type	Description
DataTemplate	A DataTemplate object that defines the presentation of data cells.

Remarks

The binding source for the CellTemplate template is specified by the GridCellData class. Each column provides the ColumnBase.CellTemplate property that allows you to specify a custom template used to render its cells.

The code sample belows shows how to use a custom ComboBoxEdit within grid cells:

Xaml

<dxg:GridControl AutoGenerateColumns="AddNew" EnableSmartColumnsGeneration="True" ItemsSource="{Binding Items}">
    <dxg:GridColumn FieldName="Country"/>
    <dxg:GridColumn FieldName="City">
        <dxg:GridColumn.CellTemplate>
            <DataTemplate>
                <dxe:ComboBoxEdit x:Name="PART_Editor" ItemsSource="{Binding RowData.Row.Cities}"/>
            </DataTemplate>
        </dxg:GridColumn.CellTemplate>
    </dxg:GridColumn>
    <dxg:GridControl.View>
        <dxg:TableView/>
    </dxg:GridControl.View>
</dxg:GridControl>

C#

public ObservableCollection<CountryCities> Items {
    get {
        if(this._Items == null) {
            this._Items = new ObservableCollection<CountryCities>();

            CountryCities usa = new CountryCities() {
                Country = "USA",
                Cities = new List<string> { "Washington, D.C.", "New York", "Los Angeles", "Las Vegas" },
                City = "Los Angeles"
            };
            this._Items.Add(usa);

            CountryCities germany = new CountryCities() {
                Country = "Germany",
                Cities = new List<string> { "Berlin", "Munich", "Frankfurt" },
                City = "Munich"
            };
            this._Items.Add(germany);

            CountryCities russia = new CountryCities() {
                Country = "Russia",
                Cities = new List<string> { "Moscow", "Saint-Petersburg" },
                City = "Moscow"
            };
            this._Items.Add(russia);
        }
        return this._Items;
    }
}

Tip

• For the DevExpress Data Editors (the BaseEdit class’s descendants), you can set the editor’s Name property to PART_Editor. In this case, the GridControl automatically adjusts its appearance and synchronizes the editor with the source field specified by the ColumnBase.FieldName or ColumnBase.Binding properties.
• You can use any binding with an editor named PART_Editor. In this case, the GridControl‘s logic of getting/setting the editor’s value is disabled.
• You can specify the following validation binding properties: ValidatesOnDataErrors, ValidatesOnExceptions, NotifyOnValidationError, and NotifyOnSourceUpdated.

Tip

A template that defines the presentation of data cells is specified by the CellTemplate property. If you have more than one template that can be used to render cells, you can implement custom logic to choose the required template. To do this, derive from the DataTemplateSelector class, implement the SelectTemplate method that returns a template which meets the required condition, and assign it to the DataViewBase.CellTemplateSelector property.

If both the CellTemplate and DataViewBase.CellTemplateSelector are specified, a cell is rendered using the template returned by the template selector. If the template selector returns null, the template specified by the CellTemplate property is used.

Note

When using the CellTemplate, an editor specified with the ColumnBase.EditSettings property is ignored (but its formatting settings persist).

Note

Editors specified in the CellTemplate do not affect data processing (sorting, grouping, filtering, summary calculation) and export.

Use the PrintCellStyle property to customize cell appearance when printing and exporting the GridControl‘s data.

The GridControl.CustomColumnDisplayText allows you to display custom text within any cell. The provided text is used when the grid is printed.
