Overview

DevExpress WPF Data Editors can be used for in-place editing within the container controls such as GridControl or Bars.

Each editor has a helper class (the BaseEditSettings descendant) responsible for the editor’s functionality. You can use the properties implemented in the *EditSettings class to fully customize the in-place editor. A container control (for example, GridControl) uses information provided by the *EditSettings objects to create editors when required.

GridControl In-Place Editing

When used within the GridControl, the actual editors are only created when end users start to edit a cell and are automatically destroyed when editing is completed.

The following image demonstrates various types of editors nested in the GridControl‘s cells and cards.

The GridControl automatically creates editors for all columns, based on the column value type. To assign a custom editor to a column, use the column’s ColumnBase.EditSettings property.

The following example shows how to assign the combo box and spin editors to grid columns:

View Example: Assign a ComboBox Editor to a Column

XAML

<dxg:GridControl x:Name="grid" ItemsSource="{Binding PersonList}">
    <dxg:GridControl.Columns>
        <dxg:GridColumn FieldName="ProductName" />
        <dxg:GridColumn FieldName="UnitPrice">
            <dxg:GridColumn.EditSettings>
                <dxe:SpinEditSettings MinValue="1" MaxValue="999" />
            </dxg:GridColumn.EditSettings>
        </dxg:GridColumn>
        <dxg:GridColumn FieldName="Type" >
            <dxg:GridColumn.EditSettings>
                <dxe:ComboBoxEditSettings ItemsSource="{Binding TypeList}" DisplayMember="TypeName" ValueMember="Id" />
            </dxg:GridColumn.EditSettings>
        </dxg:GridColumn>
    </dxg:GridControl.Columns>
    <dxg:GridControl.View>
        <dxg:TableView AutoWidth="True" />
    </dxg:GridControl.View>
</dxg:GridControl>

Refer to the Assign Editors to Cells topic for more information.

Bars In-Place Editing

To embed an editor into a bar, use the BarEditItem object. The required *EditSettings object must be assigned to the BarEditItem.EditSettings property.

The following example demonstrates how to use the DateEditSettings and SpinEditSettings objects to embed editors into a bar.

XAML

<Window ...
        xmlns:dxb="http://schemas.devexpress.com/winfx/2008/xaml/bars" 
        xmlns:dxe="http://schemas.devexpress.com/winfx/2008/xaml/editors"
        >
    <Grid>
        <dxb:BarContainerControl ContainerType="Top">
            <dxb:ToolBarControl>
                <dxb:BarEditItem x:Name="editItemDateEdit1" Content="Date" EditValue="01/01/2020" EditWidth="100">
                    <dxb:BarEditItem.EditSettings>
                        <dxe:DateEditSettings />
                    </dxb:BarEditItem.EditSettings>
                </dxb:BarEditItem>
                <dxb:BarEditItem x:Name="editItemSpinEdit1" Content="Value" EditValue="123" EditWidth="100">
                    <dxb:BarEditItem.EditSettings>
                        <dxe:SpinEditSettings />
                    </dxb:BarEditItem.EditSettings>
                </dxb:BarEditItem>
            </dxb:ToolBarControl>
        </dxb:BarContainerControl>
    </Grid>
</Window>

PropertyGridControl In-Place Editing

To embed a specific editor into a property grid cell, assign an editor’s *EditSettings object to the PropertyDefinition.EditSettings property.

The following example demonstrates how to assign editors to property grid rows based on the property path and type.

XAML

<Window.DataContext>
    <local:ViewModel/>
</Window.DataContext>
...
<dxprg:PropertyGridControl SelectedObject="{Binding Data}" ShowProperties="All">
    <dxprg:PropertyDefinition Path="ID" IsReadOnly="True"/>
    <dxprg:PropertyDefinition Type="sys:DateTime">
        <dxprg:PropertyDefinition.EditSettings>
            <dxe:DateEditSettings DisplayFormat="MMM-dd-yyyy"/>
        </dxprg:PropertyDefinition.EditSettings>
    </dxprg:PropertyDefinition>
    <dxprg:PropertyDefinition Type="sys:String">
        <dxprg:PropertyDefinition.EditSettings>
            <dxe:TextEditSettings MaxLength="15"/>
        </dxprg:PropertyDefinition.EditSettings>
    </dxprg:PropertyDefinition>
</dxprg:PropertyGridControl>

C#

public class ViewModel {
    public SimpleModel Data { get; set; }
    public ViewModel() {
        Data = new SimpleModel()
        {
            ID = 0,
            FirstName = "Anna",
            LastName = "Trujilo",
            Birthday = new DateTime(1987, 09, 14)
        };
    }
}

public class SimpleModel {
    public int ID { get; set; }
    public string FirstName { get; set; }
    public string LastName { get; set; }
    public DateTime Birthday { get; set; }
}
