CRXPF0008 - In-place editing is not available when NavigationStyle is set to Row or None

• Feb 14, 2023

Severity: Warning

The analyzer detects that you set the ColumnBase.AllowEditing or DataViewBase.AllowEditing property to true, and the DataViewBase.NavigationStyle property is not set to Cell. In this case, users cannot use in-place data editors to edit cell values. If the DataViewBase.NavigationStyle property is set to Row, you can still allow users to edit data in the Edit Form.

Examples

Invalid Code

XAML

<dxg:GridControl ...>
    <dxg:GridControl.View>
        <!-- A DevExpress.Xpf.Grid.DataViewBase descendant: -->
        <dxg:TableView NavigationStyle="Row" .../>
        <!-- OR -->
        <dxg:TableView NavigationStyle="None" .../>
    </dxg:GridControl.View>
    <dxg:GridColumn FieldName="Name" AllowEditing="True"/>
    <!-- ... -->
</dxg:GridControl>

Valid Code

XAML

<dxg:GridControl ...>
    <dxg:GridControl.View>
        <!-- A DevExpress.Xpf.Grid.DataViewBase descendant: -->
        <dxg:TableView NavigationStyle="Cell" .../>
        <!-- OR -->
        <dxg:TableView .../>
    </dxg:GridControl.View>
    <dxg:GridColumn FieldName="Name" AllowEditing="True"/>
    <!-- ... -->
</dxg:GridControl>

<!-- OR -->

<dxg:GridControl ...>
    <dxg:GridControl.View>
        <!-- A DevExpress.Xpf.Grid.DataViewBase descendant: -->
        <dxg:TableView NavigationStyle="Row" EditFormShowMode="Inline" .../>
    </dxg:GridControl.View>
    <dxg:GridColumn FieldName="Name" AllowEditing="True"/>
    <!-- ... -->
</dxg:GridControl>

How to Fix

• Set the DataViewBase.NavigationStyle property to Cell to allow users to edit data in the grid’s in-place data editors.

• If the DataViewBase.NavigationStyle property is set to Row, users can only edit data in the Edit Form. Specify the EditFormShowMode property to display an edit form when a user double-clicks a row.
