Two-way XamDataGrid field binding

Question

I have the following code inside XamDataGrid:

 <igDp:Field Name="IsBlackChecked"  Label="Black Image" />

The problem is that this is not a two-way binding. When I click the checkbox in the user interface, the value is not set.

I tried the following solution:

 <igWPF:Field Name="IsBlackChecked" Label="Black Image" Width="Auto"  >
    <igWPF:Field.Settings>
      <igWPF:FieldSettings AllowEdit="True">
        <igWPF:FieldSettings.EditorStyle>
          <Style TargetType="{x:Type igWPF:XamCheckEditor}" 
            BasedOn="{StaticResource {x:Type igWPF:XamCheckEditor}}" >                                                <Setter Property="IsChecked"                                                        Value="{Binding DataItem.IsBlackChecked, Mode=TwoWay}"/>
           </Style>
         </igWPF:FieldSettings.EditorStyle>
        <igWPF:FieldSettings.CellValuePresenterStyle>
       <Style TargetType="{x:Type igWPF:CellValuePresenter}">
         <Setter Property="Template">
          <Setter.Value>
           <ControlTemplate TargetType="{x:Type igWPF:CellValuePresenter}">
            <CheckBox IsChecked="{Binding DataItem.IsBlackChecked, Mode=TwoWay}" HorizontalAlignment="Center" VerticalAlignment="Center"/>
           </ControlTemplate>
          </Setter.Value>
         </Setter>
        </Style>
       </igWPF:FieldSettings.CellValuePresenterStyle>
      </igWPF:FieldSettings>
     </igWPF:Field.Settings>
   </igWPF:Field>

This gives me a two-way snap, but it changes the style of the cell and the boundary lines go away,

How can I specify two-way binding in this field in the first parameters / restore border lines in the second?

<igDp:Field Name="IsBlackChecked"  Label="Black Image" />

By default, these are two ways binding(you can check any data type). The real problems in your scenario could be

• checkbox, CellvaluePresenter moues click event. , , checkbox, checkbox. ( .)
• INotifyProertyChanged model class. , ( ) record, property ().

:

editorstyle, cellvaluepresenterstyle. editorstyle ( cellvaluepresentrer . , border cell, , , . )

editorstyle template/bindings, . , .
