Embed Check Boxes into Nodes

1. Set the TreeListView.ShowCheckboxes property to true to display check boxes embedded into nodes.

2. Set values of check boxes. Do one of the following:

   • Specify the TreeListView.CheckBoxFieldName property to bind check boxes to a Boolean field in the grid’s data source.
   • Check nodes in code.

The code sample below shows how to display check boxes and bind them to the OnVacation field:

Xaml

<dxg:GridControl Name="gridControl">
    <dxg:GridControl.Columns>
        <dxg:GridColumn FieldName="Name"/>
        <dxg:GridColumn FieldName="Department"/>
        <dxg:GridColumn FieldName="Position"/>
    </dxg:GridControl.Columns>
    <dxg:GridControl.View>
        <dxg:TreeListView KeyFieldName="ID" ParentFieldName="ParentID" AutoExpandAllNodes="True"
            CheckBoxFieldName="OnVacation" ShowCheckboxes="True" />
    </dxg:GridControl.View>
</dxg:GridControl>
