You can embed check boxes into nodes to allow an end user to check/uncheck individual nodes.
To Embed Check Boxes into Nodes
-
Set the ShowCheckboxes property to true to display check boxes embedded into nodes.
-
Set values of check boxes. Do one of the following:
- Specify the 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>

public class Employee {
public int ID { get; set; }
public int ParentID { get; set; }
public string Name { get; set; }
public string Position { get; set; }
public string Department { get; set; }
public bool OnVacation { get; set; }
}

Checking Nodes in Code
Use the following methods to check/uncheck nodes in code:
When a node's check state is changed, the TreeList View raises the NodeCheckStateChanged event. Use the TreeListNode.IsChecked property to identify whether a node is checked.
