I am using UltraGrid and UltraCombo of which datasource are same as List<T> and They have checkbox at first column.

If I check/uncheck the checkbox on UltraGrid its state sync with UltraCombo,

but if I check/uncheck the checkbox on UltraCombo, then NotSupportedException occur. (Cell activation not supported)

This is my sample code :

public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}

private void Form1_Load(object sender, EventArgs e)
{
List<Person> lst = new List<Person>();
lst.Add(new Person("N1", "10"));
lst.Add(new Person("N2", "20"));

ultraGrid1.DataSource = lst;
ultraCombo1.DataSource = lst;
}

private void ultraCombo1_InitializeLayout(object sender, Infragistics.Win.UltraWinGrid.InitializeLayoutEventArgs e)
{
foreach (var column in e.Layout.Bands[0].Columns)
{
column.CellActivation = Activation.AllowEdit;
column.CellClickAction = CellClickAction.EditAndSelectText;
}
}
}

public class Person
{
public Boolean Selected { get { return selected; } set { selected = value; } } Boolean selected;
public String Name { get { return name; } } String name;
public String Age { get { return age; } } String age;
public Person() { }

public Person(string name, string age)
{
this.selected = true;
this.name = name;
this.age = age;

}
}
