Hello

BindingList<MyObj> blMyObj;
public sealed class MyObj
{
    #region "Declaration"
    private int _Id;
    private int _ParentId;
    private string _Name = "";
    private string _Description;
    #endregion

    #region "Property"
    public int Id
    {
        get { return _Id; }
        set { _Id = value; }
    }

    public int ParentId
    {
        get { return _ParentId; }
        set { _ParentId = value; }
    }

    public string Name
    {
        get { return _Name; }
        set { _Name = value; }
    }

    public string Description
    {
        get { return _Description; }
    }
    #endregion

    public MyObj(int idObj,int ParentIdObj, string nameObj,string DescriptionObj)
    {
        _Id = idObj;
        if (ParentIdObj!=0) _ParentId = ParentIdObj;
        _Name = nameObj;
        _Description = DescriptionObj;
    }
}

private void frm_Load(object sender, EventArgs e)
{
    radGridView1.DataSource=bindingSource1;
    this.bindingSource1.PositionChanged += new System.EventHandler(this.bindingSource1_PositionChanged);
    blMyObj = new BindingList<MyObj>();
    blMyObj.Add(new MyObj(1,0, "Allen",""));
    blMyObj.Add(new MyObj(2,0, "Carolina", ""));
    blMyObj.Add(new MyObj(3,1, "Whitney", ""));
    blMyObj.Add(new MyObj(4,3, "Sarah", ""));
    blMyObj.Add(new MyObj(5,0, "Dun", ""));
    blMyObj.Add(new MyObj(6,5, "Tu-Lin", ""));
    blMyObj.Add(new MyObj(7, 6,"Alexandra", ""));
    blMyObj.Add(new MyObj(8,0, "Tammy", ""));

    radGridView1.Relations.AddSelfReference(radGridView1.MasterTemplate, "Id", "ParentId");
    this.bindingSource1.DataSource = blMyObj;
 }

 private void bindingSource1_PositionChanged(object sender, EventArgs e)
{

}

The Event bindingSource1_PositionChanged does not work correct.

Hello Sari,

You already use a bindingList that supports collection change notifications, why do you need a bindings source to?

Just set the datasource of the grid to that bindingList and delete will work

radGridView1.DataSource = blMyObj;

With the other issue, with the position change, it's strange, but honestly i cannot see a scenario where you might need it, because you always have the current row / the data bound item to that row...

Hello Emanuel,
Using bindingList is just an example. This problem occurs with any data source.

Also is not working properly displaying alternative rows.
EnableAlternatingRowColor=true;
