    //temp.AmIPartOfCollection - want to get false
    //temp.MyCollection - want to get null

    SomeCollection sc = new SomeCollection();
    sc.Add(temp);

    //temp.AmIPartOfCollection - want to get true
    //temp.MyCollection - want to get reference to "sc" object
}

OraConn.ConnectionString = Dts.Variables["OraConn"].Value.ToString();

<pre>
listView1.ColumnClick += new ColumnClickEventHandler(this.MyLstVw_Vsble)

private void MyLstVw_Vsble(object Sender, EventArgs e)
{
       listView1.Visible = false; 
}


But my clarification is, why not assigning the controls visible property, directly like the below.


listView1.ColumnClick += listView1.Visible = true;
