RE: DataGrid Combobox ColumnStyle with DataSource as ArrayList

Hi again Luke,
I think what I need to do is to use reflection to late bind to the
structures underlying the arraylist, and then use dynamic invocation of their
public properties, as your MyCast function does. Is this way off track?
Thanks.

Dear John,.
Thank you for your reply.
I know you have a performance problem using the ADO.Net and want to use the
ArrayList.
Your ArrayList is consisted of your own structures and you want to cast the
ArrayList by the index to your structure.
If I misunderstand you, please feel free to let me know.
I have written a simple example for you to do this cast,
public class Mydata
{
private int data1;
private String data2;
public Mydata(int n,String s)
{
data1 = n;
data2 = s;
}
public int Data1
{
get
{ return data1;}
set
{ data1 = value;}
}
public String Data2
{
get
{ return data2;}
set
{ data2 = value;}
}
public void MyCast()
{
ArrayList list = new ArrayList();
list.Add(new Mydata(1,"a"));
list.Add(new Mydata(2,"b"));
list.Add(new Mydata(3,"c"));
list.Add(new Mydata(4,"d"));
int i = ((Mydata)list[3]).Data1;
String s = ((Mydata)list[3]).Data2;
}
Hope this information will help you.
