DataGrid and hide column

[vinh tran]

Hi,

I've tried the code in the FAQ How to Hide a Column
http://www.syncfusion.com/FAQ/WinForms/FAQ_c44c.asp#q708q
you gave with GridColumnStyles to the Datagrid's TableStyles.

class MyClass
{
...
ArrayList myList;
...
public void AddObj(Obj o)
{
this.myList.Add(o);
}
}
...
class Obj
{
string Name1;
.....
string NameX;
}

I'd like to display in a datagrid just Name1 or Name2 for example.
I've tried a "normal" table (DataTable) and there is no problem , but for my ArrayList of objects, an ArgumentOutOfRangeException is called : the mapping is not done.

Here is my code :

dataGrid1.DataSource = myClass.myList;
// DataGrid settings
DataGridTableStyle dgts = new DataGridTableStyle();
dgts.MappingName = "myClass.myList";
dataGrid1.TableStyles.Add(dgts);
dgts.GridColumnStyles[2].Width=0;
dgts.DataGrid.Refresh();

Where is the error ?
Thanks
