Binding an arraylist to a datagrid

[David H.]

I'm trying to bind an arraylist to a datagrid web control

The arraylist contains "mystates" objects with properties named "state" and "abbreviation.

I can set the grid's datasource to be the arraylist, but I am having trouble referencing the properties of each arraylist item by their name. For example, the grid doesn't like

<asp:boundcolumn datafield="state" /

Is there an easy way around this

Thanks

use a datatable whereas to arraylist for this. I dont think the datagrids
allows this with arraylists, however i could easily be wrong.

Hi,

how are you exactly trying to do that. In my test I had a Datagrid

<aspataGrid id="DataGrid1" runat="server" AutoGenerateColumns="False" >
<Columns>
<asp:BoundColumn DataField="State" />
</Columns>
</aspataGrid>

I had a class MyState:

Public Class MyState
Private _abbreviation As String
Private _State As String
Public Sub New(ByVal abbreviation As String, ByVal state As String)
_abbreviation = abbreviation
_State = state
End Sub
Public ReadOnly Property Abbreviation() As String
Get
Return _abbreviation
End Get
End Property
Public ReadOnly Property State() As String
Get
Return _State
End Get
End Property
End Class

which was used with the grid:

Dim arrList As New ArrayList
arrList.Add(New MyState("A1", "1"))
arrList.Add(New MyState("A2", "2"))
arrList.Add(New MyState("A3", "3"))
DataGrid1.DataSource = arrList
DataGrid1.DataBind()

And it worked just fine.

Are you perhaps using C#? Have you make sure that it's not anything related
just to case-sensitivity, if you are?
