Default Casting DataGridItem.DataItem to Object

Hi

I'm binding an array of objects to a datagrid. I then want to select a few of these items before proceeding to the next page.

My problem is that I can't cast the DataGridItem.DataItem from the datagrind into a custom type.

Here's the code:

// this is the datagrid
protected System.Web.UI.WebControls.DataGrid CollNoteResults;

// here's the array of my objects - CollNoteStatements
// inherits from ArrayList...
CollNoteStatements cnss = new CollNoteStatements();

// here's the databind
this.CollNoteResults.DataSource = cnss;
CollNoteResults.DataBind();

// here's the DataGridItem - it's in a loop with index i
DataGridItem dgi = (DataGridItem) CollNoteResults.Items[i];

// here's me trying to cast the DataItem out as a type
// this is where it starts to go wrong
CollNoteStatement cns = dgi.DataItem as CollNoteStatement;

Although there's no build error, the variable cns is simply not set (or set to null).

Please help someone?

Thanks
Tom

all i know about a datagrid is it can bounded to DataTable Else I Don't think

So Create Datasource as table and fill it and bind it to datagid ...That's all

Thanks Ahmed, although all I really want to do is retrieve an object from an object-bound datagrid. So your proposal of binding it into a datatable is not helpful in this instance. But thanks for replying.
