Hi,

I'm using a datatable as the datasource for a xamDatagrid (in a mvvm scenario, so I dont have direct access to the view from the viewmodel side)

I have found several issues when using databinding with the grid:

1) The captions of the datatable aren't being used as the labels (I have already posted about this issue elsewhere and it is being investigated - its not the main concern of this post, but I thought the issues may just be related). It does work if you use the following syntax: dgContacts.DataSource = dt.AsEnumerable(); but since I'm using mvvm I cant interact with the grid directly with the viewmodel http://news.infragistics.com/forums/t/25645.aspx

2) Changing the caption of the column in the datatable does not update the field label in the grid. This happens even when using a "normal" wpf app and using the dt.AsEnumerable syntax.

Here is a bit of sample code (not using mvvm in the sample)

private void LoadData()
{
dt = new DataTable();
                dt.Columns.Add(new DataColumn { ColumnName = "ContactID", Caption = "Contact ID" });
                dt.Columns.Add(new DataColumn { ColumnName = "ContactName", Caption = "Contact Name" });
                dt.Columns.Add(new DataColumn { ColumnName = "ContactSurname", Caption = "Contact Surname" });

                DataRow dr = dt.NewRow();
                dr[0] = "1";
                dr[1] = "Jacques";
                dr[2] = "Doubell";
                dt.Rows.Add(dr);

                dgContacts.DataSource = dt.AsEnumerable();
}

private void button1_Click(object sender, RoutedEventArgs e)
        {
            dt.Columns[0].Caption = "New Caption";          
        }

Any help would be appreciated, thanks!
