ASP simple gridview with paging

Question

In my aspx I have:

<asp:GridView ID="GridView1" runat="server" AllowPaging="True" 
    AllowSorting="True" AutoGenerateColumns="True">
</asp:GridView>

I have a very simple class:

class ItemTable
{
    public ItemTable(string mc, string dt)
    {
        this.Machinecode = mc;
        this.Datetime = dt;
    }
    string Machinecode { get; set; }
    string Datetime { get; set; }
}

And in my code I have:

List<ItemTable> infos = new List<ItemTable>(); 
//Some code for add item in infos...
GridView1.DataSource = infos;
GridView1.DataBind();

But i have this error:

The data source for GridView with id 'GridView1' did not have any properties or attributes from which to generate columns. Ensure that your data source has content.

How do I fix this ?

Answer 1

Change your properties to public like this

class ItemTable
{
    public ItemTable(string mc, string dt)
    {
        this.Machinecode = mc;
        this.Datetime = dt;
    }
    public string Machinecode { get; set; }
    public string Datetime { get; set; }
}

When no access-specifier is mentioned, private is taken as access-specifier.
