I've been working in a project for some time now, and I'm having some hard times trying to figure out how to copy data from one gridview to another.

What I want to do is this: My web aplication will list all content the user have in a gridview (dynamically binded to a database), and it will have a button "+" that when clicked, it will copy that 2 columns of that row to another gridview.

I've tried some times and it works copy the very first row (no matter what row is that), but then it do not work anymore.

Here is the asp.net code:

<div id="Musicas">
    <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="Name" DataSourceID="ObjectDataSource1" OnRowCommand="GridView1_RowCommand">
        <Columns>
            <asp:BoundField DataField="Name" HeaderText="Name" SortExpression="Name" />
            <asp:BoundField DataField="Gender" HeaderText="Gender" SortExpression="Gender" />
            <asp:BoundField DataField="Album" HeaderText="Album" SortExpression="Album" />
            <asp:BoundField DataField="ReleaseYear" HeaderText="ReleaseYear" SortExpression="ReleaseYear" />
            <asp:BoundField DataField="Composer" HeaderText="Composer" SortExpression="Composer" />
            <asp:BoundField DataField="Artist" HeaderText="Artist" SortExpression="Artist" />
            <asp:ButtonField ButtonType="Button" CommandName="Select" HeaderText="AddPlayList" ShowHeader="True" Text="+" />
        </Columns>
    </asp:GridView>
    <asp:ObjectDataSource ID="ObjectDataSource1" runat="server" OnSelecting="ObjectDataSource1_Selecting" SelectMethod="GetMusic" TypeName="BLL.GetUserInformation">
        <SelectParameters>
            <asp:Parameter Name="id" Type="String" />
        </SelectParameters>
    </asp:ObjectDataSource>

    <asp:GridView ID="GridView2" runat="server" AutoGenerateColumns="False">
        <Columns>
        <asp:BoundField DataField="Name" HeaderText="Name" />
    </Columns>
    </asp:GridView>
</div>

And here is the code-behind:

private List<Row> CopiedData
    {
        get
        {
            if (this.ViewState["CopiedData"] == null)
            {
                this.ViewState["CopiedData"] = new List<Row>();
            }

            return this.ViewState["CopiedData"] as List<Row>;
        }
    }

    protected void Page_Load(object sender, EventArgs e)
    {

    }


    protected void ObjectDataSource1_Selecting(object sender, ObjectDataSourceSelectingEventArgs e)
    {
        e.InputParameters[0] = User.Identity.Name;
    }

    protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
    {
        if (e.CommandName.Equals("Select"))
        {
            GridViewRow gvr = GridView1.Rows[Convert.ToInt32(e.CommandArgument)];
            int id = Convert.ToInt32(GridView1.DataKeys[gvr.RowIndex]["Name"]);
            string character = gvr.Cells[0].Text;
            Row row = new Row { Id = id, Name = character };

            if (!this.CopiedData.Exists(r => r.Id == id))
            {
                this.CopiedData.Add(row);

                GridView2.DataSource = this.CopiedData;
                GridView2.DataBind();
            }
        }
    }


    [Serializable()]
    private class Row
    {
        public int Id { get; set; }
        public string Name { get; set; }
    }

The issue I'm having is in this line of code:

int id = Convert.ToInt32(GridView1.DataKeys[gvr.RowIndex]["Name"]);
for it always retuns 0 to id, making the if (!this.CopiedData.Exists(r => r.Id == id)) always return false, so it do not update the code after the first line was selected.

Can anyone help me with this?

Thanks in advance and sorry about my poor english, its not my main language.
