Hi Dreyar,

According to your description, I find that the text value in your 'lblRoomName' was always bound to empty. You could bound the data into text filed like this:

<asp:Label ID="lblRoomPrice" runat="server" Text='<%#Eval("RoomPrice")%>'></asp:Label>

I made a complete demo, you could refer to it:

.Aspx:

<form id="form1" runat="server">
    <div>
        <asp:Repeater ID="rptrProductDetails" runat="server">
            <ItemTemplate>
                <asp:Label ID="lblRoomPrice" runat="server" Text='<%#Eval("RoomPrice")%>'></asp:Label>
                <asp:Label ID="lblRoomName" runat="server" Text='<%#Eval("RoomName")%>'></asp:Label>
                <h4 class="pull-right"><%#Eval("RoomPrice")%></h4>
                <h4><%#Eval("RoomName")%></h4>
                <asp:Button ID="btnAddToCart" runat="server" Text="AddtoCart" OnClick="btnAddToCart_Click" />
                <br /><br />
            </ItemTemplate>
        </asp:Repeater>       
        <asp:GridView ID="GridView1" runat="server"></asp:GridView>
    </div>
    </form>

.Aspx.cs:

Protected Sub Page_Load(sender As Object, e As EventArgs)
If Not IsPostBack Then
Dim dt As New DataTable()
dt.Columns.Add(New DataColumn("RoomName"))
dt.Columns.Add(New DataColumn("RoomPrice", GetType(System.Int32)))
dt.Rows.Add("name1", 1)
dt.Rows.Add("name2", 2)
dt.Rows.Add("name3", 3)
rptrProductDetails.DataSource = dt
rptrProductDetails.DataBind()
End If
End Sub
Protected Sub btnAddToCart_Click(sender As Object, e As EventArgs)
Dim roomName = DirectCast(DirectCast(sender, Button).Parent.FindControl("lblRoomName"), Label)
Dim roomPrice = DirectCast(DirectCast(sender, Button).Parent.FindControl("lblRoomPrice"), Label)
Dim ds As DataSet = Nothing
If Session("sCart") Is Nothing Then
ds = New DataSet()
Dim dt As New DataTable()
dt.Columns.Add(New DataColumn("RoomName"))
dt.Columns.Add(New DataColumn("RoomPrice", GetType(System.Int32)))
ds.Tables.Add(dt)
Session("sCart") = ds
Else
ds = DirectCast(Session("sCart"), DataSet)
End If
Dim row As DataRow = ds.Tables(0).NewRow()
row("RoomName") = roomName.Text
row("RoomPrice") = roomPrice.Text
'row["RoomName"] = ((Label)rptrProductDetails.Controls[0].FindControl("lblRoomName")).Text;
'row["RoomPrice"] = ((Label)rptrProductDetails.Controls[0].FindControl("lblRoomPrice")).Text;
ds.Tables(0).Rows.Add(row)
GridView1.DataSource = ds.Tables(0)
GridView1.DataBind()
End Sub

Output screenshot as below:

Best regards,

Cathy
