This works fine:
<% Session["Session_player"]=1; %>
but this:
<% Session["Session_player"]=%> <%# DataBinder.Eval(Container.DataItem,
"playerID") %> <%; %>

do not work.

The playerID contains the value 1, so the values in both examples are the
same.
What do you suggest - where should i look ??
 
Hi Jesper:

Keep the entire statement inside the data binding delimeters:

<%# Session["Session_player"] =
DataBinder.Eval(Container.DataItem, "playerID") %>

HTH,
 
Hi Scott !

Great...thanks.....now is works......nearly as planned.......

Now, I got to figure out why Session["Session_player"] contains the last
value in the database rather than the current value.

It is assigned in:
<ItemTemplate>
<a href="player_details.aspx?spillerID=<%#
DataBinder.Eval(Container.DataItem, "PlayerID") %>"
target="_parent"> <%# DataBinder.Eval(Container.DataItem,
"playerFirstName") %>
<%#
DataBinder.Eval(Container.DataItem, "playerLastName") %> </a>
<%# Session["Session_player"] =
DataBinder.Eval(Container.DataItem, "playerID") %>
</ItemTemplate>
The <%# Session["Session_player"] = DataBinder.Eval(Container.DataItem,
"playerID") %> display correctly in the Datagrid.

I´am trying to get the player_details.aspx file to receive the current
player.
The spillerID will not be acceptet and now the Session["Session_player"] is
changed to contain the last value in the database insted.

Cmd = new OleDbCommand("SELECT * FROM tblPlayers WHERE PlayerID = " +
Session["Session_player"] + " ", Conn);

Hi Jesper -

If the data binding is inside of a Repeater or DataGrid, then it will
execute for each row in the data source. The last assignment will be
from the last row in the data source.

What you might want to do is add some logic so the assignment only
happens on a row that is selected. Look at the ItemDataBound event,
perhaps you could pull it out there. Alternatively, you could add some
additional logic to the data binding expression. See:
