Hi!

I have a webpage with a DataGrid and a codebehind file containing a method
called OrderStatusText

The line in question in the asp page
<ItemTemplate>

   <%# OrderStatusText((byte)Eval("OSTATUS")) %>
</ItemTemplate>

I got the message: Specifyed cast not valid when i ran the page

The method looks like

public string OrderStatusText(byte status)
{
   do stuff
   return stuff
}

Any idea why it's not possible?

I got the cast code from the msdn2 pages.

Regards
Martin

You can write:
<%# OrderStatusText(Convert.ToByte(Eval("OSTATUS"))) %>
