if you have such control in your aspx page :
<uc1:PrintProposalFees ID="PrintProposalFees1" runat="server" />
pass the values from code behind like this :
this.PrintProposalFees1.ProposalID= "3 or your value";
remeber to call the controll ID not the control!
AND in your control put this property:
namespace UHSRFP.Features.UI
{
public partial class PrintProposalFees : UserControl
{
private int myproposalID = -1;
public int ProposalID
{
get { return myproposalID ; }
set { myproposalID = value; }
}
thats all
