Databinding in combo box
- by muralekarthick
Hi
I have two forms, and a class, queries return in Stored procedure.
Stored Procedure:
ALTER PROCEDURE [dbo].[Payment_Join]
@reference nvarchar(20)
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;
-- Insert statements for procedure here
SELECT p.iPaymentID,p.nvReference,pt.nvPaymentType,p.iAmount,m.nvMethod,u.nvUsers,p.tUpdateTime
FROM Payment p, tblPaymentType pt, tblPaymentMethod m, tblUsers u
WHERE p.nvReference = @reference
and p.iPaymentTypeID = pt.iPaymentTypeID
and p.iMethodID = m.iMethodID
and p.iUsersID = u.iUsersID
END

i have already binded the combo box items through designer,
When i run the application i just get the reference populated in form 2 and combo box just populated not the particular value which is fetched. New to c# so help me to get familiar
