Hello,

I'm getting this error when I try to read the data from the db

I'm trying to read:
CDI_N varchar 50
CDI_D varchar 50
CDI_C float  8
CDI_NA bit 1
the problem is on the CDI_C

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

I added Debug="true" and the error points to: Line 256:            if (dr["CDI_C"] != null)

In the database the CDI_N, CDI_C, CDI_NA are value =  NULL

 CDI_C

here is the getdata procedure
ALTER   PROCEDURE dbo.sp_GetData(@Login as varchar(25), @DataYr as int, @DataQtr as tinyint)
AS
    BEGIN
        declare @oshpid int
        
       set @oshpid  = (select OSHPDID
	   from _Login 
	   where UserID = @Login)
	   
	   select CDI_N, CDI_D, CDI_NA
	   from _Data
	   where OSHPDID = @oshpid
	   and DataYr = @DataYr
	   and DataQtr = @DataQtr

select CDI_N, CDI_D, CDI_NA CDI_C
         from _Data
         where OSHPDID = @oshpid
         and DataYr = @DataYr
         and DataQtr = @DataQtr

There is your problem.

Note the "0" between the ? and the  : can be any default value you would like for CDI_C.

try:
if (!dr.IsDBNull(dr.GetOrdinal("CDI_C")))
{
    CDI_C = Convert.ToInt32(dr["CDI_C"]);
