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.

Exception Details: System.IndexOutOfRangeException: CDI_C

thanks

you are not returning the field "CDI_C" in your stored procedure "sp_GetlData"

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.

{
    CDI_C = Convert.ToInt32(dr["CDI_C"]);
