Hi,

[ngokulkumar]

[thaond]

hi !
I think that the error is : for(int i=0; i<= qci.Count; i++)
{
..............
}
for example : int[] a={1, 2, 3, 4, ,5} has 5 elements, i can't access 6th element.
for(int i=0; i< a.Length; i++)
{
............... (i=0, i=1, i=2, i=3, i=4) has total elements = 5.
}
if I access the 6th element, means : i=5
-> Exception : ArgumentOutOfRa ngeException
bye!

Thank you all for your response.

qci is of type varchar in MS sql database.

Thank You,

The problem comes from i <= qci.Count

.Count is the total number in there, not the highest index.
For example if the .Count was = 3, then the index values are [0],[1],[2], you on the other hand are trying to reference [3], which doesn't exist, so you get the index out of range.
Change it to:
i<qci.Count

Thanks Plater,

I figure that out.

Can any one point out for a good tutorial to use crystal report on .net website using c#?

Thanks,
