Hi all,
How can i refresh crystal reports?

Iam using VS.NET2003 and using vs.net i created a aspx webpage and on the
page i
placed a drop dwon list and a button...

Dropdown list will display the student no and when the user clicsk on the
button it will display the report which is created using CR.net..

But my problem is when the user changes the data in drop donw list
iam not getting the expected result...

How can i solve this problem?

Regards
Jackfadd

hi Jack,
do you have AutoPostBack = true on the DropDownList?
do you have a SelectedIndexChanged event handler on the DropDownList?
what is your code in the SelectedIndexChanged event handler?
how are you presenting the crystal report to the user?

i'm happy to help but you'll have to give us a few hooks to understand what
is going wrong

hi Jack,
for one thing, you have some code that makes no sense:

If (Not Me.IsPostBack) Then
MyReport.SetDatabaseLogon(USERID, PW)
Else
...

if you have a Button click event handler, then it will always be a postback.
so you should remove that code.

also, i think you have to call .DataBind() on the report viewer.
hope this helps
tim

Hello Tim,
Thanks for the help...

You gave me a wonderful tip and with that I could make it work fine...

Now iam struck with double byte character display and printing of the report
direclty from CR..

Do you have any idea how to rectify the above said problems?

Regards
Jack

hi Jack,
i also don't know much about character encoding problems with crystal
reports.
i'd say you'd have better luck starting a new thread.
good luck
