Hi,
I have a dropdownlist from which i select the type of diagram i want to display.
I note that when i select an item from the dropdownlist i fill the hashtable used by the diagram from the database accordingly.
the problem is that i have an exception:
La valeur ne peut pas être null.
Nom du paramètre : Invalid Graph!
I have to find a solution for tomorrow,please help!
PS:I'm using the sample file
Thanks.
