globle variable not accesed in functions

jmorge · Apr 28, 2012

hi, I have decleared a globle variable as a datatable. I have modified it in a function. (I am not decleared it again in function. as I am using globle variable). But when I again calling it in another function I got error the datatable is null. I have tried to create the datatable in pageload but it is not working in that way also. How to solve this problem. TIA Regards Rajkumar My aspx files goes like this <html> <head> <script language="VB" runat="server"> Dim objTable as DataTable Sub Page_Load(Sender As Object, e As EventArgs) function1() end sub sub function1() 'code to get values objTable = myDataset.Tables("values") 'code to display objTable. It is displaying here correctly End sub sub function2(sender As Object, e As ImageClickEventArgs) 'code to work with objTable. It is giving error as objTable is null End sub </script> </head> <body> <asp:ImageButton id="id1" onclick="function2" runat="server" ImageUrl="image.gif" ></asp:ImageButton> </body> </html> these functions are being called at different times, right?yes, The function1 called when the pageis loaded. the function2 called when button is clicked. rajkumarSub Page_Load(Sender As Object, e As EventArgs) function1() end sub sub function1() 'code to get values objTable = myDataset.Tables("values") 'code to display objTable. It is displaying here correctly End sub sub function2(sender As Object, e As ImageClickEventArgs) 'code to work with objTable. It is giving error as objTable is null End sub when it posts back, it DOESN't call page_load() therefore it doesn't call function1 http://www.readthe****ingmanual.co.uk/thanks Atrax, I am calling the function in page_init(), and it is working fine now. Thanks again rajkumarglad i could help. also worth pointing out I don't use ASP.NET - just a pure concept answer.... ;-)
