Thank for your reply!
I created an hashtable, which i use to fill my dropdownlist.
On my form i've got a dropdownlist, 1 button and a textfield.
When i click on the button, all values in my form (textbox and dropdownlist)
are lost!
Keep in mind that everything worked fine on my local machine and viewstate
is enabled.
Your help is much appreciated
Regards,
Ron

news:%2****************@tk2msftngp13.phx.gbl...I developed a webesite using c#. I have a dropdownlist wich is filled with
database values. When i click on a button on the same page all values are
lost in the dropdownlist.
The most common answer is to populate the ddl in "if !is postback" which
i did. When i debug it seems that before the postback all values are
lost.
When i tried to do the same on my local machine (localhost) everything
works fine.
Can someone please help
regards
Ron
