hello all,

I have a simple question. on my .aspx page I have bunch of
textbox, and dropdowns. One of the dropdown2 has postback
= true. When the user selects an item, the brower will
post back to the server. My problem is I only wants the
browser will post back to the server if (textbox1,
textbox2, and dropdown1) are not null values. I have a
javascript that checks for the null value for textbox1,
textbox2, and dropdown1. how can i do in client-side,
postback occurs only if certain fields are not blank.
Please let me know if u have any suggestion or any
examples that help..



Thanks
manan
 
use validation controls and set the CausesValidation to true for the
control that has AutoPostBack.
Validate in the validation control what you want to be not null.
