Thanks for you the last reply..
Am Adewale Olalekan from Lagos,Nigeria, working with alpsltd.com as programmer and web administrator
We are into logistics(supply chain), so am trying to develop a web application for keeping track of every
transactions and customer tracking system. so that the customer can track the goods and papers we are delivering on their
behalf online. :).. we have tried to developed this using coldfusion, but the development time was getting
longer and my boss is not taking things easy for me, so we then try .net approach, am from the family
of vb 6, so i quickly adopted vb.net (many people use C#, after this project, i ll migrate to c#. good huh? :) )

when i came across submodal (dtml without .net), didnt see it very useful, so with your enhancement to .net, i found it very very useful. Thanks bro.

*Back to my post for the today.*

1. I used hidden field to pass variables, thinking of using session variables, i used session variables in coldfusion development, i think am comfortable.

2. Because am learning and developing, the project time is dragging again, so i will need your help here

*Basic Information Gathering Scenario for the project*
I use a single web form page for the information gathering. i.e on that page
-I do record navigation, add new record, modify record, delete record and save.
(I have separate server side buttons for all these functionalities)
so i have 5 buttons - add, modify, add, delete,save and view list (pop up :- submodal this is for navigation)
Add - enable the form,will clear all the fields and disable other buttons and itself, except save
Modify - enable the form execept id, and disable other buttons and itself, except save
Delete - delete record
save - update the dataset, and enable other buttons except disable d form and itself
view list- throw a pop up (submodal control)- use for navigation

what i notice is that every button click will cause a postback. with this i cant use validation controls, they validate,

how I can

(1) make the all buttons except save button not to cause postback because at every postbacks validate control will validate I want postback for save button only.

or

(2) make the buttons run at client side and be able to call a group subroutines or methods on server

Thanks. This will make my work easy. I can send the development so far if you like to look through.

Thanks

answer to this one is easy, EnableValidation = false
but this gets tricky when you come across something like the following senario:
you have button A
you have button B
you have validator 1 on txt1
and validator 2 on txt2

If you click on button A you need just validator1 to be checked not 2
when you click on button B you need only validator 2 to be checked or enabled.
In such a senario I found that client side intervention is necessary. We can remove validator2 and set EnableValidation on Button B to false, then we use onclick of button B to do the work of checking what we need to check and return false when we don't want to allow a postback. Returning false from any funtion that is called upon the onclick event of the button means we are telling the form not to submit...
We can get more crafty by using a combination of validators and javascript tp enable and disable them, show and hide them....
