Asp.net, How can I hide controls....?

How can i hide a .Net control (lets say listbox) without postback the page??


using scripts!!!!Asp.net, How can I hide controls....?
The problem you face is that ASP.NET will rename your controls, which makes it difficult to locate them by ID in JavaScript.





You need to use Atlas, the JavaScript add-on for ASP.NET 2, or wait for ASP.NET 3 to come out, which will incorporate Atlas.

ASP.NET cannot find controls which are made in another subroutine?

Hi (again) ,


My page is now looking like this





Sub page_load


if not page.ispostback then


getData()


End Sub





Sub getData()


Read db records


Create dynamic controls


End Sub





Sub saveData()


get dynamic controls info


save results to db


call getData()


End Sub





Now the problem is that in the saveData() i cannot seem to access my dynamic controls anymore using Dim questionQuery As TextBox = questionHolder.FindControl(';questionQuer鈥?The error this throws at me is %26lt;%26lt;Object reference not set to an instance of an object. %26gt;%26gt;.


Does anyone have a clue what this might cause?





Thanks in advance for your time


Greetings


MarkASP.NET cannot find controls which are made in another subroutine?
If you are declaring and creating the controls inside the getDate sub then the controls will only exists while your code is inside that sub. As soon as you leave it, the scope of the application changes and anything done inside the sub is lost.





If you want to have something last throughout execution you will need to declare it at a higher level so that any sub under that level can use it.





You may want to try to create a control class to hold your dynamic controls. That way, you can access the class from inside any sub.ASP.NET cannot find controls which are made in another subroutine?

You know in advance programming sometimes we have to validate values.


The best example is Email ID and Password.


This is a kind of validation.





so we have different kind of validation such as :


1.Required field validator


2.RegularExpression


3.Range Validator


4.Custom Valdiator





each of them does an special task of validating.


for example one of them is RangeValditaor : you give a range of number .


for example 3-6.


if the number entered by the user was in this range it would return true and else false.
