While some developers assume that the classical ASP.NET validators support check boxes and radio buttons, this isn’t the case! There is a logical explanation for this; there is nothing much to check, the checkbox can only be checked or unchecked so what do you want to validate?
In some cases you might want to display an error if a check box or a radio button is unchecked, e.g. terms and conditions check box, if so, then this is the right validator for you. Read on if you are interested in the bits and pieces of how the control works or skip to the “Using The Validator” section if you are just interested in using it.Tagged under:11 comments|

Session expiration in ASP.NET is a nasty problem. Imagine yourself filling a long form, hitting submit then boom you get the login page! That happened to me before and probably happened to you.
This problem doesn’t have an out-of-box solution in ASP.NET and there are different appraoches to solve it.
- Increasing the session time out. Probably you are aware of the cons of this problem which are mainly consuming more server resources.
- Having an image or an iframe that refreshes regularly and requests the server. This approach is a per page approach and you can select the pages to implement it on.
Personally, I’ve been using the second approach for a long time and didn’t have any problem with it. However, I made it more reusable, not to mention “cleaner”, by making it a web control.
If you are just interested in using the control then you can skip to the last section “Using the Control.”Tagged under:12 comments|
