Daily Tips- Tip #6 - How will you Disable Validation for ASP.NET Server Controls ?

On some pages you will allow users to post even if validations fail. By doing this setting you ask asp.net to by pass validations both at the client and server

For example to bypass validations use this skip button,
<asp:Button id="Button1" runat="server"
Text="Skip" CausesValidation="False">
</asp:Button>

To disable validation at server:

change the validation control's Enabled property to false.

To disable validation at client:

Change the validation control's EnableClientScript property to false.

What are the different modes ASP.NET sessions can be stored?

Asp.net session can be stored in 3 different modes:
1. In-Process
In this mode state is stored in asp.net worker process (aspnet_wp.exe). This is the default mode. The disadvantage is if IIS is restarted state will be lost.
2. State Server
In this mode state is stored in state server (which solves the IIS restart issue as the state server(aspnet_state.exe) can be kept in a separate machine). In this state is serialized and stored.
3. SQL server
Here state is serialized and stored in sql server.
