Implement Validation in our Project

Hello friends,

How can i implement the validation in our project, means if validation == true then the next page will open else shows an error message.
please reply.

Thanks.

Hi,

You can implement page validations but,

Page.Validate is not the same as Page.IsValid (obviously)

I've never found a reason to call Page.Validate myself (not that there probably aren't some good ones). Here is a contrived example from the help files.

Sub Page_Load
If Not IsPostBack
' Validate initially to force the asterisks
' to appear before the first roundtrip.
Validate()
End If
End Sub

I always do a check of Page.IsValid first thing in my button click events.

If Not Page.IsValid Then Return, if (for whatever reason) your client-side javascript didn't prevent the page from posting in the first place then the server validate
events will run.
You use Page.IsValid to make sure that the server validation didn't catch anything.

Thats very much fine my friend but my need is that i have 2 pages and want to valiadate

page1 by user name and password.....if the password is correct only then one should

reach on the next page.

Thanks very much for this information and please suggest me how can i do that?
