In my post, I explained how we can create a simple wizard using jQuery. In this post, we’ll see how asp.net gridview can be displayed in wizard format. Sometimes, gridview is used to take input from user when multiple fields are required many times. It is not user friendly, We can use wizard but not easy to handle on server side as in gridview.

In my post, I discussed different client side APIs and Methods of asp.net validator Controls. Now suppose if you have customized validation on client side, what’ll happen on server side? We need to do same on server side. Let’s understand this step by step by taking same example. Suppose you have to disable password’s requiredfieldvalidator when ‘Allow me‘ checkbox is true.

Now on server side button click, if you validate and check for isValid, it is always false and you will see error message in validationsummary even if checkbox is checked. Client side bypasses validation but on server side it’s stucked and our object is defeated. …
