Buttons are not performing postback

I am clicking the button, everything is set, runat server is there, id is there but still, the button just dont postback. Many times we do face this problem, specially with the newbies. Sometimes our page becomes so complex or say so distributed that you may get stick with failure of postback of one or more buttons.
80% of the time the problem will lies with the validators. If you dont define the validation group property for a section, each and every button on the page, whether it sits on master page or child page, will stop the click of buttons. Also we do copy paste the code many times from one page to another. Make sure that the validationgroup property is correctly set.

This is a basic question that should be clear in mind of every developer. Though this thing has been answered in many places, but i didnot found the collective ans that easily. I will try below to make the things simple and clear.

Normally when we store the session value for user we do some thing like this


User becomes the key for storing session and Customer class object becomes the value. This is just an expample as we all know that you can know you can store any type, content, value with a key in a session(Note that there are certain good practices or key pointers on what kind of data should be stored in session, will cover that in a seperate article later)

Classic problem between developers and UI designers

As a developer, you must have faced a classical issue, the UI guy says “dude the control that you have used got converted into table (<tr><td>) structure and it has screwed up my entire styling/css, i have to do a rework”. And the timeline has to be extended. This is a classic problem when we work in group, startup or as a freelancer. In big companies there a specialist to create UI, but at smaller scale becomes very crucial.

My suggestion to developers and designers, that dont hate .net in terms of UI. You are already provided with lots of setting with each control. Some examples are as below

1. Radio button list and checkbox list :
repeat layout : table, flow , unordered list, unordered list
repeatDirection: horizontal or vertical
repeatcolumns : enter the number :)

Just look for the following traps

  1. Look out for “if(!Page.IsPostBack)”
