Hi,

I have been given an assignment. Which is as per follow:-

Create a VF page 
This page contains list of contacts.
By default these records are not editable.
Each record has a checkbox.
If user clicks on a checkbox, then corresponding record will become editable.
User can modify that reocrd
Like that user can select multiple records and can modify them.
After changes, save all only those records which are editable. 
After saving the records refresh page and display updated record.
All checkboxes now should become unchecked.

I have create a VFpage and a controller for that but i unable to get desire output.Vf page code is as shown
<apex:page controller="BulkUpdateController">
<apex:form >
   <apex:actionFunction name="selectCheckBox" action="{!selectCheckBox}" rendered="block">
   <apex:param name="a" value="" assignTo="{!selectedCheckBox}"/>
   </apex:actionFunction>
    <apex:pageBlock >
     <table>
        <tr>
            <th>First Name</th>
            <th>Last Name</th>
            <th>Email</th>

I have created a custom button named addStudent  on class detail page. When i click on this button a pop window open.In this pop window there is a text box to add student name and a save button to save student of that class.I want that when i click on save button the exitsting window with text box and save button should be closed as soon as i click on that button and a student detail page open in place of class detail page.

How can we apply multiple searching using one searching button?

For example we have three text boxes and one searching button.Using that button how can we search using all three criteria.
