There are different ways to edit record in pageblock table.The first one is select one record ,to which we want to edit and go to anather page by taking Id of that record and in that page edit it.After completing editing then click save buttom and finally returns to original page.
By this concept we can only edit one record at a time .If one want to edit only one field of that record still he had to anather page for edit .
Its a clumsy process.So that problem is solved by Inlineedit concept.By using InlineEdit we can edit single field on that page.After editing every field we have to save record.But this tip is about we can select as many records want to edit , Editing is also made in that page .
We dont have to go other page. After compliting all editing we to save records . For that concept I have used Wrapper class and Inlineeditsuppot. A wrapper or container class is a class, a data structure, or an abstract data type whose instances are collections of other objects.
This is concept may be known as RowEditing In salesforce…..!!!!
