How to Create Paging and Sorting in Gridview in MVC.





Descriptin:-

In this Example we Explain that how to Create a paging and sorting in MVC.

What is MVC:-

            MVC stands for model view Controller.there are three part in the MVC so your all code are define separtely like in model the Database table are stored and in View only Desinging part are included in View part and your coding part are included in Controller part.so every thing are defined separtally.

What is Paging:-

                            paging means bunch of record and are used to navigate the record.each and every bunch can contain a number of record based on user that are defined by the user.

 What is Sorting:-

                  Sorting means sort the Gridview Row based on coloumn name either in ascending order or descending order.we can easily sort the record in gridview by just click on the coloumn name in gridview.

for example:-

             if you want sort the all employees records in ascending order with emloyees name then you just have to click on the employees name coloumn in gridview.
 
In this Example we craete a Gridview same like in asp.net Gridview control and in which we provide paging and sorting facility.in sorting is coloum wise when user click on coloum one then all data are sorted through coloum one.and also sorted if currentally in ascending order then it will automatically sorted in Descending order. If currentally is Descending then it will automatically sorted in ascending order.

To do this First you have to create a table with following structure.
