title: How to update multiple rows using gridview in ASP.net on a SINGLE BUTTON CLICK?
body: <p>The functional requirement is to fetch the list of students (3 coloums) from database (SQL Server) and display it on the web page, along with a blank field in front of each row for entering data.  Next, to allow the user to enter marks scored by students in the test and update those in the database.</p>
  
  <p>Now, I know this can be done using gridview by having an Update Button Field as separate coloumn. But in that case there would be an update button in front of each row and user would need to click it for each student (more than 100). This is a tedious task for user.</p>
  
  <p>I want that user enters the marks for all the students and then click only 1 button, which would update all the rows. </p>
  
  <p>On button click event we can use foreach loop for GridViewRows, but please help me with user interface. How to make it possible?? How to use single button click instead of 'n' clicks??</p>
  
  <p>Can it be done using gridview? Or is there something else which can accomplish the task??</p>
  
  <p>Thanks</p>
