title: ASP .NET accessing data of Gridview row and invoke procedure for a buttonfield coulmn row
body: <p>I am creating a simple web application.<br>
  But I am facing a problem with a Gridview that displays some data from the database in a column and i have another column with a buttons where I want to invoke a stored procedure.<br>
  However the stored procedure takes as input the value of the corresponding data in the other column, so my question is how to access the value of this column and pass it to the action listener of the corresponding buttonfield?</p>
