title: How to add a FooterRow to a Gridview which has no value initially
body: <p>I have a Gridview in which no rows populated initially. means i am not setting any datasource to gridview.I have to populate gridview by adding footerrow.I have given visibility of footerrow as true.So one error is coming as 'Object not set to an instance of an object'.what may be the reason for this? Can anybody help?</p>
  
  <p>Actually i need to add data into the Gridview through the FooterRow.After inserting a few records,i need to insert this data into the database.So, i want this Gridview only to insert data into the database.For a particular "FileID", i have many records,thats why i am using Gridview.Is there any other method for this?</p>
