推荐答案

So, for each row, the RowdataBound is called and each time you are binding the other GridView, which is a very wrong approach.



You should, ideally, after the first GridView Loaded and rows are selected, execute block of code which loops through the Rows of first GridView and copy that row to second GridView.



After the loop, bind the second GridView.
