Strange explanation, GridView shows up all elements correctly, but is stupid enough to tell that ther is no element at index -1 when you click it! Anyway the solution is simple, rebind the GridView. Share this: dgvTxn.DataSource = listTxns; dgvTxn.CurrentCell = dgvTxn[0, 0]; where dgvTxn is a standard DataGridView control. That final line in the above code causes an exception to be thrown with the message "index -1 does not have a value". Recently I was assigned to work on Datagridview . I bind the Generic list to the Gridview, in other thread I'm modifying the Generic list which is bounded. when I scrolling the Datagridview Control in UI, I'm getting the fallowing error
