Answer 1

You are trying to access the DataGridView like an array, when you need to specify that you're looking in the rows and columns. Instead of

DataGridView1(2, DataGridView1.SelectedRows(0).Index).Value

you can write

DataGridView1.Columns(2).Cells(DataGridView1.SelectedRows(0).Index).Value

However, relying on SelectedRows is not the best way to do it. What if the user accidentally selected a few rows and clicked the bottom one?

Assuming your code is in a CellClick handler with

(sender As Object, e As DataGridViewCellEventArgs)

you should use the DataGridViewCellEventArgs to tell what row you're on instead of relying on SelectedRows:

Dim id As String = DataGridView1(e.RowIndex).Cells(2).Value
