Code behind for Button Click in Datagridview Windows App

Hey there.

This is for a windows App made in VS2008.
I've added a button column in a datagridview, when clicked I would like to get the ID of the record selected. The ID of the record is the second column along, next to the select button. Been playing around with findcontrol but I'm not getting very far.

You can always use the DataKeynames and put the recordID in as the key.  Then you should be able to say

dim myID as string
myID = DataGridView1.Rows(e.rowindex).cells(1).value.tostring

BTW...Ignore the first part about DataKeyNames.  I started thinking about GridView with web stuff, not the DataGridView.  Sorry about that if it was confusing....I just went the wrong way.  You can just keep the DataGridView the way it is and use this.

How do I access the button though if it is made at runtime? I need code for finding that control, sorry, my fault, didn't make that clear enough in the question.

Came back to this to refresh my memory, in case anyone else comes across this and is stuck heres the code for determining which column was clicked:

Private Sub SearchResultsDataGrid_CellContentClick(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles SearchResultsDataGrid.CellContentClick
        If SearchResultsDataGrid.Columns(e.ColumnIndex).Equals(SearchResultsDataGrid.Columns(0)) Then
            'Insert your code here, assumes that your button control is in the first column.
        End If
