Check all boxes in a datagridview (Resolved)

I am trying to check all the text boxes in a datagrid view with this

VB Code:

Dim ctl As Control
        Dim cbx As CheckBox
        For Each ctl In Me.dgvPosiPay.Controls
            If ctl.GetType Is cbx.GetType Then
                ctl = DirectCast(ctl, CheckBox)
                If ctl.Checked = False Then
                    ctl.checked = True
                End If
            End If
        Next

I am getting the error 'checked' is not a member of 'System.Windows.Forms.Control'. and it is underlining the ctl.checked in the second if statement. I am pretty sure my problem is with the Me.dgvPosiPay.Controls part of the code block but I am not sure what the correct syntax should be.

VB Code:

For Each ctl As Windows.Forms.Control In Me.dgvPosiPay.Controls
            If TypeOf ctl Is CheckBox Then _
                DirectCast(ctl, CheckBox).Checked = True
        Next

Although, I'm pretty sure that this won't catch them. You're going to have to iterate through your datagridviewcells to find them.

This may not be the most elegant way to accomplish my goal but it worked so I am posting it so that others may use it.

VB Code:

Private Sub CheckAll()
        Dim j As Integer
        Try
            For j = 0 To ds.Tables(0).Rows.Count - 1
                dgvPosiPay.Item(6, j).Value = CheckState.Checked
            Next
        Catch ex As Exception
            Throw New Exception(ex.Message)
        End Try
    End Sub
