Hi zohaibk,

You could also loop through rows and check each box in this way if not that much of rows.

    Dim col As DataGridViewCheckBoxColumn = Column1
    For Each row As DataGridViewRow In DataGridView1.Rows
      row.Cells(Column1.Name).Value = True
    Next
    'or
    For Each row As DataGridViewRow In DataGridView1.Rows
      row.Cells(Column1.Name).Value = 1 ' prerequisite: truevalue has been set to 1
    Next
