Here are two possible solutions to your issue. The first is based more on your original code, which I wasn't 100% sure which event you were targeting so I couldn't test it:

    Dim currentItem As ToolStripMenuItem = DirectCast(sender, ToolStripMenuItem)
    Dim parentItem = DirectCast(currentItem.OwnerItem, ToolStripMenuItem)
    For Each ctl As ToolStripMenuItem In parentItem.DropDownItems
        If ctl.Text = "Status" Then
            For Each dropctl As ToolStripMenuItem In ctl.DropDownItems
                If dropctl.Text = ListView1.SelectedItems.Item(0).Text Then
                    dropctl.Checked = True
                Else
                    dropctl.Checked = False ' Ensure that you uncheck a previously checked status
                End If
            Next
        End If
    Next

Next is the actual code that I used to test this functionality. I used the Opening event for the context menu to make this work. This may not work for you if you are reusing the same context menu for different columns or controls but if not then I would recommend this approach:

Private Sub ContextMenuStrip1_Opening(sender As Object, e As System.ComponentModel.CancelEventArgs) Handles ContextMenuStrip1.Opening
    If ListView1.SelectedItems.Count > 0 Then
        For Each ctl As ToolStripMenuItem In CType(sender, System.Windows.Forms.ContextMenuStrip).Items
            If ctl.Text = "Status" Then
                For Each dropctl As ToolStripMenuItem In ctl.DropDownItems
                    If dropctl.Text = ListView1.SelectedItems.Item(0).Text Then
                        dropctl.Checked = True
                    Else
                        dropctl.Checked = False ' Ensure that you uncheck a previously checked status
                    End If
                Next
            End If
        Next
    Else
        e.Cancel = True   ' Don't show the context menu if no row was clicked on
    End If
End Sub

In your original code you were only looping through the parent menu items. In this updated code it looks for the parent item 'Status' and then loops through the child items to find the status you need to check.
