is there a way for the maximum value of numericUpDown linked or depends on the value of textbox labeled AB?
for example the value of textbox labeled "AB" is 10, it automatically sets the maximum value of numericUpDown to 10.

You can simply add an event handler for the Leave event and set the Maximum property of the NumericUpDown in that event
Sub AB_Leave(sender As Object, e As EventArgs)
Dim value As Decimal
' Safety check, the user can type anything in the textbox,
' we accept only a decimal number
If Decimal.TryParse(AB.Text, value) Then
numericUpDown1.Maximum = value
End If
End Sub

It works! thank you so much for the answer, now my problem is if I type on the NumericUpDown a number that is more than the value of the AB.Text, a message error should appear.

like this: If numberUpDown.value > AB.Text MsgBox ("Invalid Data", MsgBoxStyle.Critical, "Inventory System" I dont know why error does not display, it only automatically adjust the value of numericUpDown to equals the AB.Text value

I am not aware of anything ready to be used in this context. Probably you should work directly with the keyboard events like explained in this answer stackoverflow.com/questions/17369670/… but then, what about the Copy/Paste operations? As you can see it is not easy to reach this level of control without direct support from the control itself. Another possibility is to subclass the control and this is another can of worms and you should weight the costs to implement it before going forward.
