How to display an empty value in NumericUpDown control?


I have a Windows Forms application that includes NumericUpDown control With Minimum and Maximum values set to (50:80) accordingly and step 1.

When form loads the NumericUpDown shows 50.

I know that NumericUpDown is for picking numbers and numeric types and always has a value, but is there any way to make it show empty when form loads?


Solution

  • You can't make default NumericUpDown control empty. NumericUpDown need a value to increase/decrease from. If 'empty' is only a matter of look empty when user see the form at first, then you can hack it by setting NumericUpDown's Text to empty:

    Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
        NumericUpDown1.Text = ""
    End Sub
    

    With that NumericUpDown1 will look empty, but NumericUpDown1.Value is still 50.
