MaskedTextBox Question

I need a textbox that will accept values in the format x.x or xx.x (i.e. 6.7, 4.4, or 10.0). I tried using a mask of "90.0" and "09.0" but they each seem to require two digits to the left of the decimal How should this mask be coded

Thanks for the information. That is really a lousy design!

We almost never use masked text boxes for numeric values exactly for this reason. Masked text boxes are fine if you need a specific format (SSN, phone #'s, etc), but pretty shabby if you have multiple possibilities.

We've rolled our own numeric text boxes via the keydown and keypress events with much success (e.g. checking how many digits to the left of the decimal on keypress, and checking that the key was a period, numeric, or backspace in keydown.

Hope this helps,

I agree that the design is rather weak. However You can achieve specific formatting by using a textbox and then reformatting when you leave.

Private Sub TextBox1_Leave(ByVal sender As Object, ByVal e As System.EventArgs) Handles TextBox1.Leave

Dim TestStr As String = ""

TestStr = Format(Me.TextBox1.Text, "Short Date")

Me.TextBox1.Text = TestStr

End Sub

Private Sub TextBox2_Leave(ByVal sender As Object, ByVal e As System.EventArgs) Handles TextBox2.Leave

Dim TestStr As String = ""

TestStr = Format(5459.4, "##,##0.00")

Me.TextBox2.Text = TestStr

End Sub

These should provide a bit of a clue as to a possible way around the issue.

This seems to be by design. The documentation has a similar example:

(999)-000-0000

United States phone number, area code optional. If users do not want to enter the optional characters, they can either enter spaces or place the mouse pointer directly at the position in the mask represented by the first 0.
