Formatting number with leading zeroes

[dranko]

I have a textbox bound to datatable column(integer type). What user want is when number is for example 5, to show 0005, or 35 to show 0035 (4 places).
How to format textbox to get that.
I was trying this:

BrojOtprTextBox.Text.ToString("0000")

but it doesn't work.

You can try this :

Dim Result As Integer
Dim IsInteger As Boolean
IsInteger = Integer.TryParse(BrojOtprTextBox.Text, Result)
If IsInteger Then
BrojOtprTextBox.Text = Result.ToString("0000")
        End If

You can try this :

Dim Result As Integer
Dim IsInteger As Boolean
IsInteger = Integer.TryParse(BrojOtprTextBox.Text, Result)
If IsInteger Then
BrojOtprTextBox.Text = Result.ToString("0000")
        End If

Thanks Bob, that's what I needed.

Why not:

BrojOtprTextBox.Text = BrojOtprTextBox.Text.PadLeft(4,"0")

Yes, it does the same, but you have to make sure that you only have digits in your textbox.
