Hello,

Using a reguklare Textbox in my ASP.NET form:

1. How do I only allow users to enter "-" and "/", no space between characters and only four characters, for example:
M-55 or M/55 but not M 55 or M$557.

2. How do I display a calendar box and save date selected to a textbox in the following format:
DD/MM/YYY?

Thanks,

Victor

How do I only allow users to enter "-" and "/", no space between characters and only four characters, for example:

a) You can use a regular expression validator if you want to make such entries "illegal" (but typeable).
b) You can use client script (javascript, e.g.) to intercept and filter keystrokes.

How do I display a calendar box and save date selected to a textbox in the following format:
DD/MM/YYY?
Get the value from the calendar box via standard method, set the text of the textbox using one of the ToString(string format) method (such as the one from the DateTime class).

Hello,

I looked at the examples but still not clear on how to implement them in my project. Can you please send me a small sample on how to use the calendar in an ASP.NET project.

Thanks,

Hi,
Below is the code, I was using to restrict certain characters, how do I modify it to only include the following to symbols "-" and "/" and no space between characters? Quickest would be to include all possible symbols in that list and exclude the two that I want, but, s a better way than including a long list of symbols in the code?

Dim ca As Char() = {"+", "$", "/"}
Private Sub TextBox1_KeyPress(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles TextBox1.KeyPress
        If ca.Contains(e.KeyChar) Then
            e.Handled = True
        End If
    End Sub

How do I include a calendar button next to my textbox and when I click on it to display the calendar to select the date and display date selected in the textbox in the format mentioned (dd/mm/yyyy). Can you please send me an example of the code.

Thanks,

Victor

Hi again,

How do I also control input in a Textbox, to only allow number and 5b characters in the following format : XX.XX?

Thanks,

It seems that your #1 question was answered by several people, and not by the person you credited.  Or did I miss it?

You are right. I'm truly sorry about that. Unfortunately I can't take back the credit, will be more careful next time.
