Regular Expression

[sonia sardana]

I want to enter only characters in textbox not numbers.For dat I use Regular Expression Validator,But even after dat numbers are entering.

<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox></td>
                     <asp:RegularExpressionValidator ID="regexpName" runat="server"     
                                    ErrorMessage="This expression does not validate." 
                                    ControlToValidate="TextBox1"     
                                    ValidationExpression="^[a-zA-Z'.\s]{1,40}$" />

I m take the help from the below site
http://msdn.microsoft.com/en-us/library/ms998267.aspx#paght000001_usingaregularexpressionvalidatorcontrol

tell me one ting more frnds,we have grab the ValidationExpression or there is any logic behind it,I m just grabbing it.

That validation happens server side so you can enter any data you want but on the postback it will fire off and invalidate the data. Is that what you were asking?

You should be able to use "^[a-zA-Z\s]*$" to match only characters and white space

I want the code similar to dat

Private Sub TextBox1_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles TextBox1.KeyPress
        If Asc(e.KeyChar) >= 48 And Asc(e.KeyChar) <= 57 Then
            e.Handled = False
        Else
            e.Handled = True

    End Sub

There is no point in mocking each other, you are both on same boat for similar reasons. So better to do something about it...

Also take it as friendly warning against flaming-wars.
