Hi

I have a MaskedEdit Textbox as following:

<asp:TextBox ID="TextBox4" OnTextChanged="TextBox4_TextChanged" runat="server"></asp:TextBox>

runat="server"

TargetControlID="TextBox4"

MaskType=None

OnFocusCssClass="MaskedEditFocus"

OnInvalidCssClass="MaskedEditError" />

What I want that instead of the Mask="99/999/9999/99999/999" I want to allow the user to Enter characters also so the mask will be

99/***/9999/99999/999(asteriks is for characters),

if 9 is for numbers,what is the code for characters?

Also When the user finishes typing in the MaskedTextBox I want to query the database to see if the entered code is valid.In VB6 i used the lost_focus event for this purpose what is the alternative in ASP.NET?

thanks

Hi There,

1) Masking, Use A for alphabet

 MaskType="None" Mask="99/AAA/9999/99999/999"

2) Event, use OnTextChanged, this event will trigger when lost focus as well as the text has been changed. Make sure you set autopostback is true, or it will not trigger event.

<asp:TextBox ID="TextBox1" runat="server" OnTextChanged="TextBox1_TextChanged" AutoPostBack="true"></asp:TextBox>
