@kinjal what is the use of using compare validator here??
and with what yopu are comparing the value?? your answer is
absolutely wrong.
If we want to allow only integers into a textbox then use
"^\d{0,9}" expression.
ex: <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
<asp:RegularExpressionValidator
ID="RegularExpressionValidator1" runat="server"
ControlToValidate="TextBox1"
ErrorMessage="RegularExpressionValidator"
ValidationExpression="^\d{0,9}"></asp:RegularExpressionValidator>

You will also use ajax FilteredTextBoxExtender and in filter
type allows only number like this
<asp:ScriptManager ID="ScriptManager1" runat="server" />
<asp:TextBox ID="TextBox1" runat="server">
</asp:TextBox>
<asp:FilteredTextBoxExtender
ID="FilteredTextBoxExtender1" runat="server"
TargetControlID="TextBox1" FilterType="Numbers">
</asp:FilteredTextBoxExtender>

Answer / anjaan
Three events are triggered when a key is pressed and
released:
keydown
keypress
keyup
The keydown event occurs when the key is pressed, followed
immediately by the keypress event. Then the keyup event is
generated when the key is released.
In order to understand the difference between keydown and
keypress, it is useful to understand the difference between
a "character" and a "key". A "key" is a physical button on
the computer's keyboard while a "character" is a symbol
typed by pressing a button. In theory, the keydown and
keyup events represent keys being pressed or released,
while the keypress event represents a character being typed.
