Is it possible to make sure that the value is a number when the user is
filling out a form by using RegularExpressionValidator?

I'm trying to use it, but I don't know how to build the right
ValidationExpression.

Or there's another easier way to do it?

Thanks in advanced,

Yes, you should be able to use a regex to confirm a value is a number. =
However, if need to confirm the value is an integer, it may be cleaner =
and simpler to use the CompareValidator or the RangeValidator. Both of =
these can do data-type check for integer.

Example:
<asp:CompareValidator runat=3Dserver Type=3DInteger =
Operator=3DDataTypeCheck />

Or:
<asp:RangeValidator runat=3Dserver Type=3DInteger MinimumValue=3D"0" =
MaximumValue=3D"1000" />

Using a regex, the pattern \d will match any single digit. You can =
match a positive number of arbitrary length with \d+
Example:
<asp:RegularExpressionValidator runat=3Dserver =
ValidationExpression=3D"\d+" />

Yes it is possible. But you should use the Compare validator. Set Type to
Integer and Operator to DataTypeCheck.
