only allow numeric values on textbox

Hi,

You can use range validator and force user to enter only numbers. You can also set min. and max. values allowed. If don't want requiredfieldvalidator you can remove it.

<asp:textbox id="YourID" runat="server" Width="40px" ></asp:textbox>
<asp:requiredfieldvalidator id="ID" runat="server" ErrorMessage="Value required." ControlToValidate="YourID" ></asp:requiredfieldvalidator>
<asp:rangevalidator id="YourID" runat="server" ErrorMessage="Minimum 0 required." ControlToValidate="YourID" MaximumValue="999" MinimumValue="0" Type="Integer">*</asp:rangevalidator></TD>

hope this helps.

Put this in your Page_Load event, it will allow you to Input only numbers in TextBox..

TextBox1.Attributes.Add("onKeyPress","if ( (event.keyCode < 48 || event.keyCode > 57 ) event.returnValue = false;");

You should add a regularexpression validator for your textbox
with a regular expression \d+

Or you can derive your own control from textbox and only allow
input numbers

If you are using VB.Net you need to remove ";" from the line that I have posted, so include following line:

txtoperatorid.Attributes.Add("onKeyPress","if ( (event.keyCode < 48 || event.keyCode > 57 ) event.returnValue = false;")

If you want to allow for any number value, not just integers,
the simplest way is to use a regular expression validator.
But you have to change the validation expression though.
