Valdate Textbox to accept only Digits using Javascript.
Use this function on "keyup" event of Textbox.
Javascript:
function isDigit(evt) { var charCode = (evt.which) ? evt.which : event.keyCode if (charCode > 47 && charCode < 58) { return true; } else { return false; } }
aspx:
asp:textbox id="TextBox1" onkeyup="return isDigit(event)" runat="server" width="238px"
