Hey everyone

i have a RadNumericTextbox inside grid edit form--
<telerik:RadNumericTextBox ID="txtQuantityE" autocomplete="off" runat="server" Skin="Hay"
                                                                EmptyMessage="Enter Quantity" SelectionOnFocus="CaretToEnd" ToolTip="Enter Quantity to place Order"
                                                                Culture="English (United States)" Height="14px" Width="141px" MaxValue="9999"
                                                                MinValue="1">
                                                                <NumberFormat GroupSeparator="" DecimalDigits="0" AllowRounding="true" KeepNotRoundedValue="false" />
                                                                <ClientEvents OnKeyPress="KeyPress" />
                                                            </telerik:RadNumericTextBox>
javascript --
function show(txtQuantityE, lblRate, lblAmount, Amount)
            {
               var txtQuantityE = $find(txtQuantityE);
               var lblRate = document.getElementById(lblRate);
               var lblAmount = document.getElementById(lblAmount);
               var Amount = document.getElementById(Amount);
               Amount.value = parseInt(txtQuantityE.get_value()) * parseInt(lblRate.innerHTML);
               lblAmount.innerHTML = parseInt(txtQuantityE.get_value()) * parseInt(lblRate.innerHTML);
            }
            function KeyPress(sender, args)
            {
                if (args.get_keyCharacter() == sender.get_numberFormat().DecimalSeparator) {
                    args.set_cancel(true);
                }
                if(args.get_keyCode() == 45)
                {
                alert("Enter non-negative numbers only");
                args.set_cancel(true);
                
            }
codebehind--
txtQauntityE.Attributes.Add("onblur", "return show('" + txtQauntityE.ClientID + "','" + lblRate.ClientID + "','" + lblAmount.ClientID + "','" + Amount.ClientID + "')");
is it possible to get the product on label on text change of textbox,by keypress event?....i want the text of label to change with text change of textbox.

Thanks
Amit

Hi Amit,

Using keypress will be a little cumbersome in your case. You can use setInterval, as explained here:
