Hey everyone,

I have this code where I am trying multiply values from a textbox and label - want to show this value on a label on OnBlur event.
<script type="text/javascript">
           function FillAmount(sender, args)
               var txtQuantityE = $find('<%= txtQuantityE.ClientID %>');
               var lblRate = $find('<%= lblRate.ClientID %>');
               var lblAmount = $find(txtQuantityE*lblRate).get_value();

<telerik:RadNumericTextBox ID="txtQuantityE" runat="server" Skin="Office2007" EmptyMessage="Enter Quantity"
                                                        SelectionOnFocus="CaretToEnd" ToolTip="Enter Quantity to place Order" Culture="English (United States)"
                                                        Height="14px" Width="141px">
                                                        <ClientEvents OnBlur="FillAmount" />

Does not seem to work. Please help...

Solution 1

Well, assuming the Client event is raised, looks like this line is not correct:
var lblAmount = $find(txtQuantityE*lblRate).get_value();
Use DEBUGGER and you will get it easily.

It should be something like: txtQuantityE.value * lblRate.text
Verify and see. You already have your textbox and label objects, use them directly. Once done, find the amount control and assign the value.

Also one more thing, To do any airtmetic opertation, first you need to change in number. So do something like this

Number(txtQuantityE.value) * Number(lblRate.text);

Please make sure the entires are number else it Number() method will return null or undefined
