Hello Jeevitha,

Since you are using RadControls for ASP.NET AJAX version, use the get_value()/set_value() methods for getting and setting the value from client code.

ASPX:

<telerik:RadNumericTextBox ID="textBoxVarFirstChildR" Width="75px" MaxLength="8"

runat="server">

<ClientEvents OnBlur="duplicateFirstChildR" />

</telerik:RadNumericTextBox>

<telerik:RadTextBox ID="textBoxVarFirstChildNR" runat="server">

</telerik:RadTextBox>

JavaScript:

<script type="text/javascript">

function duplicateFirstChildR(sender, args) {

var textBoxVarFirstChildR = "<%=textBoxVarFirstChildR.ClientID %>";

var textBoxVarFirstChildNR = "<%=textBoxVarFirstChildNR.ClientID %>";

var fValue = $find(textBoxVarFirstChildR).get_value();

$find(textBoxVarFirstChildNR).set_value(fValue);

}

</script>

 

The following documentation shows the most important properties/methods of the RadNumericTextBox client-side object:

Hello Jeevitha,

You are not using the correct API. SetValue() is a method of the old ("classic") RadNumericTextBox. Now you have to use set_value().

http://www.telerik.com/help/aspnet-ajax/input_clientsideradnumerictextbox.html

In addition, it is better and more convenient to subscribe to OnBlur like this:

<telerik:RadNumericTextBox ID="RadNumericTextBox1" runat="server">
    <ClientEvents OnBlur="duplicateFirstChildR"  />
</telerik:RadTextBox>

http://www.telerik.com/help/aspnet-ajax/input_clientsideonblur.html

In this way you will have the textbox client object as a parameter (sender) ready to be used (no need to execute $find() ).
