I have 5 RadNumericTextbox, but I need when the user clears the input area it must always have a default value of "0", I don't need a validator, only I need before the callback is made the RadNumericTextboxes are filled with this default value.

Thanks.

Hello,

One suggestion would be attaching the 'OnBlur' client event and resetting the textbox value to zero when user clears the value. Here is the example.

ASPX:

 
<telerik:RadNumericTextBox ID="RadNumericTextBox1" Value="0" runat="server">  
    <ClientEvents OnBlur="OnBlur" />  
</telerik:RadNumericTextBox> 

JavaScript:

 
<script type="text/javascript">  
    function OnBlur(sender, args) {  
        if (sender.get_value() == "") {  
            sender.set_value("0");  
        }  
    }  
</script>

Thanks.

One more question, the code you share works fine, but I have a radnumerictextbox with autopostback=true. Without your code, the loading image shows(before) and hides(after) the postback, but with your code the images shows(before) and it still shows(after) the postback.

Can you help please?

This is the code for the panel loading:
        <telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel3" runat="server" Skin="" Transparency="30" OnClientShowing = "fnS" OnClientHiding = "fnH" MinDisplayTime="1000"
            <div class="loading"
                <asp:Image ID="Image1" runat="server" ImageUrl="~/img/loading1.gif" AlternateText="loading" /> 
            </div> 
        </telerik:RadAjaxLoadingPanel> 

The javascript code is:
function fnS(sender, args) { args.get_loadingElement().style.border = "1px solid grey"; args.set_cancelNativeDisplay(true); $telerik.$(args.get_loadingElement()).show("slow"); }  
 
function fnH(sender, args) { args.get_loadingElement().style.border = "1px solid blue"; args.set_cancelNativeDisplay(true); $telerik.$(args.get_loadingElement()).hide("slow"); }

Hello,

I hope the aproach of explicitly showing/hiding the RadAjaxLoadingPanel in OnRequestStart/OnResponseEnd methods will help you in achieving this.

The following documentation describes more on this topic:

Show and hide loading panel explicitly

Shinu.
