Notification on Interval from Web Service

[Peter]

Hi

 

im probably being a bit silly but i cant work out how to get this to work properly i want the notification to check on an interval , but get the data from a web service , but if there is no data from the web service i dont want it to pop anything up.

 

this is what i have so far

     <telerik:RadNotification ID="RadNotification1" Animation="Slide" runat="server" OffsetX="-20"<br>        VisibleOnPageLoad="true" OffsetY="-20" Width="250px" Height="80px" LoadContentOn="TimeInterval"<br>        WebMethodName="GetWeatherForcast" WebMethodPath="../Services/EclipseService.asmx"<br>        UpdateInterval="30000" AutoCloseDelay="1500" KeepOnMouseOver="true" RenderMode="Lightweight"<br>        VisibleTitlebar="false" Value="rainyState" EnableRoundedCorners="true" Skin="Office2007" OnClientUpdated="OnClientUpdated"><br>    </telerik:RadNotification>

 

and for the JS function

    function OnClientUpdated(sender, args) {
        var newMsgs = sender.get_value();
        if (newMsgs != 0) {
            sender.show();
        }
    }

 

it mostly seems to work , but i need it not to pop up anything when no data is returned from the web service ?

done some additional work and found that i should be using the get_content call

 

but i am getting an error Object doesn't support property or method 'get_content'

any help is appreciated.

Hello Peter,

Yes, you should use the get_content() method to programmatically understand whether the notification is loaded with no content and if so to cancel the continuation of loading via set_cancel(true) method. However, these methods are exposed in the OnClientUpdating event not OnClientUpdated.

You can find attached a simple demo that demonstrates how to implement the required behavior.
