[Hk]

hi,
i want to simply invoke radAlert(msg) from script:

<script>
function lala(){
msg="hey";
radalert(msg);
}
</script>

but it doesn't seem to work. is this the right way?

Hi Hadar,

To invoke RadAlert or any of the other predefined RadWindows you must first add the RadWindowManager to your page and then you will be able to use them.
More details for predefined dialogs can be found here.

Hi,
I have already defined a RadWindowManager:

<telerik:RadWindowManager id="RadWindowManager1" runat=server skin="Vista" EnableEmbeddedScripts="true"></telerik:RadWindowManager>

before I made the question, therefore it remains..

Hi Hadar,

How do you call the lala() function? For example yu can try with <button onclick="lala(); return false;">test</button> - that should work.




Cheers,
Hulky

Hi Hadar,

The rovided code seems to be correct when you want to call radalert. I tested it and it is works as expected on my side. I am not sure what is your exact setup and how you call the function "lala()". For your convenience I attached a simple web page with my setup that you can use as start point.

I will describe logic of the project :

• attach the showRadWindow() to the OnClientClick event in asp:Button declaration e.g. :
  

  <asp:Button ID="Button1" runat="server" Text="Button" OnClientClick="showRadAlert(); return false;" />

• insert "return false;" statement after attached showRadWindow() function. This prevents the postback when button is pressed.
• implement the function e.g. :
  

  <script type="text/javascript">
     function showRadAlert()
     {
        var message = " RadAlert dialog";
        radalert(message);
     }
  </script>

If you still experience the problem, please modify the attached project to demonstrate your setup, open a new support ticket and send it back to me. Once I receive it,  I will do my best to help.

Best wishes,

Hi Fiko,
As I mentioned, i'd like to invoke the method not thorugh a button click - I want the alert to be displayed as the page loads.
For some reason I get this error when I try to run your script (I've opened it as an AJAX 1.0 Enabled solution):

'~/Telerik.Web.UI.WebResource.axd' is missing in web.config. RadScriptManager requires a HttpHandler registration in web.config. Please, use the control Smart Tag to add the handler automatically, or see the help for more information: Controls > RadScriptManager

This is what i meant:
 <script type="text/javascript">
        function showRadAlert()
        {
            var message = " RadAlert dialog";
            radalert(message);
        }
        showRadAlert();
    </script>

Hi Hadar,

RadScriptManager needs an HttpHandler to be declared in the application configuration file to operate properly. This can be done through the SmartTags of the control. Please open the page in Design mode. Click on the smart tag near on your RadScriptManager and choose Register Telerik.Web.UI.WebResource.axd. Check out the folowing link for more details.
RadScriptManager

Thanks,
Shinu.

thanks,
yet my original question about invoking the radalert as I shown in my previous post, is not answered... :)

Hello Hadar,

I hope you want to display RadAlert when the page loads. You can try the below code snippet to show RadAlert on page load. ie, call the RadAlert from "pageLoad" function.

JavaScript:

<script type="text/javascript">
function pageLoad()
{
    var message = " RadAlert dialog";
    radalert(message);
}
</script>

Thanks.
Shinu.

Shinu,
not exactly, on server side I enable / disable the call to the "lala()" function. it means that sometimes

<script language="javascript">
lala();
</script>

is rendered, according to server side issues, and sometimes it doesn't.

I will "patch" it and render a full pageLoad call, I just wondered why a simple call as aboce won't simply invoke as the page rendered and loaded.

Hi Hadar,

The error message that you get is pretty self-explanatory. Did you follow the instructions in the error message?

As for showing radalert from the server, I believe that the following KB will be of help:
http://www.telerik.com/support/kb/aspnet-ajax/window/calling-radalert-from-codebehind-all-versions-of-radwindow.aspx

In addition, if you want to keep the client-side logic that you already use, you should call the function in the ASP.NET AJAX's pageLoad() event:

function pageLoad()
{
    var message = " RadAlert dialog";
    radalert(message);
}

All the best,

That won't work for me, because i have to wait untill several controls are loaded and read their text. If i try to do it on the pageload, the controls are still not loaded and they are null.

I just want the radalert simply invoke without any outer function! just as the script renders..
