calling a javascript function in a radwindow

[Matthew Bishop]

Im trying to call a javascript function on the page created by RadWindowManager. To do this without the RadWindowManager you would do something like this:
'iframe1.helloworld();' or eval("iframe1.helloworld();");
from the parent page.

However, I cannot manage to do this using RadWindowManager.

Any suggestions on how I can do this?

Hi Matthew,

Here is how to call a Javascript function in a RadWindow from the parent page (code taken from the control's documentation, section RadWindow Client-Side): 

//Call a predefined function in opened RadWindow
function CallFn()
{
   var oWnd = $find("<%=RadWindowManager1.ClientID %>").getWindowByName("RadWindow1");
   oWnd.get_ContentFrame().contentWindow.CalledFn(); //CalledFn() must exists in the RadWindow's content
}

I hope this helps.

It certainly did, thanks. One thing I noticed though is that when I pass variables to the function, it will only accept one variable.
eg:
From main page
oWnd.get_ContentFrame().contentWindow.CalledFn('This is X','This is Y'); 

From target page
function CalledFn(x,y)
{
    alert(x,y);
}

Will only alert 'This is X'.
Whilst it is no problem since I just call back to the main page to get the variables, yet another function does get messy.

Is this a bug with the control?

Hi Matthew,

The arguments are passed correctly, however you cannot alert them like that - you can try this for yourself by testing the following example - the result will be the same.

<script type="text/javascript">
function calledFn(x,y)
{
    alert(x,y);
}
</script>
<button onclick="calledFn('one','two'); return false;">test</button>

More information on the comma operator can be found in varuous places in the Net - for example here:
http://www.webreference.com/javascript/reference/core_ref/ops.html


Try with alert(x + y) or alert(x + "  " + y) - this way you can alert both arguments.
