Been looking into this deeper.  In my attempts I wasn't able to modify the z-index of the dialog window in a modal scenario, with out some script.  The z-index that you set in CSS only applies for a non-modal scenario it looks like.  I'm not sure if there's a bug here or if that's the intended behavior, but I've fired off a couple of emails to verify.  Either way, here's a bit of trick javscript to force the dialog window to use a z-index that you want.  It replaces one of the WebDialogWindow private functions which is generally a no-no, but until I find a better way to do this through the public API, the script below will have to suffice.  I added mine to the pageLoad client-side function, so that it will get executed during the pageLoad event (fired by AJAX).  The only thing you really need to modify is the line where you see zIndex=100.  In the script included with the product this is 99999.

function pageLoad(args){ 

$IG.DialogMoveBehavior.prototype._doZ=
function(lid, elem, lidZ)
{
    this._newZ = this._oldZ = $util.getStyleValue(null, 'zIndex', elem);
    if(!lidZ)
        lidZ = $util.toInt($util.getStyleValue(null, 'zIndex', lid), 0);
    if(lidZ < 10)
        lid.style.zIndex = lidZ = 100; //z-index will default to 100 in a modal scenario
    if($util.toInt(this._oldZ, 0) <= lidZ)
        elem.style.zIndex = this._newZ = lidZ + 1;
    return lidZ;
};

}

sory for the basic question. I managed it. Thanks.

your script runs perfect. Thank you very much.

can you please specify " pageLoad event (fired by AJAX).  " , that will help me.

Thanks.

I have a modal webdialog window on a master page..

The combo box dropdown is onthe webdialog. When I click on the webcombo, the dropdown elements show BEHIND the webdialog, SO I move the webdialog and there it is. IF I close the webdialog the dropdown remains. WHen I click on an item it then disappears.

 

when using this script I get an error that $IG is not defined.

here is my code

 

 

 

<

 

 

ig:WebDialogWindow ID="WDLogin" runat="server" Height="300px"

 

 

InitialLocation="Centered" Modal="True" Width="444px"

 

 

StyleSetName="Default"

 

 

meta:resourcekey

="WDLoginResource1">

Gracias por la ayuda Tony. El script esta funcionando perfectamente.
