Getting Top/Left in OnClientDragEnd

[James]

Hi,

I'm looking into the OnClientDragEnd event of the radWindow control. I want to get the window to simulate a snap to grid. in the event, I've tried the using the following:

- sender.getWindowBounds().x
- sender.get_Left()

Both always return the position of the window before the drag. i've looked at the online demo, but it doesn't look at the co-ordinates. Is there another property I need to look at for the dropped left/top?

BTW: on the bottom of the screen for the demo, it mentions 2 parameters expected, but says "sender" is the tooltip, not RadWindow.

Regards

Bobby

Hi Bobby,

You are correct, and we will be investigating why the old value is returned at the point of OnClientDragEnd.
For the time being using a window.setTimeout will solve the problem for you:

function OnClientDragEnd(sender, args)
{
    window.setTimeout(function()
    {
        alert(sender.getWindowBounds().x);
    }, 0);
}

Thank you for pointing the issue to our attention.

Kind regards,

Hi,

I tried using the window.setTimeout mentioned, but I still get the coordinates of the window from before the drag.

Any help would be appreciated.

Hi Peter,

Mine seems to be working find with the latest version of the Telerik controls. Could you possibly post your code for the event handler and I'll compare it with mine?

function SaveState(sender, eventArgs)
{
    var bounds = sender.getWindowBounds();

    window.setTimeout(function() {
           clientSaveState.PerformCallback(sender.get_name() + "|" + bounds.x + "|" + bounds.y + "|" + bounds.height + "|" + bounds.width + "|" + sender.isClosed());
    }, 0);
}

    <telerik:RadWindowManager ID="RadWindowManager1" runat="server" Skin="Mac"
        VisibleStatusbar="False" VisibleOnPageLoad="True"
        onclientclose="SaveState" onclientdragend="SaveState"
        onclientresize="SaveState" MinimizeZoneID="pnlMinimize">
    </telerik:RadWindowManager>

I am running the latest version and this script still returns the previous location.  Any help is appreciated.

Hi Peter

I've noticed you're doing your getwindowbounds outside of the timeout function. I'm guessing this will still retrieve the old values. I've got mine inside the settimeout function so it'll probably get fired on another thread and get the correct value (e.g. below for yours):

function SaveState(sender, eventArgs)

{

window.setTimeout(function() {

var bounds = sender.getWindowBounds();       clientSaveState.PerformCallback(sender.get_name() + "|" + bounds.x + "|" + bounds.y + "|" + bounds.height + "|" + bounds.width + "|" + sender.isClosed());

}, 0);

}

Bobby,

That was it!  It's always something simple you overlook.  Thanks for the help.

I am glad to find a workaround, but this is still happening in 2010.1.415.40

Any plans to correct the issue?

Thanks.

Hello stoneym,

Yes, we will improve this in the future but for now I cannot give a exact timeframe because such change is not an easy task due to backward compatibility. For the time being I suggest either to use the timeout or Telerik's static client library to get the needed data.

Found this in the latest version, still.  Would be nice to get fixed!

Hi Barry,

Thank you for bringing this to our attention. This feature has been implemented and the desired functionality will be available in the next internal build which is scheduled for the beginning of the next week, hopefully Tuesday. It will also be available in the official release since Q2 2011 SP1 (which is scheduled for mid September) as well if you do not wish to use internal builds.


Kind regards,

Thank you.

I have the timeout workaround in place.  I'm not sure I would be permitted to use a preliminary build, so I'll wait until it's in a full release.  This code is currently in a prototype solution.  When I do the "real thing", I'll be happy to rely on this fix.

Thanks.
