Postback Scroll on filters and sorts

[Mark]

Hey Telerik,

this has probably been answered before but none of the fixes I found seemed to work.

Basically I have a 3 grids in one page and they have quite a bit of data. When I sort/filter a certain column or update a row, 
the page does a postback and goes all the way to the top.

I tried MaintainScrollPositionOnPostback in the aspx page, I tried to set it in the page load and also in the web.config but that didn't work.
I also tried using javascript by having a 'onscroll' event. I tried that on document, window and the wrapping div and the event never got triggered.

The event gets triggered with onmousewheel though, but that wont work with the scrollbar/touchscreen, which I also need.

Is there a way to do a local postback or maybe change something in the grids to prevent going back to the top?

Thanks!

Does anyone have anything ?

It's due for next monday so I really need to fix this.

Hi Mark,

You can achieve this requirement by ajaxifying the grids:

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
    <AjaxSettings>
        <telerik:AjaxSetting AjaxControlID="RadGrid1">
            <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID="RadGrid1" />
            </UpdatedControls>
        </telerik:AjaxSetting>
    </AjaxSettings>
</telerik:RadAjaxManager>

Hope this helps. Please give it a try and let me know about the result.

Alright, it does work I just tried it. 

The only problem now is that in each of my rows I can click a link that opens a report and another one that opens a RadWindow.
Since I added the RadAjaxManager, they won't open anymore.

EDIT of my previous post:

Clicking on an item's link button triggers a server event that does a bit of logic to get data and then:

            Telerik.Web.UI.RadWindow newWindow = new Telerik.Web.UI.RadWindow();
            newWindow.NavigateUrl              = "PODetailsNew.aspx";
            newWindow.VisibleOnPageLoad = true;
            newWindow.Width                        = 1000;
            newWindow.Height                       = 750;

            rwmPODetails.Windows.Add(newWindow);

Okay so another update, I added the RadWindowManager to the AjaxUpdatedControls, which worked to open the RadWindows.
Concerning the Javascript to open the Report I used RadAjaxManager.ResponseScripts.Add(''the script'');

Only one more concern now:
The RadWindow still opens at the top of the page but the page stays at the scrolled position
This can be a problem since there are 4 grids and you can scroll to a point where you wouldn't see the RadWindow when it is displayed

Hi Mark,

You can use the client-side event handlers of the manager and try to apply the center or moveTo methods when the window is shown:

That should do the trick.
