Questions on UI for ASP.NET AJAX Forum

I am using RadAjaxManager and RadAjaxManagerProxy for achieving AJAX in my page. I have asp:PlaceHolder which have all dynamic controls and i want to refresh those set of controls on AJAX call. I have put that in panel which i have placed in div to get the fix region with scroll bar.

<div id="dvQuestionSection" class="QuestionSection" onscroll="SetQuestionSectionScrollPos()">
    <asp:Panel ID="pnlPhFields" runat="server">
        <asp:PlaceHolder ID="phFields" runat="server"></asp:PlaceHolder>
    </asp:Panel>
</div>

After ajax call gets completed, scroll position of div gets changed. And what i have noticed is, this happens especially when I have RadEditor control in place holder and it set the scroll position so that RadEditor comes visible.

I want to be on same scroll position where I am invoking ajax call.
Any direction on this will be a great help.

Thanks
Paresh

OnClientFileUploading args.set_cancel(true) behaviour question

Hi,

I have an issue where setting args.set_cancel(true) in the OnClientFileUploading event doesn't seem to cancel the upload.

I have a small working example of this.

The example checks that you are not uploading two files with the same name. Upon detecting that you are, it displays an alert and sets the cancel to true. I note however that when posting back, I still get a FileUploaded server event for each file, including the cancelled one(s).

How do I know that one of those is actually cancelled? What is the expected functionality of cancelling the upload through this method? All that seems to happen is the file indicator turns red but otherwise it seems it makes no difference to functionality.

Please help! :)

EnableLoadOnDemand

Hi,
I have a radcombobox where I have EnableLoadonDemand is True. When I type "America" in the dropdownlist, it searches first for all "A" then "AM" then "AME" and so on. For my project, getting data takes a while so each search makes dropdownlist slower. What I would like to do is after user type a letter or word, I want to wait for a second then go for search. so instead of making multiple trips to sever, it will make only 1 trip. Ofcourse, User will wiat for a second but that's better than multiple roundtrip to server.

Hope this makes sense.

Thanks in advance for youe help.

Export To Excel Layout Issue

So I have a Grid with a MasterTableView that contains a DetailTable, and that DetailTable contains a DetailTable. Everything is correct as far as layout indentation when it renders to the screen and when I export to pdf. But the problem is when I try to export to excel. When the spreadsheet opens the MasterTableView item is say 7 columns wide. The first DetailTable item is say 5 columns wide, and the second DetailTable items are 3 columns wide. And they appear like they are center aligned so it looks like an upside down pyramid. My client does not like this and I have tried for hours now to figure out how to make the item indentations look like they do in the pdf and screen but with no luck. Is there a setting or something to make the excel render correctly or is this a bug. Below will be my grid markup, and I'll attach an image of the spreadsheet so you can see what it looks like. Thanks for any help in this issue.

Dock Usability?

Does anyone have any experience or seen any reports about the usability implications of using Dock in their web applications? My partner and I are designing an app, but disagree about the use of dockable windows. Our users, are not technical people, but rather "regular" business people.

He wants our users to have the ability the customise their interface - a nice goal - however, I'm concerned that for non technical people it could be too confusing, and may make support much more complex.

Thanks for any insights you may have in advance!
