I've implemented the Yahoo-like AJAX scrolling in a grid. It works great. There's one small issue which I'd like to resolve. When the scroller is moved to the bottom of the grid and the additional records are retrieved, the grid is re-created (GridCreated fires) and the JS that I use to dynamically resized the ScrollHeight is executed. This causes the height of the grid to visibly change during the AJAX call.

Any suggestions on how to avoid this "flicker"?

Thanks

Hello,

Hello All,

I have a site that loads data intensive charts that take a while to generate.  In order to improve the user's experience, we opted to load the page (minus the charts), then fire an ajax call to begin loading the charts at that time.  Currently it is simply being done by a Timer whose Interval is set to 1 sec.

This works responsibly well on most machines.  However, we started having some errors where splitters would not resize initially, menus would not load completely etc.  For the most part the behaviour was random and worse on some machines.

I realized that the JS was not completly loading before the timer was kicking off.  The timer was killing the current runing js files.

So I changed the timer to a 5 sec delay and everything worked as adversied.

So my question is: Is there an event that gets fired once all of the Telerik JS is finished loading?  If I could tie into that, I could enable my timer at eliminate the generic 5 sec wait time for most users.

Thanks for any advice.

Hi,

I have a very simple site with a masterpage.
This site is just for demo purposes and some tests.

It has a masterpage - and is AJAX enabled.

Here the main layout

So I have a head with 2 areas.
A navigation line with RadMenu.
A content pane and on the right side a "news pane".
On the bottom is some place for a footer.
I guess a pretty common and normal layout.

Everything works until it comes to the rotator.
Here is the page - also very simple:


You can see this page on REMOVED - SOLVED
I changed the size of the imgPreview to make the things a bit larger.
The result is in REMOVED - SOLVED

With FF 3.0.5 it works as expected - at least when I turn of "PauseOnMouseOver" because this sometimes stops the animation.
It goes than into a state where it does not scroll - but when I enter with the mouse and go out again it scrolls for some frames than it stops again.....

But anyhow - I don't really need PauseOnMouseOver.
But when you whatch the page with IE 7 - it is in simply words "unusable".

The Rotator is not included in scrolling.
If you load the page it is below the containing div.
When you scroll down an click on an image - it is positioned inside the frame.
But scrolling scrolls only the imgPreview not the rotator....
If you scroll up and click again -- it is displayed again below the div.

I don't think this is what you mean when you say:

Wide Cross-browser Support
RadControls for ASP.NET AJAX provides a consistent experience across all the major browsers: Internet Explorer, Firefox, .....
:)

Just kidding - but help would be great!!

Regards

Manfred

Dear Sir,

In that, RadSchedule control in both web & win rad control's recurrence rule field 's (format) data is varying while inserting a new appointment. But i am using a single database (sqlserver 2005). Can i insert  same type of recurrence rule field 's (format) data in both.

Please reply as soon as possible..

Hello all -

I am new to using the Telerik controls and am encountering a problem that I cannot seem to find a solution to. It's probably a simple fix and am hoping someone can point me in the right direction.  I have added the RadAjaxPanel and a panel bar to one of my pages. Withing the ItemTemplate tags I have added a div with several labels and textboxes. When I look at the page in design view or through a browser the text for the labels does not appear? If I highlight the area in a browser I can see the text so it appears the its being rendered with the text color set to white. If in design view I set the skin attribute to "Default" then the text shows up.

Any thoughts?

Thanks in advance!
