[Solved] Speed, Loading issues in IE7 and IE6?

[Fred]

Wondering if anyone has suggestions for increasing the loading speed of a page I have.

It has over 50 fields. RadTextBoxes, NumerticTextBoxes, ComboBoxs, shared DatePickers..

And a Tab Control with controls on it.

In IE7 it seems to take them 20 seconds to load the page, where as another page using the Document Editor and RadTreeView only takes about 5 to 7 seconds.

In IE6 it loads faster then IE7, but then if they scroll down to the Tab Control they get an hour glass, and none of the fields load the data (whatever that means I haven't seen the issues yet in IE6)

So just wondering on general things I can do to speed up the page with all the Telerik controls all over it.

the total page size is about 650k. It was 850k, but then I dropped it down by switching to RadDatePicker and using a Shared Calendar and removing all the whitespace on the page using an httpmodule.

So at 650k page size a large pipe to the internet, it takes this user too long to load the page.  Vs the other pages that load in a bout 5secs.

There a way to cache things to the client when they log in? I'm thinking the speed problem is not the downloading of the page, but the processing of the page by IE to render the controls to the screen. How could I speed up that process?

Also, I should note, same page in FF takes 2 second lol. Unfortunately the clients are locked down to IE6 and IE7.

Doing a Trace, from Begin Render to End Render is 1.3secs, that normal?

Also have few comboboxes.

If I do an ajax post back save of some controls using the ajax manger, the Render area's take twice as long as the initial page load. So even slower when going back to server.

I'm finding that the slow part of the page, after making lots of changes is the anything I do in the TabStrip / MultiPageView area.

Ok the speed is at a normal fast speed again.

I only uses ComboBoxes and NumericBoxes where I needed them and used regular controls for other places.

Then added in the AjaxManager which helped a lot

Then changed the TabStrip to work like this post but I used the AjaxManager instead..

I'm not using on demand tabs, yet.

<telerik:AjaxSetting AjaxControlID="rtsRACTabs">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="rtsRACTabs" />
                    <telerik:AjaxUpdatedControl ControlID="rmpRACPages" />
                </UpdatedControls>
            </telerik:AjaxSetting>

<telerik:RadTabStrip ID="rtsRACTabs" runat="server"
                EnableViewState="false"
                ClickSelectedTab="true"
                AutoPostBack="true"
                Orientation="HorizontalTop"
                MultiPageID="rmpRACPages"
                Skin="Default"
                ValidationGroup="TabStrip">
...TABS...</telerik:RadTabStrip>
<telerik:RadMultiPage ID="rmpRACPages" runat="server" RenderSelectedPageOnly="true">
.... page views...
</telerik:RadMultiPage >

Hi Fred,

Another option in this case would be to use the RadInputManager to remove the numerous instances of the NumerticTextBoxes, if applicable. Other than that, the present approach which you are using is also correct, and I hope the performance is good at your end.

Best wishes,
