Slow page load - RadScheduler

Hi,

We are using RadScheduler to display a rota. The data per eah date is very minimal. However the page which containc RadScheduler control takes about 12-15 seconds to load completely before on can start working on it. The query which fetches the date is fairly basic and highly optimised. So we don't see any problem there.

Earlier on load, the control was defaulted to to display data for a month. Then it used to take around 20-25 seconds before a page loaded. But ever since we configured it to display data for 7-days, the time has come down to around 12 seconds.

What we conclude is that the javascript or html that the control brings alongwith it takes fairly long time to load.

Is there a way we can reduce the amount of javascript of html that is loaded. Or elase if you think there are other problems, can you just the solution?

Thanks

Ajax call Scheduler into modal popup

We have an MVC 3 application where we needed to use the Rad Scheduler. We basically render out the control and stick it into a view. This is working fine.

However now we have a situation where we need to render the scheduler to a modal popup. Basically in the modal we do an ajax GET request which grabs the rendered control and sets the innerHTML of the modal to the ajax response.

After setting the innerHTML all of the scheduler markup seems to be there including script tags and viewstate. The calendar is rendered in the modal, looks great. However it doesn't do anything. Click events aren't working, cant change months, etc.

My guess is that there are some DOM events or something that allow the calendar to work from the full page load but not from the ajax call. I haven't figured it out exactly. But my question is, is there some way to ajax load the control and then from the clients side trigger some code that causes the scheduler to run all of its javascript (or do whatever it needs to do) and start working?

I realize this was not the intended use of the control but any suggestions would be greatly appreciated!

IE Max StyleSheet Limit reached Message

We are currently using the RadStyleSheetManager in our application and have moved all of our styles into one style sheet. The only stylesheet not included in our main stylesheet is the jQuery Redmond.css stylesheet. We currently have EnableScriptCombine = True and OutputCompression = "True". This is all setup on the master page in our application. Our users are reporting that they are receiving the Max stylesheet message in IE when they are on certain pages.

One of the screens where this issue appears to be occurring frequently we have a RadTabStrip and a RadGrid. When the user clicks the tabstrip we are just re-binding the grid with a different datasource. There was no need to actually have seperate grids since it is the exact same on each tab the only exception is the filter being used on the datasource.

Users are reporting that if they switch the tabs or paging through the grids; if seems that the everytime the page is posting it appears that the same requests are repeatedly being made and this is causing the Max stylesheet error to appear ( not 100% sure that's what is happening but at least thats what I see when i open up the Developer Tool in IE and click the CSS tab I'm seeing a lot of request in the drop down for this particular page.)

Any guidance or help would be greatly appreciated in helping us resolve this issue.

If you need more information please let me know and I will be glad to supply you with anything you may need.

Close Window from itself

I have a page that opens a radWindow (called "radUserManager") and load the UserManager.aspx page:

<telerik:RadWindow ID="radUserManager" runat="server"

NavigateUrl="UserManager.aspx" Height="500" Width="950" Modal=true

Style="z-index: 7001" Behaviors="Close, Reload" Top="-500px"></telerik:RadWindow>

On UserManager.aspx, I have a radButton like this:

<telerik:RadButton ID="cmdCancel" runat="server" Skin="Windows7" Text="Cancel" Width="75px" OnClientClick="CloseWindow(); return false;" >

</telerik:RadButton>

The CloseWindow code looks like this:

function GetCommentRadWindow() {

var oWnd = GetRadWindowManager().getWindowByName("radUserManager");

return oWnd;

}

function CloseWindow() {

GetCommentRadWindow().close();

}

Problem is, the window does not close. Nothing seems to happen.

Custom text when item is highlighted with up/down arrows

I have some custom text that I am displaying in a radcombobox based on the following template:

<ItemTemplate>

US

<%# DataBinder.Eval(Container.DataItem, "AmountUSD", "{0:$####}")%>

=

<%# DataBinder.Eval(Container.DataItem, "Code") %>

<%# DataBinder.Eval(Container.DataItem, "AmountLocal", "{0:$####}") %>

</ItemTemplate>

However, when an item is highlighted with the up/down arrows, the DataTextField (AmountUSD) value shows. For example, the combobox item will show "US $20 = EC $54" in the list, but when highlighted, the combobox text will show "20.0000".

I would like to either have the combobox text show as the template text or not show at all.

This custom text is already stored in an attribute called "DisplayText". Is there a way to use that?
