Where in the page lifecycle do stylesheets get loaded?

Hello,

I've created a site management system that has a base theme that is loaded via the pages directive in the web.config:

    
            <pages ... styleSheetTheme="Base">...</pages>

Then, to customize the look and feel for an individual site, I reference a theme in the Page_PreInit method:

    
            Me.Theme = "SiteTheme"

This works great. Anything defined in the Base theme gives you a standard appearance for any given component of the system. However, if you want to override the look and feel for an individual site, you can declare the same CSS definitions inside the Site Theme.

If I were to use the StyleSheet Manager to combine CSS files, when would they get loaded. My goal would be to manage all of the Base theme information with the StyleSheet Manager and still allow them to be overridden by the Site Theme.

Another side question: Would the StyleSheet Manager help beyond just combining all of the CSS files in my Base theme into a single CSS file?

Thank you.

OnClientSelectedIndexChanged with only RadComboBoxItem

Greetings,

I create a RadComboBox at runtime based on a user's selection of items in a grid. As the user selects items in the gird, I add an entry to the RadComboBox. The RadComboBox serves as a 'breadcrumb' strategy to move the user back to a position in the grid based on what they've selected in the RadComboBox. I use the OnClientSelectedIndexChanged event to reposition the user's location in the grid. My problem is this strategy fails when only one item is found in the RadComboBox. Clearly, OnClientSelectedIndexChanged won't work because they can never change the selected item. Can anybody suggest a strategy to avoid this problem or to overcome it? It would be nice to handle a RadComboBoxItem click event but I don't see that as supported. I could add a blank item to the combo box, but it does not meet user requirements. Any suggestions would be appreciated. Thanks.

Often, the user want to add more than one data at the time so I put 15 lines which are in edit mode. The user can enter 3 rows and then click on the "importer tous" button which valid if the values are ok. If they are, it's working fine. But if only 1 is not good I put it in a variable "CodePermInvalide" and redirect to an error page which display the CodePermInvalide value. Then I got a button on my error page like this:

    
            <A HREF="Javascript:history.go(-1)" >Retour</a>

When I click on this link, I'm back to my first page and I see all my 3 records, but I would like to see only the values which are not good. It insert the good value in my database so I would like to not see them when I come back to the first page.
Hope that make sense. If you need more informations, please be free to ask as I don't know if I'm clear enought.
Thank you!

Issue with drag and drop in IE6

Hi guys,

I have enabled the client side, drag and drop functionality on my page.
The treview is populated in the code behind and the nodes have a css class applied to them based on their type. One of the types has a blue border around the text.
When I drag this type of node on top of a textbox, in IE6 only , while I drag it, it shows a huge box with the blue border around it and it only dissapears once I drop the text in the textbox.
In any other browser the blue border does not show, only the text.
Any hints how to get rid of it ?

optimized method for determining if a RadGrid, RadList or RadTreeview has a selected item in it

If I want to determine whether a particular Rad Grid, Rad List or RadTreeview has an item which is selected (or checked node in the case of Rad TReeview), I can use the inherent selectedItems or checkednodes properties that these controls expose. However, to determine if a single item is selected, it is not necessery to return all the selected items. Therefore it would seem to me, that a more efficient method of determining whether an item is selected is to loop through all the items and if you come across one which is selected, return true (ie exit the loop) This would be the case unless Telerik used some sort of optimization technique for storing the selecteditems collection without looping through the entire set to setermine it. So, my questions is, does this kind of optimization exists, or is my method of looping instead of using the inherent selecteditems collection a more optimized way of determining whether an item has been selected.

On a related note, is there a way to get a list of all the nodes in a treeveiw without actually traversing the tree in a recursive fashion (ie is there some sort of optimized method of obtaining the full node list)

Issue with opening RadWindow Inside another RadWindow

Hi,

We are using radwindow control of Prometheus Q2 2009 version. We have a requirement display some data in the radwindow when a button of the page is clicked. In the radwindow we can save and edit some data. While saving if mandatory fields are not entered a alert should be displayed to the user. For displaying the alert we use radwindow.

The problem is, when opening a radwindow from another radwindow, the popup is not getting displayed.

I tried with code below, which display the rad window and but not in the front of the first opened radwindow.

var parentPage = GetRadWindow().BrowserWindow;

var parentRadWindowManager = parentPage.GetRadWindowManager();

var wnd = parentRadWindowManager.open("../../Shared/AlertPopup.aspx", "radAlertWindow");

wnd.setSize (300, 150);

wnd.SetModal(true);

return false;

Is there any option to make the radwindow open from another radwindow and display it inside the first opened radwindow. (as "Modal" window).

Thanks
