"autogenerate" columns in multi column combobox

I'm using a autocompleting and multicolumns radcombo box to produce an application.

Up to now I've hard coded the itemtemplate in the aspx page bt now I'm trying to roll it out a bit more dynamically.

Part of the application allows users to choose which database fields to include in the query so I won't know what to add to the <itemtemplate> until run time.

What is the best way to dynamically "autogenerate" the columns in the multicolumn combo??

Ajax + window modal

Hi,
i've got a question, because im new to asp.net. Im trying to port mine app from WPF to ASP.NET, but got few issues. Im doing full ajax app, and i dont know how to achiv such scenario:

1. Default.aspx with RadWindowManager and a DIV that will contain website later.
2. Login.aspx just a form with login, pass and a button (it appears in RadWindow)
3. xxxx.aspx after successful login

so basicly in Default.cs i got

protected void Page_Load(object sender, EventArgs e)

{

SessionUser sessionUser = (SessionUser)Session["User"];

if (sessionUser == null)

{

ShowLoginWindow();

}

ShowLoginWindow() just open a RadWindow and till that everything works fine. Than in Login.aspx i use RadAjaxManager with button control to get click. Mine question starts here
1. How can i close RadWindow form code-behind.
2. How can i know at code-behind Default.cs that Login Window is closed, so i can load a site into DIV?

Also how do you use modal window? Im not talking about lock screen, because there is a bool to make modal or not, but how can i do something at code-behind, than forward data to modal window, get data from window and continue to execute code.
Something like:

Window window = new Window();
window.MineString = "Something";
window.ShowDialog();
MessageBox.Show(window.OtherString);

Ofc i know it cant be achiv like i did, but need something for such scenario.

Thanks, for help.

Image Size/Width Detection

I am trying to figure out what to do when an image I upload to my database is smaller than my max height/width that I have setup for resize on upload.

For example, I have my resize utlity resizing all images to be no larger than 1000 X 1200 pixels and this works great with RadBinary because it "fits" them into my various objects (thumbnail, full size, screen size, etc) at my specificied sizes (for example full size = 500 pixels width). But my problem is sometimes I am supplied with photos that have already been resized to dimensions which are smaller than the ones I have setup for my project (for example I might be supplied with a 300 x 400 image). This causes the image to be streched when I am using radbinary on my page because I have my sizes preset to 500 width.

I would like to know if there is a way to detect the image size from the database, then see if it is smaller than my presets (500 px), if so, then it would need to show the image in its largest format size and if not, show it in my preset size format.

I found this article, but it is referring to using it in the grid, but I am not, I just have the files on my page.
