Matrix algorithm for rendering XtraLayout designs into Web UI
In the past post on using XtraLayout component by DevExpress as a simple but powerful run-time designer I’ve mentioned rendering designs into Web UI. Here’s simple recipe for the matrix algorithm that is actually used to render XtraLayout-generated form designs in web UI of xLim 2 implementation.
This implementation does not require creating groups for every logical section like it has been done in XAF Web UI (and defining some custom orientation direction there) - all group contents sit within one table. Additionally this makes the designs reusable for WPF, Windows.Forms and Silverlight UI rendering (xLim 2 compatible renderer prototypes already exist for the first two).
Basically the UI rendering process happens in two steps. First, we check out every single control in the group and register its coordinates. We are only interested in unique X and Y values at this step.
Then, we count number of unique non-zero X values (that’s the number of columns in our table) and number of unique non-zero Y values (that’s the number of rows in our table). After that we calculate the sizes of these columns and rows (derive them from actual X, Y values). Widths will get sizes in percentages, since normally we want our forms to resize with the browser window.
In second pass we simply render all the controls into cells of the HTML table, while assigning appropriate RowSpan and ColSpan to these cells.

Is XLIM open source? and if it is can I download it.
If it’s not open source can you help me out with using forms authentication with XPO.
In the Gateway code you have a line of code.
//FormsChannel(new BinaryClientFormatterSinkProvider(), new BinaryServerFormatterSinkProvider(), new CookieCollection { _service.Cookie })
It’s look like you have already implemented forms authentication.
Can you give some advise on the pro an cons on using XPO with IDataStore. If I use IDataStore I don’t have to create a WCF layer on my model. And i can create a click-once application and have it running with tcp or http.
Martin,
I’ve tried to reach out for you by email, but my message got rejected. Will put the answer into the blog.
