View 1 Replieshow to bind dropdown list using select query from Database in MVC4.
same like the below code
The web page I am trying to (slowly) build should allow users to add whichever user controls they want on their page, and order them whichever way they like. This is saved in a database.
So each user could have a different number of controls on the page.
This is the design code, at the minute the user controls are fixed and are not loaded dynamically. They user controls are stored in 'blocks' which look like widgets on the page and can be dragged about to different columns. For each user the layout is stored in the DB i.e. which blocks are in column 1 and which blocks in column 2 etc.
How could I change this so that it can create a 'block' div for each user control returned from the database and put the user control in that block and in the right column?
