Urgently Require working asp.net 2.0 control which will essentially implement the funcationality given below -
this needs to work correctly on all browsers, IE 6.x, IE 7.x, FireFox 1.5.x, 2.x, Opera 7.x + etc.
GOOD news is - this functionality is available in numerous other implementations
e.g.
[login to view URL] ( open source )
[login to view URL] ( free trial )
We essentially need to have it tested and enhanced as needed to work on all environments above withOUT FAIL
1) move items from the left listbox to the right - using javascript only, or server side if javascript disabled on browser etc.
2) no duplicates on right, preferably not on left either
3) support data-binding
4) maintain values across postbacks
5) have buttons to move selected, All from left to right and vice-versa
5) fyi - the left list box will be bound to different tables based on other controls
6) custom text to be displayed on the top of left and right listboxes
If you've it working, send me working code along with the test harness which tests the functionality above, the 1st person to post the working code gets the project - $30 fixed
