Solution 1

You have two (actually three) problems.

1. You don't specify your units:

l5.Style["Top"] = "1361px";

or em or whatever

2. You need to set the position

labelId.Style["position"] = "relative";

where labelId = l, l5 etc. and relative is my best guess at the type of CSS positioning you want, YMMV.

3. Some of the co-ordinate numbers you are using are huge for a web page. A left of 8161px would imply your page is roughly more more than four screens wide for most users. I assume you are using these values to test, but there is a danger you will miss these labels when testing as they are so far off the screen without scrolling.

thx bro it works,but i have another problem which i retrieve coordinates from previous system database that was created according to desktop application coordinates.Do u have solution to map older coordinates to web base system

Glad my answer got you going again.
As for the mapping you just need to come up with a scaling factor (a standard figure to divide the desktop co-ordinate by) so the oringinal co-ordinates map to values within the normal bounds of your web page. You might also need to subtract an offset too, if the the desktop app starts at x=100 y = 50 for example, these need to be subtracted first.
