Which line throws error? And what is the error?

However, at a glance, I have few recommendations. 

a) If you are using ASP.Net 4.0, use the ClientIdMode property of the web server control , and set it to a value like static. That will avoid you figuring out elements on the DOM using run time generated id's. You can then stick to the id's what you provide.
document.getElementById('ctl00_ContentPlaceHolder1_'+ctrl).style.backgroundImage;  

var lbl = document.getElementById('<%=lblseat.ClientID %>');

b) There is an unused parameter in your funciton called "thil". What did you intend to use this for? If it was a typo and you intended "this" - that would be more helpful. 

Hope this helps.

YOu can get dynamic cell by following ways.

First you need to assign id for that cell while creating cell, after that use this code to get cell-

document.getElementById("id").value

Second can assign any css class so that you can access like this-

var cell= $(".classname");
