problem in hide image control in datalist

it is right

here when i want edit my code i deleted by mistake

i correct it but it didn't show div  anywhere 

Rebuild the solution.., and let me know by running the proj what kind of error does its throwing ... ? Because your code is running as per expected on my machin. ... I wonder y its not working on your machin ... ?

ok i rebuild it but there wasn't any error

problem is that it didn't show div anywhere when i delete code and use div like this

<div id="Dart1_I1">

it show div but when i use your code it didn't show div even there was image in database

Verify in Database because it was very wl tested.

is there other way ?

i tested it but again didn't work
