hey there, here is my code and i'll explain my issue below it. 

<pre lang="HTML">   <ItemTemplate>...<input class="hideelement toggle" id="<%#Eval("ID") %>" type="checkbox" checked="checked"><label class="lblscanImg"  for="<%#Eval("ID") %> "> view scan</label>... </ItemTemplate>

I would like to link the label to input. the problem is the 'label's' id is the same for all the rows.?! when i select any label in the grid view, only the first element in the first row is affected. i inspected code behind and all the labels have the same id. I'm trying to make the id's unique so that when i select any random label in the grid, only within the selected labels row would its element change.
there is also no post back. so in conclusion: in what way can i change the id, that it would be unique for all rows.

I hope you understand. appreciate the help.

What I have tried:

i have tried to make the selection static, i have tried to but java script as the id, i no idea what to do.
