c# - Event on dynamically created checkbox asp.net -

i started programming asp.net, have table checkboxes.

the problem is, can't create static tables, because action linked parameters. anyway.. when click on first checkbox want invert other checkboxes in table. how can catch event?

you can try code

 list<checkbox> lstchckbox;      protected void page_load(object sender, eventargs e)     {         // can create controls programaticaly or html page, doesnt important         //only should know controls id , controls share same checked event         checkbox chc1 = new checkbox();         chc1.checkedchanged += new eventhandler(chck_checkedchanged);         checkbox chc2 = new checkbox();         chc2.checkedchanged += new eventhandler(chck_checkedchanged);         checkbox chc3 = new checkbox();         chc3.checkedchanged += new eventhandler(chck_checkedchanged);           // now, can create list event fired, can catch controls checked or not          lstchckbox = new list<checkbox>();         lstchckbox.add(chc1);         lstchckbox.add(chc2);         lstchckbox.add(chc3);     }      void chck_checkedchanged(object sender, eventargs e)     {         checkbox checkbox = (sender checkbox);         foreach (checkbox item in lstchckbox)         {             if (item != checkbox)             {                 item.checkedchanged -= new eventhandler(chck_checkedchanged);                 item.checked = !checkbox.checked;                 item.checkedchanged += new eventhandler(chck_checkedchanged);             }         }     }
