Trigger to update a checkbox in a relatedlist
Hello,
I have a requirement to write a trigger to update the checkbox on the relatedlist of an object.
Scenario
There are 2 objects here
1.master__c
2. child__c
There is a custom field on the child__c called "check__c". so if there are two child__c records on a master__c record. only one child__c record can be updated with the check__c as "true" at any given point of time, so, if we try to update the other child record as true, the check box on the first record should get unchecked.
Any help will be appreciated.
Thanks,
vamshi

if(d.ChechBox__c==true) {
dm = [Select id,name from Child__c where ChechBox__c=true];
}
for(Child__c c1:childList) {
if(c1.id!=c.id) {
c1.ChechBox__c=false;
