We have a JS button in Classic which perform some checks and open the /lead/leadconvert.jsp? page with some fields prepopulated. Now we are migrating to Lightning, so for replacing the button we created quick action and redirecting the user to /lead/leadconvert.jsp?. But it is navigating to the classic page . Are there any events like force;createRecord which we can use for opening the Lead convert standard modal window.

  • Why not use standard lead convert button for the lead in lightning? – Pranay Jaiswal May 8 '18 at 14:20
  • We are checking for certain conditions. For example if field A is null, then we are throwing error message and not opening lead convert page . So we need quick actions or js buttons – Ravi Narayanan May 8 '18 at 14:22
  • You have to create a custom quickaction and embeded a lightning compoment in it. that lightning component will do all validations and then prepopulate itself. You have to write lead convert logic in Apex as far my knowledge is concerned. – Pranay Jaiswal May 8 '18 at 14:27
  • @Ravi, did you ever find a solution for this? – Dedo Aug 13 '19 at 4:45

Instead of going at it the way you've done, consider blocking it with a trigger:

trigger CheckValidLeadConvert on Lead (after update) {
  for(Integer index = 0, size = Trigger.new.size(); index < size; index++) {
    if(!Trigger.old[index].IsConverted && Trigger.new[index].IsConverted) {
      // Check for whatever conditions you like
      Trigger.new[index].addError('You cannot convert this lead because blah blah blah...');

You may also be able to use validation rules as well, since they now also run on lead conversion. I realize that this is slightly less ideal than aborting early, but using a trigger will prevent a lead from being converted incorrectly in any means, including Apex Code, Visualforce, Lightning, API, and Classic.
