I would like to not only retrieve (and display) child data only when a parent row is clicked on a hierarchical grid. We're using jQuery in our application. We have a considerable amount of child data for each master in our hierarchy so we only want to retrieve when necessary from a parent. I was thinking of using the "rowExpanding" event. From there somehow get the "key" from the parent record, then using an ajax call, make a call to the server to retrieve json data and set the data source of that particular parent to the child data. I've done things in the past with _dataSoure (something like that) but only in igGrid. I thought I could get igGrid methods via the igHierarchical object. I was looking for something like "getRecordById" where I can find out what parent was clicked. the "load on demand" articles didn't show how I can do this fully in jquery.
I'm actively trying to get my new employer to purchase infragistics and today we have handlebars and constantly do a completely new search every time a user clicks a page. I have about 5 years experience in your UI product but have been away for some time and haven't used the hierarchical grid much in the past. I tell them how great your products are and all of this searching, retrieving, etc. can easily be done with your products. I need to do a quick proof of concept to convince my boss to upgrade our license. The company I work for has 2017.2 but no one uses it. I want to show them this is worthwhile and possibly upgrade all together. But I need to get this sample working.
