Display Child Records in Table
I have a custom object Parent__c and child records Child__c. I want to show fields from the child record that corresponds with its parent record. But, I want the titles for each child column to appear only at the top of the Visualforce table. Like:
Parent Field TItle Child Field 1 Title Child Field 2 Title Child Field 3 TItle
P1.Value P1.C1.Value P1.C1.Value P1.C1.Value
P1.C2.Value P1.C2.Value P1.C2.Value
P2.Value P2.C1.Value P2.C1.Value P2.C1.Value
P2.C2.Value P2.C2.Value P2.C2.Value
P2.C3.Value P2.C3.Value P2.C3.Value
etc.
Does anyone know how to do this?
Thanks!
Hey,
You should be able to do that with nested pageblocktables.
<apex:pageblocktable value = "{!myParentList}" item = "parent">
<apex:column value = {!parent.name}"/>
<apex:column>
<apex:pageblocktable value = "{!parent.child__r}" item = "child">
..and so on. You may have to play with it to show it exactly how you want, but the general idea should get you there.
Thanks for your help, but I must be doing something wrong. When I first implemented as you suggested, I got an error saying that "item" is an invalid field for pageblocktable. I presumed you meant "var" and changed accordingly. Then I ran into compile errors saying that pageblocktable must be contained within a pageblock section. I added that and got an error when the page loaded saying that pageblocktable must be contained within a pageblocksection. Below is code. Perhaps I'm not implementing as you suggested?
<apex:page controller="dbPracticeChangesController">
<apex:pageblocksection >
<apex:pageblocktable value="{!ChangeList}" var="parent">
<apex:column value="{!parent.name}"/>
<apex:pageblocksection>
<apex:pageblocktable value="{!parent.dbPracticeChanges__r}" var="child">
</apex:pageblocktable>
</apex:pageblocksection>
</apex:pageblocktable>
</apex:pageblocksection>
</apex:page>
