I will put the code on my blog later, you may add a iframe on the parent form. I give you the code which works for both 1:N and N:N relationship.
The 1:N relationship needs these parameters in the request URL: oId, oType, security, tabSet
The N:N relationship needs an extra parameter:
roleOrd in the request URL, which has been involved in the code.
function GetFrameSrc(tabSet)
{
if (crmForm.ObjectId != null)
{
var id = crmForm.ObjectId;
var type = crmForm.ObjectTypeCode;
var security = crmFormSubmit.crmFormSubmitSecurity.value;
var path = document.location.pathname.substring(0, document.location.pathname.search("edit.aspx")) + "areas.aspx?";
return (path + "oId=" + id + "&oType=" + type + "&security=" + security + "&tabSet=" + tabSet);
}
else
{
return "about:blank";
}
}
var navId = "nav_new_new_myentity_account";//replace the ID
if(document.getElementById(navId) != null)
{
var tmp = document.getElementById(navId).onclick.toString();
tmp = tmp.substring(tmp.indexOf("'")+1, tmp.indexOf(";"));
var loadArea = tmp.substring(0, tmp.indexOf("'"));
var roleOrd = (tmp.indexOf("roleOrd") == -1) ? -1 : tmp.substring( tmp.indexOf("roleOrd"), tmp.lastIndexOf("'")).replace("\\x3d", "=");
crmForm.all.IFRAME_view.src = (roleOrd == -1) ? GetFrameSrc(loadArea) : GetFrameSrc(loadArea) + "&" + roleOrd;
}
The child entities can only be added once the parent entity has a valid GUID, so the above code has handled it already.
To build up a editable grid, you have to build a custom aspx page to accomplish the function.
Jim Steger and Mike Snyder has an example of editable grid in their new book:
