If you want to have the same size for all the webresources you show, then it's easy you can adjust the rowspan attribute
In our case, every webresources has a different size... So the size have to be dynamic according to the IFrame content.
I didn't find any supported way to do that.
Here is what I ended to do:
function onload(e) {
//...
fc.ui.controls.get("IFRAME_ModalDialog").setSrc(Xrm.Utility.getGlobalContext().getClientUrl() "/webresources/" webresource "?data=" data);
$("#IFRAME_ModalDialog").ready(function () {
setTimeout(function(){ resize();}, 300);
});
}
function resize(){
var webresourceHeight = window.top.$("div[data-id='PopupDialog']").find("div[role='presentation']").first().height();
window.top.$("#id-473a54c3-4989-4408-9b78-181a0b90d162-1-IFRAME_ModalDialog-webResourceLabelControlWrapper").height(webresourceHeight-35);
}
The guid that is in the id part correspond to the FormId
I spent lot of time on that and didn't find any better solution..
