Hi,

Looking for how to do this? I have a lookup field on one form... I want to get other data from the selected record in the lookup field to populate another field on the form.

I've found a million articles with the same stuff.. that shows how to get id, name, and type... but I want to get a different fields from those from the original record, in this case users entity.

This works to get id from new_user lookup field on form.

function GetUserDetails(executionContext) {
var formContext = executionContext.getFormContext();
var entityId = formContext.getAttribute("new_user").getValue()[0].id.slice(1,-1);

alert(entityId);

}

But can't use it to get fullname for example?

Doing this doesn't work:

formContext.getAttribute("new_user").getValue()[0].fullname;

Anyone help with missing piece?

Thanks,

Terry

Terry,

I'm glad that you resolved your issue. And just for your understanding - I'm not for the "giving the fish" I'm for the "teaching to fish" approach if you understand that.

marked this as the answer, but would've been nicer if there was some direct examples or something... but after trial and error I have it working. For others looking for this here's what I did:

function GetUserDetails(executionContext) {
var formContext = executionContext.getFormContext();
var entityId = formContext.getAttribute("new_user").getValue()[0].id.slice(1, -1);

if (entityId !== null) {

Xrm.WebApi.retrieveRecord("systemuser", entityId, "?$select=fullname").then(

function success(result) {
if (result !== null) {

//set text field
if (result.fullname !== null)
formContext.getAttribute("new_name").setValue(result.fullname);
}
},
function(error) {
alert(error.message);
}
);
}
}

Thanks,

Terry

Hello Terry,

You will need to use Xrm.WebApi for this purpose. Check this post - carldesouza.com/.../
