Updated August 2026 \u2014 Part 10 restored (user profile in the header + dropdown Name fix).<\/em><\/p>\n In this part we finish the Identity work from Part 9: show the logged-in user<\/strong> in the header, and provide links to profile<\/strong> and logout<\/strong>. Before that, we fix a small UX bug \u2014 Country (and similar) dropdowns that show IDs instead of names.<\/p>\n Previously:<\/p>\n We will cover:<\/p>\n 1. Show Name instead of Id in SelectLists<\/strong><\/p>\n On New Patient<\/strong>, the Country dropdown may list country IDs instead of country names. That happens when Step 1:<\/strong> Open Step 2:<\/strong> Change the third argument from Do the same in Edit if you pass a selected value:<\/p>\n Step 3:<\/strong> In Repeat for any other FK dropdowns (State, City, \u2026) that currently show IDs.<\/p>\n 2. Pass the current user into the layout<\/strong><\/p>\n Part 9 added Option A \u2013 inject Then, inside the header markup:<\/p>\n If your layout is not already async, change the top of Option B \u2013 ViewComponent Invoke with 3.
