问题 I'm generating a 'select' element then populating it with options and inserting it into the DOM of my page. Everything's fine in FF, Chrome, Chromium etc. but in IE no options show in the drop-down list but highlights show under the cursor and when I click in the blank list the event handler gets triggered and processes correctly. Here's the relevant HTML area: <span id="spn_fyear" style="position:absolute; top:7px; left:200px; height:24px; cursor:pointer; color:#000000;" onclick="spn_fyear

问题 We are working with Trackable Entities on top of EF 4.0. In order to delete an Entity with all its dependent entities I'm writing a generic DeleteDependentEntities to be called from the Delete method in the EntityManager. (We don't, or don't want to, rely on a CASCADE DELETE to be set on the relations in our database.) The DeleteDependentEntities scans recursevly all Children of the subjected entitySet. In order to keep it generic, so that it can be used for all entities throughout the
