Hi to all!
I have an issue with a RadComboBox during an insert.
I've made an ASP.Net app for my company to visualize dependencies between our apps by using a RadGrid for raw data and D3.JS for graphic visualization. The logic is easy: FromApp (id) is link to ToApp (id) and you have a comment field too. To do a new insertion I use the "Add new record" button from the grid, in the EditTemplate I've put one FromAppRadComboBox where you can select one app, a ToAppRadComboBox with checkboxes where you can select all the apps link to the one selected befor and a Textbox for comments. For having a record per link, I've made a CustomInsertion function called during the OnInsertCommand of the grid.
Regardless the amount of app I check in the ToAppRCB, it will always inserts the first item in addition to the others. I manage to fix this by using a default item, but once the insertion is done, when the app want to refresh then display the grid, it breaks, because of a convertion problem (maybe because of Entity Framework).
