    Hi to all!

     

    I have an issue with a RadComboBox during an insert.

     

    Context:

    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.

    Problem:

    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).

    Hello,

    The scenario seems rather complex and it will be difficult to guess what could be the root of the problem, especially since including a DefaultValue resolves the initial problem. Can you please elaborate what error is thrown after the insert and share the full stack trace of it? Additionally, can you please elaborate what is the data type of the "ToApp" field bound to the RadComboBox?

    On a side note, if you can prepare a sample, runnable project replicating the issue and attach it in a regular support ticket, we will be able to debug it locally.
