"TelerikDemo.User does not contain a property with the name Address" problem

[t800t8]

I have a master/detail RadGrid. I open the form to insert new record to Master table, then open the form to edit a record in Detail table. When I click Cancel on the form to create new, I have an HttpExpcetion "TelerikDemo.User does not contain a property with the name Address". Are there somethings I miss? Thank you.

Here is my markup:

Anyone can help? Thanks

The problem here is when I click Cancel to close the edit form for master row, RadGrid will re-fill data for the edit form for detail row, but at that time the selected item is the MASTER one, not the DETAIL one. How can I re-fill the edit from for detail row without any problems?

Hello,

I have examined the code you have pasted and I have noticed that you are incorrectly binding the details table inside DetailTableDataBind. You should assign the datasouce to the currently binded tableView. Thus your code should look similar to the following:

        GridDataItem parent = e.DetailTableView.ParentItem;
        int userId = Convert.ToInt32(parent.GetDataKeyValue("Id"));
        e.DetailTableView.DataSource = Contact.GetAllContactsForUser(userId);

Please give it a try and let us know if this helps.
