Silverlight RIA Service using ADO.NET Entity Data Model: Part II

Hello, I am new with silverlight. Would like to ask if you have implemented a text box search where in the field type is of date. Also, can it be done using related field such a customer table where there is a fields name cust_supplier_idno which is related to the supplier table's supplier_idno. I have been looking for such a solution and having a hard time looking for one. Most of the solutions are in MVVM and i wondering if it could be implemented using EF an RIA Services. Thanks in advance guys. almond

I have an iissue that is caused after update a model from the database. Here are the sequence of events. 1) Open the *.edmx file (e.g. Model1.edmx) from the Web project 2) Right-Click and slect “Update Model from the Database” 3) Follow the wizard and updated the changes I’ve made to the database (for example , adding a new column) 4)At this point I see the tables my Model1.edmx are successfully updated (I could see the extra column I’ve added) Also, I can retrieve (read) data and display it on my DataGrid 5) BUT, could not update, delete or add records back to the database. Please note that before I have execute the “Update Model from the Database” (#2), I was able to do update , delete and remove.

Thanks Raj, I cannot find the attached project mate. Has it been uploaded? Thanks Mick
