Hi friends.

I have one big doubt. I have "Customer Master". Customer Master contain 22 fields. I have Db Contain Multiple tables for Customer Master. If I connect my Db with Vb express it shows each view for each table. so i tried to bring all fields in single view and tried to insert the data into multiple tables. For that I used "Code First Approach " i followed the method same as like which is mentioned in the below link. Its working Fine.

Inserting Data into Multiple Tables using Code First Approach and ViewModel[^]

Now my question is I Finished the insert process using Code first approach.. Now " how to do UPDATE process using this approach.. Because i did only the insertion process . still i need to do Update , Details, Delete.. How to do that?

Thanks..
