    Hi all, please help me with this: How to View the "INNER JOIN" in C# for example Customer(CustomerID, CustomerName) Order(OrderID, CustomerID, OrderDate, OrderAmount) A list of customer who made order of month could be easy collected by SQL query as below:

    select C.CustomerID, C.CustomerName, O.OrderAmount from Customer C join on Order O (C.CustomerID = O.Customer ID) where Month(O.OrderDate) = month(getdate())

    who can I do it in Dataset? for display purpose

    Dataset dsCustomerOrder = new Dataset("CustomerOrder"); DataTable dtCustomer = ....; DataTable dtOrder = ...; dsCustomerOrder.Tables.Add(dtCustomer); dsCustomerOrder.Tables.Add(dtOrder); DataRelation drCustomerOrder = new DataRelation("R_CustomerOrder", dtCustomer.Columns["CustomerID"], dtOrder.Columns["CustomerID"]; ............... I want to bind it to DataGird with following columns: CustomerID, CustomerName, CustomerOrder

    Thank you
