            OleDbConnection con=new OleDbConnection("Provider=Microsoft.jet.oledb.4.0; data source="+Application.StartupPath+@"\DataInfo1.mdb");           
            con.Open();
           OleDbDataAdapter da=new OleDbDataAdapter(@"SELECT ct.custID, c.custName, c.custAdd, ct.custTranDate, ct.custTranType, ct.custPaidAmt, ct.custDueAmt, c.custArea FROM custTransaction AS ct LEFT JOIN custDetails AS c ON ct.custID = c.custID WHERE ct.custID='CUST-000002' and ct.custTranDate BETWEEN #2/28/13# AND #3/1/13#;",con);
           DataSet ds = new DataSet();

           da.Fill(dt);           
           ds1 = dt; //Error is here
//           MessageBox.Show(ds1.Tables[0].Rows.Count.ToString());
           CrystalReport2 cr = new CrystalReport2();

In your code you write DataSet1(). What is it??

I added DataSet1 from Project - Add New Item Dialogue Box and select DataSet from the List(default name is DataSet1.xsd)...
Select DataSet1.xsd from Solution Explorer and right click . Select datatable from the menu then Right click the datatable and select Add-Column . that's the way I create DataSet1 and his fields..

A DataTable and a DataSet are different types, you cannot use an expression such as you have coded. Go to MSDN and read the documentation for each class.

Sir, I know that's different types,
but is there any way to assign the all tables with rows from Data.DataSet to the DataSet1??

A quick check of the documentation reveals the answer.
