Create a graph and a report from same dataset in rdlc reports

I have created a winform data entry connected to .accdb as source The entry part is done, and i have given a button to open another which must contain the summary of the data in table & in graph format.

I have created the table successfully in "Report1.rdlc" and used it in my form2 using report viewer.

I have created another report"report2.rdlc" and when i used it in my form2 using report viewer the below error is coming:

A data source instance has not been supplied for the data source 'Dataset1'

and here is the code for form load event

namespace WindowsFormsApp1
{
    public partial class MS_Dies_Report : Form
    {
        public MS_Dies_Report()
        {
            InitializeComponent();
        }

        private void MS_Dies_Report_Load(object sender, EventArgs e)
        {
            // TODO: This line of code loads data into the 'TrialDataSet.MSdies' table. You can move, or remove it, as needed.
            this.MSdiesTableAdapter.Fill(this.TrialDataSet.MSdies);

            this.reportViewer1.RefreshReport();
            this.reportViewer2.RefreshReport();
        }
    }
}
