title: A data source instance has not been supplied for the data source 'Request'
body: <p>I'm getting an error on my reportviewer which I am not sure how to correct this.... 
  The error that I am gettings is : " A data source instance has not been supplied for the data source 'Request'."
  I have tried searching for this, but can't find anything that I can see that is wrong, can somebody please point me in the right direction? This is how my reportvierer looks like:</p>
  
  <pre><code>    &lt;rsweb:ReportViewer ID="rptViewer" runat="server" Height="654px" 
  Width="924px" Font-Names="Verdana" Font-Size="8pt" 
      InteractiveDeviceInfos="(Collection)" WaitMessageFont-Names="Verdana" 
      WaitMessageFont-Size="14pt"&gt;
      &lt;LocalReport ReportPath="Report.rdlc"&gt;
      &lt;/LocalReport&gt;
  </code></pre>
  
  <p></p>
  
  <p>This is the code I use for the reportviewer:</p>
  
  <pre><code>    SqlConnection conn;
  
  protected void Page_Load(object sender, EventArgs e)
  {
      conn = new SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString);
  
      conn.Open();
  
      if (!Page.IsPostBack)
      {
          runRptViewer();
      } 
  
  }
      private DataTable getData()
  {
      DataSet dss = new DataSet();
      string sql = "";
      sql = "SELECT CC_Request.Company, CC_Request.Attention, CC_Request.Telephone, CC_Request.Email, CC_Items.Model, CC_Items.SerialNo, CC_ItemsRequested.Item, CC_ItemsRequested.Quantity, CC_ItemsRequested.Price, CC_ItemsRequested.ModelID, CC_Items.RequestID FROM CC_Request INNER JOIN CC_Items ON CC_Request.RequestID = CC_Items.RequestID INNER JOIN CC_ItemsRequested ON CC_Items.ModelID = CC_ItemsRequested.ModelID WHERE (CC_Request.Company = 'Alpha') AND (CC_ItemsRequested.ModelID = 20) AND (CC_Items.RequestID = 1)";
      SqlDataAdapter da = new SqlDataAdapter(sql, conn);
      da.Fill(dss);
      DataTable dt = dss.Tables[0];
      return dt;
  }
  
  private void runRptViewer()
  {
      this.rptViewer.Reset();
      this.rptViewer.LocalReport.ReportPath = Server.MapPath("Reports\\Report.rdlc");
      ReportDataSource rds = new ReportDataSource("dsNewDataSet_Table", getData());
      this.rptViewer.LocalReport.DataSources.Clear();
      this.rptViewer.LocalReport.DataSources.Add(rds);
      this.rptViewer.DataBind();
      this.rptViewer.LocalReport.Refresh();
  }
  </code></pre>
  
  <p>Any help will be greatly appreciated.</p>
  
  <p>EDIT-----------------------</p>
  
  <p>this does not work either:</p>
  
  <pre><code>    private DataTable getData()
  {
      DataTable dtable = new DataTable();
      dtable.TableName = "dtNewDataSet_Table";
      string sql = "";
      sql = "SELECT CC_Request.Company, CC_Request.Attention, CC_Request.Telephone, CC_Request.Email, CC_Items.Model, CC_Items.SerialNo, CC_ItemsRequested.Item, CC_ItemsRequested.Quantity, CC_ItemsRequested.Price, CC_ItemsRequested.ModelID, CC_Items.RequestID FROM CC_Request INNER JOIN CC_Items ON CC_Request.RequestID = CC_Items.RequestID INNER JOIN CC_ItemsRequested ON CC_Items.ModelID = CC_ItemsRequested.ModelID WHERE (CC_Request.Company = 'Alpha') AND (CC_ItemsRequested.ModelID = 20) AND (CC_Items.RequestID = 1)";
      SqlDataAdapter da = new SqlDataAdapter(sql, conn);
      da.Fill(dtable);
      DataTable dt = dtable;
      return dt;
  }
  </code></pre>
