Hi Guys.

I am building a project that draw a chart with real time using Microsoft Control Charts. Data source of chart changes every a few seconds to reload data. but i have got a trouble with it. The error is '{"Cross-thread operation not valid: Control...'

I use thread job to start thread every time when checking thread is complete.

private void gLoads()
  {

   jHOSEIDX = new ThreadStart(LoadChart);
   tHOSEIDX = new Thread(jHOSEIDX);
   GTimer.Interval = 10000; // 10 seconds 
   GTimer.Tick += new EventHandler(Otherwise);
   GTimer.Enabled = true;
  }

Here is otherwise method.

private void Otherwise(object sender, EventArgs e)
{
 if (!(tHOSEIDX.ThreadState.ToString().CompareTo("Running") == 0))
 {
  jHOSEIDX = new ThreadStart(LoadChart);
  tHOSEIDX = new Thread(jHOSEIDX);
  tHOSEIDX.Start();

 }
}

Loadchart is a method reload data and adjust properties of chart.

private void LoadChart()
  {

    VnIndexChart.Titles[0].Text = "VN-Index";
   
   string fileNameString = AppDomain.CurrentDomain.BaseDirectory + @"\Data\Data.mdb";

   string myConnectionString = "PROVIDER=Microsoft.Jet.OLEDB.4.0;Data Source=" + fileNameString;

   string mySelectQuery = "SELECT TGian,Data.Ngay, Data.ChiSoHTai, Data.ChiSoGLap,Data.KLDuMua FROM Data Order By 1; ";
   OleDbConnection myConnection = new OleDbConnection(myConnectionString);
   OleDbCommand myCommand = new OleDbCommand(mySelectQuery, myConnection);
   myConnection.Open();
   VnIndexChart.DataSource = myCommand.ExecuteReader(CommandBehavior.CloseConnection);
   VnIndexChart.Series["VN-Index"].XValueMember = "TGian";
   VnIndexChart.Series["VN-Index"].YValueMembers = "ChiSoHTai";
   VnIndexChart.Series["VN-Index"].XValueType = ChartValueType.Time;

   VnIndexChart.Series["VN-IDX.ESTIMATE"].XValueMember = "TGian";
   VnIndexChart.Series["VN-IDX.ESTIMATE"].XValueType = ChartValueType.Time;
   VnIndexChart.Series["VN-IDX.ESTIMATE"].YValueMembers = "ChiSoGLap";

   VnIndexChart.Series["Qlity"].XValueMember = "TGian";
   VnIndexChart.Series["Qlity"].YAxisType = AxisType.Secondary;
   VnIndexChart.Series["Qlity"].XValueType = ChartValueType.Time;
   VnIndexChart.Series["Qlity"].YValueMembers = "KLDuMua";
   VnIndexChart.DataBind();
   UpdateChartSettings();


  }
