I create chart as follows:

            var barModel = new BarSeries
            {
                ValueMember = "Model",
                CategoryMember = "N"
            };
            radChartViewGss.Series.Add(_barModel);
            var barWellModel = new BarSeries
            {
                ValueMember = "WellModel",
                CategoryMember = "N"
            };
            radChartViewGss.Series.Add(barWellModel);

...creating and filling a table (DataTable gssTable)

            radChartViewGss.DataSource = gssTable;

... and show table
            radGridViewGss.DataSource = gssTable;

Everything works great.

Then I want to change the data:
           radChartViewGss.DataSource = null;

           radGridViewGss.DataSource = null;

            gssTable.BeginLoadData();
            gssTable.Rows.Clear();

... filling a table (gssTable)

            gssTable.EndLoadData();
            gssTable.AcceptChanges();

During the data modification process, the radGridView is not updated, but radChartView constantly tries to update itself. As a result, everything works very slowly.

Why two similar component behave differently when data source disconnected?

I know how programmatically I can disable this behavior of the chart. But this should be done automatically!!! If there is no data source, the chart is not drawn
