Description marc meumann 2015-03-03 05:51:13 EST

Making changes to a Barseries' fill gradient (eg. Direction) isn't showing up at designtime when making those changes with the editor.

Workaround:
Disabling cache resolves the issue.
ie. Steema.TeeChart.Utils.UseCaches = false;

The following code works as expected with UseCaches either true or false:

    Bar series = new Bar();

    private void InitializeChart()
    {
      tChart1.Aspect.View3D = false;
      tChart1.Series.Add(series);
      series.FillSampleValues();

      series.Gradient.Visible = true;
      //Utils.UseCaches = false;
      EditorUtils.FillEnum(comboBox1, typeof(LinearGradientMode));
    }

    private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
    {
      series.Gradient.Direction = (LinearGradientMode)comboBox1.SelectedItem;
    }

Also, using the Chart Editor at runtime means works as expected when changing the Gradient Direction. The Chart Editor at designtime seems to be the only area in which this issue occurs.

Last comment inaccurate, code snippet can reproduce issue with Utils.Caches = true.
