Hi

Then I added a button and if I click on the button I'd like to change X Axis Grid color to Yellow.
But it doesn't work.
Could you help me, please?

Hi Syrthey,
It looks like there is a small issue with the scale configurator - it does not mark the scale for update so you need to force the update:
This code worked Ok:
private void button1_Click(object sender, EventArgs e)
{
nChartControl1.Charts[0].Axis(StandardAxis.PrimaryX).ScaleConfigurator.MajorGridStyle.LineStyle.Color = Color.Yellow;
nChartControl1.Charts[0].Axis(StandardAxis.PrimaryX).InvalidateScale();
nChartControl1.Refresh();
}
We'll be looking in detail in the problem and the fix will appear in the next major release of the control. We hope this helps - let us know if you have any questions or meet any problems.
