Hi Vaibhav,
Thanks for using Syncfusion product.
We have analyzed. We replicated the scenario in our sample, but we are not able to reproduce the issue reported.
Please find the below code snippet to change the type of the series in button click.
[CS]
private void button1_Click(object sender, EventArgs e)
{
this.chartControl1.Series[0].Type = ChartSeriesType.Spline; // series type is changed to spline
}
We have also made a sample to illustrate this. Find it from the below location.

If you still face any concern, kindly modify the sample and revert back to us with replication procedure.
This will be helpful for us to fix the issue sooner.
Please let us know if you have any concern.
Thanks,
Jayavigneshwaran
