RadChart - How to change item style by triggering CreateItemStyleDelegate

[De]

I have the need to trigger RadChart.CreateItemStyleDelegate in code.  Basically I have some logics in CreateItemStyleDelegate to create different styles based on input data.  On the initial startup, all UI controls  are created and data bound are fine.  After that if the user change one of the important attribute on ViewModel, I need to tell the control to re-create styles for all items (throught CreateItemStyleDelegate).  Anyone knows what would trigger CreateItemStyleDelegate?

Notes that I am trying to avoid to recreate the entire control.

Thanks,

Hello De,

A possible way to achieve the desired is to call Rebind(), but this will recreate the whole control. That is why I suggest you to use the exposed Appearance API. Please let me know if this is an appropriate solution for your case.

Hi ajit,

Unfortunately, the CustomDelegate functionality is not supported for 3D series.

All the best,

Hello Telerik Team,

We have similar use-case. I want to be able to change the background color of my Chart bars each time I get updated values for the source properties. We don't want to rebind each time. What do you mean by  "That is why I suggest you to use the exposed Appearance API."

Hi Kumar,

Here is list of all available options for styling RadChart:

• using the exposed appearance API, which means setting Appearance.Stroke, Appearance.Fill to the series definition;
• using custom palette (which as I understand is not appropriate for your scenario)
• using custom item style

I hope this helps.
