Custom images for track bar buttons

[Toby]

Hi, I was wondering how I could specify my own images (from my project resource file) for the buttons in a vertical track bar. Is this possible? if so how?

I probably need to do this at run-time due as the user is able to change themes which I suspect will cause things to go wrong.

 

Regards

Toby

You'll be pleased to know I read the help and found the solution at https://docs.telerik.com/devtools/winforms/controls/track-and-status-controls/trackbar/customizing-appearance/accessing-and-customizing-element

But on a similar theme is it possible to set the colour of the indicator bar at run time ?

Hello, Toby,

If I understand you correctly, you would like to change the color of the indicator that shows the progress in RadTrackBar. In order to achieve this, please refer to the following code snippet:

TrackBarIndicatorElement indicator = this.radTrackBar1.TrackBarElement.BodyElement.IndicatorContainerElement.Children[0] as TrackBarIndicatorElement;
indicator.RangeElement.BackColor = Color.Lime;
indicator.RangeElement.GradientStyle = GradientStyles.Solid;

I hope this helps. Should you have other questions please let me know.

Regards,
Nadya
