Thank your for the provided sample video and project.
I would like to provide some explanation about the different layout that RadScheduler offers in the different views and how they are arranged. On the left side of day view, week view and month view there is a ruler which is not available in timeline view:
It doesn't provide resizing functionality since the cells' size depends on the applied time scale and they are expected to be equal:
Additional information about the options that are available for managing the ruler is available in the following help article: https://docs.telerik.com/devtools/winforms/controls/scheduler/fundamentals/scheduler-ruler
The provided custom implementation allows you to resize the resources in RadScheduler. Each resource range represents a separate view element and you actually resize it.
If you want to have rows and columns resizing capabilities, I would suggest you to consider using RadGridView which provides this functionality out of the box:
RadScheduler is not intended to be used that way.
I hope this information helps. If you need any further assistance please don't hesitate to contact me.
