I want to fixate the row header columns. I have given the row columns a fixed width. But I still can grab the columnheader splitter and resize the columns?
Forgot to mention: it is about the Scheduler. And I want to style columnheader_splitter as well.
The latest sandbox build (2019.2.3812) now supports rowHeaderColumnsResizable property which lets you disable the row header column resizing:
dp.rowHeaderColumnsResizable = true;
When the resizing is disabled, the splitter width will be set to 1px.
You can apply custom styles to the splitter by overriding the styles for :scheduler_default_columnheader_splitter class" (for the default theme). You can also generate a custom theme using the theme designer (https://themes.daypilot.org/) and manually adjust the output CSS file.
