Add onClick functionality in onBeforeRowHeaderRender or onBeforeRowHeaderDomAdd

This seems to be a problem of some of the older releases. The latest version (2025.2.6442) should work fine with args.target = "Text";.

Could you please give it a try? Please let me know if the problem persists.

Thanks Dan. It’s better than before however in the UI, row header width and height does not auto adjust based on content length. Below is the image.

We have rowHeaderWidth and rowMinHeight property to use, however can we achieve this without explicitly updating the width and height similar like in onBeforeRowHeaderRender? Thanks

The row height is calculated from eventHeight and the maximum number of overlapping events + it takes into account adjustments like rowMinHeight. So it doesn’t depend on the row header content.

There was a problem with automatic adjustment of the row header width when using custom JSX - React postpones the rendering and the content wasn’t available when the width was calculated.

Anyway - in the latest sandbox build (2025.2.6453) the width calculation should work fine with JSX in the row headers as well.

Please let me know if there is any problem.

We updated to the version 2025.2.6458. The height is working however the width is not working and it works only upon using rowHeaderWidth.

The React Scheduler: Rendering JSX Components in Row Headers tutorial now uses the latest release and the default rowHeaderWidth is reduced to 20 to test the row header width auto-fit.

It seems to work fine and the row header width is extended as expected. Could you please give it a try to see if you experience the problem in this project?
