[CLOSED] disabling rowexpander collapsible from code behind

[redi]

Hi,
How to disable rowexpander collapsible from code behind?

[Daniil]

Hi @redi,

If "collapsing" is disabled, then the expander rows cannot be collapsed - is that what you mean?

[redi]

Yes, because I want to add a condition when a parent row doesn't have any child, the collapsible button won't show.

There is no way to disable it from code behind, but you can set up a RowExpander's Renderer and return false from there for rows that you don't want to appear with a "+/- thing. Parameters passed to a Renderer should be good enough to determine you should false or not.
