i making new datagridview cells can edited. have cellvalidating event handler, in set errortext of row , cell, no text or icon showing anywhere in window.
i have looked , followed many other issues this, nobody else's solution has worked me yet
- made sure showcellerrors & showrowerrors = true
- set dgv.rowtemplate.height > 19
- made sure dgv.autosizerowsmode not set anything
- set showtooltips = false
- even tried not doing
e.cancel = truein cellvalidating handler
so else there might block row and/or cell errortext appearing on screen?
