Thanks for reply Alex,
I have many custom features besides multiline text so i have created custom
renderer for it.
I dont need wordwrap here and text is not multilines by wordwrap=true.
Actually I am concatenating 3 different values seperated by "\n" in
labelFunction thats why i have used textData.text =
gdeColumn.itemToLabel(value); in set data function.
I applied your changes by assuming textData.validateClient(true) is
misspelled and it is textData.validateSize(true) then cell is showing only
single line data. I didnt find validateClient() in property? please let me
know
in measure function in custom renderer, Do we always have to call
super.measure at last?
please let me know
