Gantt
#1

Hi All,

we have Gantt chart and that is having associated tasks. there when we double click on Task popup will appear.

in that popup we want user to modify only time and date not the Description

is there anyway that we can disable that textbox or prevent users to keying on the description textbox?

Hi,
Unfortunately I can’t provide you with a built-in solution for disabling this input with text, but can suggest a workaround to avoid text editing.
If user updates text, set again the option that was before opening lightbox and show message that text can’t be edited. Example code:
