Interesting, it would be useful to know if a field is written.

just check the length of the textbox text property…

i tried to use that, but when i use “when enter pressed” to select focus of next textbox, never it goes where i want

posted already…

which means, your issue is an Extra Components Extension issue and is not related to the textbox extension…
i.e. your contribution in this thread we can consider as off topic…

sorry, i understood you ask me that

@Taifun great extension. thanks
Can we highlight text using different colors ? if no then is it possible to do it somehow ?

@Hitesh I will check, if this will be possible…


the new methods SetBackgroundImage, GetHighlightColor and SetHighlightColor are now available in the textbox extension …



you’re great man

thanks a lot. i love it.

i have another wish…since i’m using the dialog ext, i cannot use the extra component…so i miss “after enter pressed” event…:smiley:

I now added an EnterPressed event in Version 5 of the Textbox extension
Additionally you can set the icon of the Enter button in the soft keyboard. Possible values for icon: DONE, GO, NEXT, PREVIOUS, SEARCH, SEND

Thank you @Boban_Stojmenovic for being the sponsor of version 5!
