Hi,

just being curious: In what situation are you, that you have to dynamically create UI-Elements and I guess respective Context as well? Couldn't you just create the input-field in design time, set it invisible and set it visible dynamically when pushing that button?

Hi Lukas,

Jus to clarify on this: There might be situations, we don't know how many fields the user wants to create at runtime.

Let say, the user is inserting product items and their validities, we are not sure how many product items he is going to insert.

To simplify this situation we can use a table UI with add button also.

Thanks & Regards,

Kiran.

Hi Kiran,

Yes, OK, that does make sense and justifies the effort in this case, I agree with you.

But in OP's case I think he only wants one field:

after execution while i will click on + button one input filed should be created automatically and while i will clicik on

Still, it does make sense to dynamically create them if there could be one up to X to keep the application slender.

Hi Lukas,

Yep. If it is one input field he can set it invisible and onClick of add button he can set it visible. But User can click that button again.! and one input field has to create..!! Ok we will leave this to him. It doesn't make sense discussing on this without knowing what excatly the requirement was.
