Field validation

[Wicket]

Hi All,

 

What is the best way to validate fields on a modal form?

 

I need to check that the field is not empty before closing the form - usually I would do this on the button OK click, setting the modalresult = mrnone, then check the fields are <> '', then call modalresult = mrOK.

 

I cant use this technique in unigui due to the multi-threaded nature.

 

So, my question is how can i not close the form if I have a certain required field that is empty?

 

Any elegant way to achieve this?

 

Thanks,

 

Dan

Hi,

 

It is quite simple.

 

In OnClose event check your fields and set CloseAction to caNone if form should not be closed.

Thanks Farshad - I'm always over complicating things!

THis doesn't work for me.

I set the Action:=caNone;

And the form STILL CLOSES.

 

Do you have an example demo to show how to do it properly?

BTW: I am using      formname.ShowModal;    to display the form.

Thanks
