How to set radio button in init

[Former Member]

Hi people!

I'm sorry but i don't speak english.

I have the follow problem:

- When i check the radiobutton and save it, it works in database.

- But when i leave screen and after i come back to same screen the radio button showed is wrong:

I must define a node context? How to set it in the code to show the correct radiobutton?

Thank you!

Hi Anil Kumar!

Thank you for your reply!

Could you put here an example de code for this?

[anil_kumar259 · Accepted solution]

Are you using RadiobuttonGroupbyKey or RadiobuttonGroupbyIndex??

Do you want to set the default value in the Radiobutton??

[anil_kumar259 · Accepted solution]

If you are using the RadioGroupByKey you can declare the the default value like below in the init method

public void wdDoInit()

  {

    //@@begin wdDoInit()

      wdContext.currentContextElement().setAttribute("value");

    //@@end

  }

Im using like this:

I believe this method to set the context bellow:

It is using RadiobuttonGroupbyIndex!

But i dont know how i acess the method in the first print called "carregarCentroCusto".

I tryed to open it, but showed me a popupwindow and request login/password for DTR Console. I never used DTR Console. Usually the methods were in ComponentController or View...

Can you help me?!

It is using RadiobuttonGroupbyIndex!

assuming that the database holds the information for the last selected radio button, you need to make a call to the database in the init method to determine which radio button should be selected before the screen is rendered when the application is first launched

at the moment, I think you have chosen the first radio button to be selected  by default and hence why it is selected when you launch your application.
