Yes 2nd grid depends on 1st grid's result
Like if I choose the suburb(as shown in above attached picture) it will fetch the data from DB for relevant suburb and display that in next select box.
Any idea or different approach?

Hello Tooba,

Could you please detail what logic you want to implement in your application and what is the issue you have

Hi,

My Task:

I have 2 grids on my screen that has following fields.
Grid 1: State select box
Grid 2: Suburb select box, text box and a Submit button
If user selects the State- California then the service has to fetch the data in next select box. that is all the suburbs that are in California.

Then user fill other fields and submit the form

Issue:

When the screen is loaded the screen only shows grid 1
As the result if select box 2 in grid 2 depends on the result from service and service is called when User selects a value from State select box.

My Logic:
State Select Box - On value change - Invoke Service

I need to show the complete form on page load not just grid 1. How can I show complete screen?
Feel free to ask for more clarification

Thanks,
Tooba

On page show you can invoke service and populate suburbs select with default values, Alaska suburbs for example.

Regards.

Will try that!!
Thanks anyway!
