Refresh or Initialize a Block
Question
Aggregate
Best Practices

I can't share my OML. So, I'll try my best to explain my issue.

Consider there is a block "A", It has 2 more blocks in it Block B and C respectively.

> Block B contains a form.
> Block C contains a table to display.

My expectation is, whenever I submit the form in Block B, the whole "Block C" must be initialized or refreshed.

Hi @Nandhakumar S 

Steps :

  1. In Block B create a local Boolean var eg Is Submit. On click of submit set its value to True. Create an event and pass this IsSubmit to value. ( event handler create in Block A as Block B/Block C are called in Block A). Hold the value in local var in Block A.
  2. In Block C, have one input parameter and bind with local var created in block A. 
  3. In Block C, create OnParameterChange action. Since input value changes your this action will be triggerd. You can refresh (or do your required logic) on conditional basis.

Hope this helps!

 In block C there is no input fields. So, how will you use the on parameters change?

It only contains a table where it displays data.

We will pass the Id or any value which will trigger the on-parameter change of your block C.

Hello

Adding a sample for you to achieve this,
You need to pass some value to the block in which you want to display the data 
And once the value is changed the on parameter will be triggered and yu can refresh your screen
