Question

How to configure custom validations, enable a readonly filed while editing in Grid plus component?

I am building POC using a grid plus component, i need help solving below two issues

1. when i try to add custom validations like preparerDueDate<RevieweDueDate it does not validate properly. Even if one row has the validation to true, the message shows on all row for that field.

2. I have a column that cannot be edited when once added, when creating a new record i need the column to be editable. how can i achieve this functionality?

Thanks in Advance.

Hi [mention:0819bff85cde4d19a27958b01984d3e9:e9ed411860ed4f2ba0265705b8793d05] ,

I'm not sure this would work or not on Grid Plus 
but instead of using  this as validation message " fv!row.preparerDueDate < fv!row.reviewerDueDate "
we can utilise using the index when we are storing the values or implementations 
 local!records[fv!index].preparerDueDate 


For the 2nd point, if existing records already have a primary key:

readOnly: not(isnull(fv!row.id))

Meaning:

  • New row → id = null → Editable
  • Existing row → id has value → Read Only

This is probably the simplest solution since IDs are assigned only after creation.
