Disable specific row selection in GridField

@prakharg I don't think it's viable. Afaik, an alternate is to switch to Editable Grid, which I wouldn't recommend personally as it lacks sorting and pagination. Also, you may also think of adding a validation message in the paging grid which conveys to the user that the selection made is invalid.

Thanks you very much sikhivahans,
i will consult with the business for the options mentioned (Editable grid / Validation) and will take action accordingly.

instead of disabling the row in the Gridfield you can null out the gridSelection.selected in the saveInto if that certain condition is met.

Thanks Omere, I have opted for use of Grid layout instead Grid Field

How to null out the gridselection.selected in the saveInto? Can you send a code snippet?

It is possible to disable the rows based on the condition. First you need to identify the rows that needs to be disabled and have to form an array. For example, suppose you have 5 rows and the row 1 & 3 needs to be disabled because the data is not eligible then you need to form an array say {N,E,N,E,E} (Where N - Not Eligible & E - Eligible), and pass this array one by one in the rowlayout rule and put a condition on disabled parameter as : if index = N, true, False.

Hope this may help you.

Actually you can easily sort and page an editable grid with custom paging controls.
