Hello Experts!
Hope u all doing fine.
I am here with another problem.
I have a master-detail form showing multiple records (tabular) in data-block. Now my problem is, based on certain column's value of a particular item in a particular row on the data-block to ENABLE/DISABLE during run-time .
For example, in a detail-block of 5 rows, if 3rd row's 'detail-block.item1' is equal to lets say, "X", then 'detail-block.item2' of that particular row ONLY must be 'disabled'. otherwise, it must 'enable' the 'detail-block.item2' of that particular item in that particular row on the data-block.
Even when, I query the form, it must enable/disable that particular item of that particular row from the data-block based on item1's value.
please some body help me to solve this.
thank you very much in advance to one and all.

You can't set the enabled property of any item on a per row basis.
2 Choices:
1) Have code in the when-button-pressed that raises an error if the button should be disabled.
2) Make the button part of a seperate data block and have it appear on the canvas once, rather than once per row. Then you can enable/disable it using when-new-record-instance and when-validate-item.
