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 for an individual row of an item.
Best you can do is set insert and update allowed to false and change the visual attribute to make it look like it's disabled.
Use set_item_instance_property to do this.

Put the necessary code in the when-validate-item trigger on item1 and post-query on the block.

actually I want to DISABLE a push button of particular row, if 'Status' (an item on form) of that particular row shows "Returned".
If the "Status" shows "Using" the push button should be ENABLE.

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.

If this has not been resolved, I think 6i still includes the set_item_instance property. I'm pretty sure that's what you're looking for

Yes it's in 6i, and later versions.
But you can't use it to set the enabled property, hence my earlier comments.
