I've got a text box on a sales order line custom field.
When the sales order is closed, I want this column to still be allowed edits.

Can't work out how to do it.
I've tried in the LineCustomFieldPlugin section, FormatCell.

Code: Select all

GridObject.LockColumn(false,"My ColName", Row);

Also have tried similar code in the LineDisplayed event of the form, and the sales order ReadEnd event.

None have worked. What's the trick?

v. 7.2.1. SR22.

LineDisplayed of the form will definitely do what you want - if you've tried that already and it's not working then your "My ColName" is probably wrong - hard to say for sure without a sample, but usually that's what trips most people up.

Use the manage grid function to see the key of the column - you'll see it's actually {Plugin Name}.{Custom field name} - to you might need to change "My ColName" to "My Plugin Name.My ColName".

your "My ColName" is probably wrong

Yep.
This is better

Code: Select all

String.Format("{0}.{1}", _plugin.Name, "My ColName")

Needed on LineDisplayed and the SalesOrderLineChanged events.

Are you saying that resolved your issue? Or were you just pointing out that your example was over-simplified and you already were using {Plugin Name}.{Column Name} ?

No need to do both - just LineDisplayed will suffice.

Yes. By having both the plugin name and the custom field name, that was what I was missing and resolved the issue.
