[Solved] Event triggers for text control?

[owlbrudder]

On a form I can add controls and they all have associated events which can trigger macros. The only type of control not having events seem to be those associated with a table - at least, the form has an associated table it can scroll through and controls on the form are tied to fields in the table. Is this right, or am I misunderstanding something?

To explain further: I would like to raise a visual flag if a certain value appears in a control as the user scrolls through the records and I was going to use control events for this, but there don't seem to be any events.

Any help would be appreciated.

A table control on a form is a bundle of controls. Each column represents one control of any type. See column properties. There is no formatting for individual rows nor columns and no macro can add this missing feature. The best you can get without macros is a formatted field with conditional number format. Formatted fields are very much like numeric spreadsheet cells with the same number format attributes, e.g. red font color for negative numbers: #,##0.00;[RED]-#,##0.00
Reports can do more if you use the report builder extension or if you use Calc for database reports.

Thanks for the quick response. I have found I can manully add a text control (for example) and set its datasource as a field of the form's recordset and this control retains all its events, so I have a work-around for when I need it.

You can also hide and unhide form controls.

Hello,
find attached another approach, using a query to find the event and display the information in a textcontrol having the same backgroundcolor as the form itself. An information will appear, if the NUMBER is less than -50.

hide and unhide form controls.

Good - I was counting on that for when I use a manually-created data control. I would have the standard control invisible and my control over the top of it. Thanks for the suggestion.

Thanks - that is very kind of you. I will study your technique as it sounds like a simplification of what I was planning to do.

F3K Total, solving the problem through SQL is a neat alternative. Now I can use either method depending on the circumstances. Thank you again.

Hello,
find attached a combination of Villeroys idea and a query, using a number in a formatted field of a grid control to display a colored text. Looks like this:

C.PNG (7.94 KiB) Viewed 4962 times

The query gives back 0 or 1, and the field is formatted like this:

Code: Select all

[<=0][RED]"ATTENTION, less than -50!!!";[>0][BLACK];General

The query gives back 0 or 1, and the field is formatted like this:

Code: Select all

[<=0][RED]"ATTENTION, less than -50!!!";[>0][BLACK];General

Yes, that is a good solution for a grid or list fed by a query rather than directly by a table.

I expect there are other ways to approach this as well, so I have some more study to do. Many thanks for taking the time to help.
Cheers,
