I understand that in Business Central, custom action buttons can be disabled automatically when multiple records are selected on a list page if action button does not have OnAction trigger.

But how can a custom action button that includes an OnAction trigger be disabled.

For context, I need to run code from the action button 'test action' for a selected record, but I want the button to be disabled when multiple records are selected.

thanks

Namaste @Ahsan baig 123

Can you do below things and verify . We usually do this to make action visible and to execute script.

1) Remove Page-Link and add necessary filters to table and run the action

2) Add below Properties

3) Add script in Trigger - OnAction() . I used xmlport , you can use your object

IF you feel this helped , Mark as "Verified"

Hi,

Business Central does not automatically disable actions with OnAction when multiple records are selected. You must handle it manually.
Solution: Use the OnAfterGetCurrRecord trigger (or OnOpenPage) to check if multiple records are selected and control the Enabled property via a Boolean variable.

Example:

pageextension 50100 CustomerListExt extends "Customer List"
{
actions
{
addlast(Processing)
{
action(MyAction)
{
Caption = 'My Action';
Enabled = EnableMyAction;
trigger OnAction()
begin
// Your logic here
end;
}
}
}

var
EnableMyAction: Boolean;

trigger OnAfterGetCurrRecord()
var
SelectedRecs: Record Customer;
begin
CurrPage.SetSelectionFilter(SelectedRecs);
EnableMyAction := SelectedRecs.Count = 1;
end;
}

This disables the button when more than one record is selected.

Thanks

Rishabh

Why not to give an error message when multiple records are selected, instead of hiding it.

Hi Ahsan,

Use a Boolean bound to Enabled and recompute it from the current selection.
CurrPage.SetSelectionFilter gives you the selected rows; disable the action unless exactly one row is selected.
This keeps the button disabled when multiple records are selected, while still running your OnAction code for a single selection.

Please mark “Verified” if it helps.
