In the DataGrid (wijmo) event, there is prepareCellForEdit,

This event does not occur when using the DataGrid.

Is it possible to catch the prepareCellForEdit event in OutSystems' DataGrid?

please teach me.

Hello Yuichiro,

I prepared a sample for showing how you can do it.

Hope I could help!

Thank you for providing the sample.

Looking at the sample I received, I confirmed that the logic of prepareCellForEdit is as follows.

GridOS.ExternalAPI.afterGridInit = () => {

     var gridId = GridOS.GridObject [0] .gridId;

     GridOS.ComponentUtils.getGridObjectById (gridId)



         .addHandler ((grid, e) => console.log ('your event goes here!'))


When I check the Console log, I don't see "'your event goes here!'".

The Grid version is 2.13.3, but this doesn't matter, right?

What's wrong?

Hello Yuichiro,

The prepareCellForEdit is triggered only when you start editing a Cell.

Could you please explain to me what are you trying to achieve? This way I can try to help you in the best way.

Kind regards

I am grateful for your help.

I can't seem to catch the prepareCellForEdit event and this Javascript doesn't work.

I've set this Script to Javascript on WebScreen, do I need any other support related to this Script?

What I want to do with this Script is that when a date type item is hovered over, I want to leave it unset instead of setting the system date by default.

Hello @Yuichiro Tada,

It seems that the code presented in the sample that Ricardo provided can only be used in version 2.18.0 or later.

As a workaround for this, I would suggest the following code:




       .addHandler((grid, e) => console.log('your event goes here!'));


Hope this helps,

Best Regards,

Tiago Pereira
