Hello

I 've got a form grid where i have rows, i need to create some behavior.

When i click the checkbox on row1, the other checkbox from row2(row3,4 ...) must be disable, but not the one i checked first and when i uncheck the checkbox on row1, the other checkbox from row2 must be enable.

How to do that ?

Here's the grid sample.

Regards

Hi,

Do you mean that if one checkBox in the grid is ticked as true, then all other records should have their checkBoxes as disabled? And if no checkBox in the grid is ticked as true, then all checkBoxes should be enabled?

If yes, then on the modified method of the checkBox, you can check if the current value is true and disable all other checkboxes in the grid (recId != CurrentRecId) and if the value is false, then you can enable all of them. I think you would also need the code in the init method of the form so that the code is reflected when you first open the form

Maybe show us your code and we can help you from there

Or why not on the validate method only allow one checkbox to be ticked as true? Would it suit your requirement? I mean if you try to tick another checkBox a warning will appear saying only one checkBox can be set as true and it will prevent you from saving

Thanks,

In the active method of that line datasource just check if any of the other line is checked. If checked then make the current row enum field disabled and vice versa.

Hi guys,

Thanks for replying.

You must understand that when i'm checking the checkbox on a specific row, only other ones must be disabled, the checked one must be editable in case i need to uncheck it to make other ones enabled.

For now, i tried many ways but i'm not able to make enable the checked on when disabling the others.

Do you have some clues ?

Regards.

Hi Awwax,

Yes i understand that's why i said where recId!= currentRecId and that's why i mentioned modified method and init method

So for example in general, if let's say the grid is salesLine, and you would like to get all other records except for the one you are standing on, then you would write sth like this:
While select salesLine where salesLine.SalesId == this.SalesId && salesLine.RecId != this.RecId

Can you show us what you did and tell us the wrong behavior that happens so that we can help

The active method could also work as bharani suggested -- maybe it's a better suggestion and maybe what i suggested at first won't work.
You could write sth that says if no checkBox is ticked as true in the whole grid then make all editable
If one is ticked as true, then make others disabled

So maybe try sth like this:
[ExtensionOf(formDataSourceStr(SalesTable, SalesLine))] final class SalesTableFormDatasource_Extension { public int active() { int ret; ret = next active(); if(ret) { SalesLine salesLineLocal = this.cursor(); SalesLine salesLineCount; select count(RecId) from salesLineCount where salesLineCount.SalesId == salesLineLocal.SalesId && salesLineCount.CheckBoxField == NoYes::Yes ; If (salesLineLocal.CheckBoxField == NoYes::Yes || salesLineCount.RecId == 0) { this.object(fieldNum(salesLine, CheckBoxField)).allowEdit(true); } else { this.object(fieldNum(salesLine,CheckBoxField)).allowEdit(false); } } return ret; } }

Thanks,

Hi,

I have a question about this requirement: what should be the default case? Do all lines have to be enabled or disabled?

Thanks,

Hello guys,

I used a validate method and add a warning, that's seems to me the best solution.

Thanks guys
