TUniDBGrid, editing cell and ajax event

[bruno65]

with a inherited grid from TUniDBGrid, inside a editing cell (type integer) i change the initial value 1 to 3 and tab to the next cell.

Then i do the reverse stage : i change the value 3 to 1.

I added JS log like this 

grdListe.ClientEvents.ExtEvents.Values['beforeedit'] := 'function beforeedit(editor, context, eOpts) { console.log("----------------"); console.log("beforeedit:value="+context.value) }';
grdListe.ClientEvents.ExtEvents.Values['edit'] := 'function edit(editor, context, eOpts) { console.log("edit:originalValue="+context.originalValue); console.log("edit:value="+context.value) }';

For the reverse stage, i check values inside Chrome browser in 2 ways :

•  with the console panel :

----------------
VM1127:1 beforeedit:value=3
VM1127:1 edit:originalValue=3
VM1127:1 edit:value=1

• with the network panel , the payload of HandleEvent gives :
• Ajax=1&IsEvent=1&Obj=O9D3&Evt=beforeedit&V=3&O=3&R=2&C=9&RN=2&_S_ID=VFPzskQn8V10E1BC7DD&_seq_=36
• Ajax=1&IsEvent=1&Obj=O9D3&Evt=edit&VR=&V=1&O=1&R=2&C=9&RN=2&_S_ID=VFPzskQn8V10E1BC7DD&_seq_=37

I don't find why for the Edit Event O=1 because i expected to be 3 (not 1) like the console log (originalvalue).

Any idea how 'O' can be changed to 1 ?

Note : the consequence is that TUniCustomDBGrid.SetCellValue() will not call SetFldValue() because uniVarsEqual(OldValue, NewValue) is True

What kind of events (in client side or server side) can change the parameter O=3 to O=1 between beforeedit and edit javascript events ?

Hello,

Sorry, your case is not clear to me. 

[bruno65]

look at the column 'Quantité' in the DBGrid and the events beforeedit and edit

then i change the value from 1 to 2 and TAB

finally  i change the value from 2 to 1 and TAB

Why the parameter 'O' equals 1 and not 2 ?

Therefore as 'O' = 'V' the data field 'Quantité' won't be updated to 1. ( clicking in an other record then the cell 'Quantité' shows 2)
