Hi!

 

I want to enable/disable row editing in a grid based on a value of a cell (linked to a dataset).

 

I tried beforeedit event but without success.

 

Thx!

BeforeEdit Even will work, try

 

procedure TForm1.QryMainBeforeEdit(DataSet: TDataSet)

begin

if QryMainColor.AsString<>'Green' then Abort;

end;

Thx! Sometimes we forget to use the easy way! I was trying with ajax.

 

It worked now, but required a change.

 

The grid immediately posts the changes or abort the operation based on a column value.

 

 

 

In Grid.ExtEvents->ValidateEdit

 

function OnValidateedit(e)

{

ajaxRequest(UniFrameTransf.GridTransf,

'ValidateEdit',

['val='+e.value]);

}

 

 

 

In the Grid.OnAjaxEvent

 

procedure TUniFrameTransf.GridTransfAjaxEvent(Sender: TComponent; EventName: string;

Params: TStrings);

begin

if EventName='ValidateEdit' then

begin

AbortEdit := AdoQueryTransf.FieldByName('OPERACAO').AsString='R';

 

if not AbortEdit then

begin

if not (AdoQueryTransf.State in ([dsEdit, dsInsert])) then

AdoQueryTransf.Edit;

AdoQueryTransfQUANTIDADE.Value := Params.Values['val'];

AdoQueryTransf.Post;

end;

end

end;

 

 

 

In TADOQuery.OnBeforeEdit

 

procedure TUniFrameTransf.ADOQueryTransfBeforeEdit(DataSet: TDataSet);

begin

if AbortEdit then

Abort;

end;

 

 

 

Declare AbortEdit as boolean in private.

 

 

Thx!
