unable fire an event for dynamically created component
I have created a dynamic TClientDataSet component and tried to fire the OnCalcFields event....it has'nt worked. The code looks like this...
table := TClientDataset.Create(Application);
table.OnCalcFields := tableCalcFields; //where 'tablecalcfields' is the method define开发者_如何学Cd by me.
table.FieldDefs := Query1.FieldDefs;
table.CreateDataSet;
table.Open;
Query1.First;
while not Query1.Eof do
begin
table.Append;
for I := 0 to Query1.FieldList.Count - 1 do
begin
table.FieldValues[table.FieldList[i].DisplayName] :=
Query1.FieldValues[Query1.FieldList[i].DisplayName];
end;
Query1.next;
table.Post;
end;
DataSource2.DataSet := table;
table.First;
after this i will edit the information on the dbgrid(datasource2 is setted to it), at this time the event must fire (if you have a design time component it will)
thanks for answers, Vijay
The code doesn't have calculated fields.
