 |
|
Hi,
I'm searching for a component by name like this
ComboBox = (TComboBox *)Form->FindComponent(strName);
and then changing its selected item
ComboBox->ItemIndex = 0;
Since the OnChange-handler of ComboBox isn't activated this way I have to
call it myself.
But how do I get the specific event handler?

Call it like;
OnChangeHandlerName(ComboBox);
ComboBox will be the Sender sent to the Event Handler.

You can call it like this:
if( ComboBox->OnChange )
ComboBox->OnChange(ComboBox);
