Hi,
I have a search bar as a User Control sitting on a Page. The asp web control
search button has its OnClick event set to a method "Search" which sets a
bool isSearch to true.

When I try to access this variable on the main page, it always comes up as
false. I think this is due to the main Page being loaded before the Search
method in the User Control is run.

How am I able to run the Search method in the User Control before the main
Page loads? - or is there a better way of dealing with this situation?

many thanks,

Pete

You can 'register' an event in your Page to listen for an event from your
user control by creating a delegate:

public delegate void TestPointSelectedHandler (object sender, ushort
testPointID);

and then create an event in your control that calls the delegate:

public event TestPointSelectedHandler TestPointAdded;

Then raise the event via something like:

TestPointAdded(this, ushort.Parse(strSysID));

In your page you can have something like:

Control1.TestPointAdded += new TestPointSelectedHandler(addTestPoint);

With a method that does something:

private void addTestPoint(object sender, ushort testPointID)
{
// Do some work here
}
