Hi,
if it is wired to two controls, it will run twice, no question about that -
this has nothing to do with SQL Server's subqueries :-). Controls do not
know about each other unless it is explicitly somehow stated by the page
developer. Controls cannot assume much about logic - like the logic run on
their Prerender event , as the assumption could be wrong, too.
Instead of hardcoding the controls in the event handler, you could rely on
event being raised for specific control and deal with only it.
You could for example run it like this:
//Wiring events somewhere
tbPswd1.PreRend er += new EventHandler(tb PasswordPreRend er);
tbPswd2.PreRend er += new EventHandler(tb PasswordPreRend er);
protected void tbPasswordPreRe nder(object sender, EventArgs e)
{
//Use the knowledge that control raising the event is available via
sender argument
TextBox tb=(TextBox)sen der;
tb.Attributes["value"] = tb.Text;
}
When it works equally for all TextBoxes you assign this handler to.

i'm not sure how the preRender event gets handled.
if i have a function:
protected void tbPasswordPreRe nder(object sender, EventArgs e)
{
tbPswd1.Attribu tes["value"] = tbPswd1.Text;
tbPswd2.Attribu tes["value"] = tbPswd2.Text;
}
and set the two text boxes Prerender event to this single function will it
fire twice?
I'm hoping that dot.net is smart enough to do it oncelike the way
sqlserver
handles some sub queries.
