about UserControl Visible property

[Edward]

hi, everyone,

I've one user control "ctlList" , and one button "View" in the Page, in
the Page_Load event, I set the ctlList.Visible to false, then in the View's
click event, I set it to true.

But the result is when Load , it's really invisible, but Click didn't make
it visible.

where's my fault?

perhaps you didn't put the ctlList.Visible = false inside a postback
check (ie
if not ispostback then
ctlList.Visible = false
end if
)

if so then regardless of what happens in the onclick it still sets it
to false when the page loads.

hth,

I did . below is my code:

void Page_Load(Object Sender, EventArgs e) {
if (Page.IsPostBack == false) {
ctlList.Visible = false;
}
}

void btnGenerateInvoice_Click( Object Sender, EventArgs e ) {
ctlList.Visible = true;
}

Edward,

Make sure ctlList has any data to show on the postbacl. If it is databound,
do you re-bind it again on the postback?
