Subject: [aspngvb] Dynamically Adding Controls to an aspx page

Folks,
I currently have a page set up that dynamically adds controls to a web =
page
(textbox, and calendars, also labels). The controls are adding =
correctly. =20

My issue is placement. Basically I place a label, then the textbox, or
calendar control after the label. I want a line break between each of
these, but have not figured out how to do this. Any ideas? I tried
creating a literal with "<br>" as the text, but that doesnt work. Below =
is
the code:

dim oEntry as new textbox()
dim oLiteral as literal()
dim oLabel as new Label()

oliteral.Text =3D "<br>"
Controls.Add(oLabel)
Controls.Add(oLiteral)
Controls.Add(oEntry)
Controls.Add(oLiteral)

The label still displays on the same line as the textbox.
Any ideas? TIA

Bryan, thanks for your interest.
Actually this site has the same code, simple format:
http://aspauthors.com/aspnetbyexample/ch06/

Reference 6.4 (third example)
Here as in my case, you need to click on the update button which then =
fires the selecteditemchange event to see the text message in the label.
I want the event to fire and the message to show as soon as the =
selection in the drop down list box is changed.
Again, thanks for your interest.

That sample isn't using the AutoPostBack.

put AutoPostBack="True" in the <asp:DropDownList tag.
