Very basic ASP.NET question

[Mike Christie]

I've got some Java experience but no JSP or ASP and am trying to get to grips
with ASP.NET. I'd appreciate some help on a simple question.

I have been able to get databinding to work, and can display a string obtained
from the database on the screen by binding it to a label. However, if I have
an object instantiated in the page's scope, it seems like there should be an
easier way to output a string that I obtain from that object. I gather that
in JSP there was some syntax like:

<%= myObject.aStringProperty %>

that would substitute the value of this as a literal in the middle of the
html. I tried this syntax in ASP.NET with no luck; is there something
analogous? The reference I'm using (Wrox's "Professional C#") while pretty
good in many ways is a bit light on detailed ASP examples, and I couldn't find
anything about this in the ASP tutorials I looked at.

Thanks for any help.

Mike

When you are dealing with data objects, you are not really dealing with a
string property, more an item of a datatype that may contain a string. Try
reading this, it explains a lot about databinding and covers the area you
are asking about with soem useful examples and code.

In your HTML put

<asp:Label ID="lblID" runat="server"><%# myStrvar %></asp:Label>

In your Codebehind put in C#

private void Page_Load(object sender, System.EventArgs e)

{

myStrvar = "Hello Universe";

Page.DataBind(); // you need this

// Put user code to initialize the page here

}

Sorry missed declaring 'myStrvar'

protected string myStrvar;

private void Page_Load(object sender, System.EventArgs e)

{

myStrvar = "Hello Universe";

Page.DataBind();

// Put user code to initialize the page here

}
