C# or VB.NET are welcome.
I have an <%#Eval("FirstName")%> in the aspx page, I want to replace "FirstName" to <%#Eval(employee.FirstName)%> but "employee" object
is instantiated in the codebehind like this:
Public employee As New Employee
How can I call this object in the aspx page? Should I can create an "employee" in the aspx? if so, how to do that.
I desingned a page with tags, Now I want to access object tags in code behind.
This is aspx page code....
<object type="label" runat="server" class="System.Web.UI.WebControls.Label" id="label_priority" parent="-1" bindedfield="priority" empty="1" value="MyValue">
Here I am adding runat=server in object tags it is giving error as
"An object tag must contain a Class, ClassID or ProgID attribute."
then I added class="System.Web.UI.WebControls.Label", now not giving any error but not showing anything in browser.
so My question is how do I access object tags in aspx.cs page? or I want to create a label with object tag that is accessible in code behind.
I am trying to hide or show a certain section of my table depending on the value of a property in my binding object(s).
public class Class1
{
public bool Display { get; set; }
}
In ASP.NET MVC, I can just do the following (assuming that Class1 is the model that binds to the page.)
<table>
<tr>Row 1</tr>
<tr>Row 2</tr>
<% if(Model.Display) { %>
<tr>Row 3</tr>
<tr>Row 4</tr>
<% } %>
</table>
How can I achieve the same behavior in transitional ASP.NET? That "Model" variable is not available. How do I retrieve the data binding object?

I am new to silverlight and I am wondering if it is possible to access silverlight object data from the aspx page that host it. Or have silverlight write to a hidden field on the page on client side.
What I am trying to do is to use silverlight to upload file via WCF (client to WCF Service directly instead of posting data back to the web server then forwarded to WCF service). When uploading a large file, user can still do some data entry etc. And once the upload is done have it write some data return by the WCF service to the aspx's hidden field and postback to the server on submit.

I have a page, Default.aspx, with its own code-behind file like this:

using System.Web.UI.WebControls;
public partial class _Default : System.Web.UI.Page

What I'd like to do is access to "anArray" from a C# class (not tied to a page) declared in App_Code folder. What can I do?
Edit: As said in the first comment, I really apreciate your about refactoring my connection objects. However, what I'm really doing here is to rewrite an old PHP application in order to get comfortable with basic C# and ASP.NET, so this code will never go really live. So, I'm still intersted in a way (if any) to access an object declared in a code-behind code from a standard C# class.
Edit2: I removed the OdbcConnection object in order to focus to the real problem: how to refer to an object istantiated in a code-behind file from a C# class situated in App_Code?
