Bind ASP.NET to a property of a class

[ezazazel]

Hi folks! Maybe anyone can help me with this. I'm from WPF world and am used to bind to objects in other classes. I found many examples to bind to lists, but none how to bind to a property of another class. So here's the deal: Default.aspx.cs

private DefaultVM vm;

protected void Page_Load(object sender, EventArgs e)
{
this.vm = new DefaultVm();
}

DefaultVM.cs

public int TestValue { get;set;}

public void DefaultVM()
{
TestValue = 10;
}

Default.aspx

<asp:Label runat="server" Text='<%# DataBinder.Eval(vm,"TestValue")%>'/>

None of this works. Tried a few other things as well, but without result. What am I doing wrong?

Try this:

then, in Default.aspx.cs (perhaps in OnLoad or wherever you deem appropriate)

vm = new DefaultVM();
lblTest.Text = vm.TestValue.ToString();

Mod: Sorry, yes, just thought: that probably wasn't the answer you were looking for. Make private DefaultVM vm; to public DefaultVM vm; that should do it.

Thank you! That did it:

'<%# DataBinder.Eval(DataItem.vm,"TestValue")%>'

and defining

public DefaultVM vm;
