I have a label in a formview(label1) bound to a datasource.

(ref:- This label's text updates everytime a dropdown control is changed).

How do I show the value of this label outside the formview in (i) a another label (label2) on the main page or (ii) in a label in another formview?


At the moment, for (i)  I have tried :-

protected override void OnInit (EventArgs e)
{
FormView1.ItemCreated += new EventHandler(FormView1_ItemCreated);
base.OnInit(e);
}

protected void FormView1_ItemCreated (Object sender, EventArgs e)
{
FormViewRow row = FormView1.Row;
Label lbl =((Label).row.FindControl("Label1");
Label2.Text= lbl.Text;
}

.............For some reason Label2 remains blank with this code...

If you want to pass the value onto another page, you have some options--QueryString, Session, temporary cookie

You cannot get the text from the label when ItemCreated because the label contains nothing at that time.  You should do it in the DataBound event.

aspx:

            <asp:FormView ID="FormView1" runat="server" OnDataBound="FormView1_DataBound">
                <ItemTemplate>
                    <asp:Label ID="label1" runat="server" Text='<%# Eval("field1") %>'></asp:Label>
                </ItemTemplate>
            </asp:FormView>
            <br />
            <asp:Label ID="Label2" runat="server" Text="Label"></asp:Label>


Code behind:

    protected void FormView1_DataBound(object sender, EventArgs e)
    {
        this.Label2.Text = ((Label)FormView1.FindControl("Label1")).Text;
    }

Regrading the second part of your question, you can assign the text to a label inside another formview provided that the formview has been bound to a valid record (so that the label inside it is created).
