ASP.NET Help

I'm have a user control that gets a value from a cookie and also looks at a db and gets a value from that, these values are put into labels.

The values are UserName.Text and InBox.Text

Code:

<asp:Label ID="UserName"
                runat="server" Font-Names="Verdana" Font-Size="X-Small" Width="92px"></asp:Label>

<asp:Label ID="InBox" runat="server" Font-Names="Verdana" Font-Size="X-Small"></asp:Label>

This user control is then inserted into many pages.

What i want to do is use the values of UserName.Text and InBox.Text in the web form .aspx page that the control sits in. I could just do the connections again but seems to waste a DB connection when the values are in the UC.

Been struggling wwith this for ages, i'm sure its simple.

Any ideas?? (with a code example is poss)

Personally I hate using these user controls, as you lose a certain amount of control. I set up as eg:

In ASPX file
<div id="UserName" name="UserName2" runat="server"></div>
<div id="InBox" name="UserName2" runat="server"></div>

Then in my code behind I would have:

public class _default : System.Web.UI.Page
{
protected System.Web.UI.HtmlControls.HtmlGenericControl UserName;
protected System.Web.UI.HtmlControls.HtmlGenericControl InBox;

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

//.. do DB query
UserName.InnerHTML = "whatever from DB";
InBox.InnerHTML = "whatever from DB";

// Can now squirt my DB data into anything else on the page as well, without doing another query
}
}

I'd suggest creating some public properties in the user control and access them from the base page. If you want to isolate the usercontrol from outside changes make the property read only.

I don't know what language you're using so if it's not VB.NET and you don't understand it let me know and I'll translate.

In your usercontrol

Code:

'Username
Public ReadOnly Property TheUsername() As String
    Get
        Return Username.Text
    End Get
End Property

'InBox
Public ReadOnly Property TheInBox() As String
    Get
        Return InBox.Text
    End Get
End Property

Then in your base page you can do this (I've assumed the control ID is MyControl)

Code:

        Dim strUsername As String = Me.MyControl.TheUsername
        Dim strInBox As String = Me.MyControl.TheInBox

        'Now do what ever you want
        LocalLabel.Text = strUsername & " " & strInBox

Any problems let me know.
