Hi!

Let's say I have a usercontrol called LabelHolder. Within that I have a label like this:

<asp:Label ID="lbCan" runat="server" Text=""></asp:Label>

In a page that holds that user control (lets say Deafult.aspx) how do I (without using the FindControl method, as it is inefficient) get to set the label text property from the Default.aspx.cs file

So what I wish for i something like:

C#

public partial class Default : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        LabelHolder lH = new LabelHolder();
        lH.lbCan.Text = "foo"; //This is what I wish would work but it doesn't
        form1.Controls.Add(lH);

    }
}

Very greatful for any tips!

Thanks

You could add an accessor property to your LabelHolder control to do it for you.

C#

public class LabelHolder
{
....

  public string Text
  {
    get
    {
      return lbCan.Text;
    }
    set
    {
      lbCan.Text = value;
    }
  }
}

so your code becomes

C#

public partial class Default : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        LabelHolder lH = new LabelHolder();
        lh.Text = "foo"; 
        form1.Controls.Add(lH);

    }
}

Solution 2

Create a Property in the user control:

public string Name
{
set { lbCan.Text = value; }
get { return lbCan.Text; }
}

In the the Default.aspx page just assign a value to that property.

ucTest.Name = "hasan";
