Setting multiple labels with same text

Question

We do internatializing (sp?) by this:

<asp:Label ID="labelPhone" runat="server"></asp:Label>

Then in the aspx.cs:

labelPhone.Text = (string)GetGlobalResourceObject("lang", "Phone") + ":";

But then if there are more labels I have to repeat:

labelPhone2.Text = (string)GetGlobalResourceObject("lang", "Phone") + ":";
labelPhone3.Text = (string)GetGlobalResourceObject("lang", "Phone") + ":";

Can this be avoided?

Like jQuery giving all identival labels the same class, then assigning text to that class:

 $(".phonelabel").text("Telefon:");

Have you checked how ASP.NET localization works? You don't need to set individual labels. You could refer to the resource key directly, eg: Text="<%$ Resources:Label1TextKey %>". You could also use templates for specific fields, eg a Phone template that includes the localized label and field. — Panagiotis Kanavos

Where does GetGlobalResourceObject come from? Have you tried using Resource Files ? — Panagiotis Kanavos

In C# you can perform single statement assignment like this:

labelPhone.Text = labelPhone2.Text = labelPhone3.Text =
(string)GetGlobalResourceObject("lang", "Phone") + ":";

or you can do it in a loop:

Label[] labels = new[] { labelPhone, labelPhone2, labelPhone3 };
Array.ForEach(labels, x => { x.Text = 
          (string)GetGlobalResourceObject("lang", "Phone") + ":"; });

OK, I'll go for the first, but I would have preferred I would have been able to just add a new phone label without having to add it to the list of assignments.

I don't think you can check out - stackoverflow.com/questions/19417839/…

@LeifNeland have you checked how localization works in ASP.NET? You don't need to set individual labels, nor do it in the code-behind.

There may be a way to do it using reflection. I will look into it if I have time.

Panagiotis Kanavos Over a year ago

There is no need for reflection. This is a localization question. ASP.NET provides several mechanisms. For example, the text can be set on the tag itself : Text="<%$ Resources:Label1TextKey %>".

u can use this extension method.

public static class ControlExtensions
{
    public static void ForControls<T>(this Control ctrl, Func<T, bool> where, Action<T> action) where T : Control
    {
        if (ctrl is T)
            if (where(ctrl as T))
                action(ctrl as T);
        foreach (Control childControl in ctrl.Controls)
        {
            childControl.ForControls(where, action);
        }
    }
}

using..

            this.ForControls<Label>(
            // you can define any other condition
            c => c.ID.StartsWith("labelPhone"),
            // you can make any other process for this controll
            c => c.Text = (string)GetGlobalResourceObject("lang", "Phone") + ":");

As Panagiotis write:

 <asp:Label runat="server" Text="<%$ Resources:Lang, Phone %> "  CssClass="box" />

If the comment were an answer, i would have selected it as the winner ;-)
