I feel stupid but cannot find out how to add a text to a WPF Label control in code. Like following for a TextBlock:

DesrTextBlock.Text = "some text";

What is equivalent property in Label for doing it?

DesrLabel.??? = "some text"; //something like this

Try DesrLabel.Content. Its the WPF way.

    its just the ContentControl way actually.

    That seems a bit inconsistent, given that the property is called Text for a TextBox but not for a TextBlock...

    @BlueRaja-DannyPflughoeft there is no obligation for the content of a Label to be text. It is of type object, so you can make it any WPF or .NET type you like - a button, an image, a green rectangle, even a SqlDataReader if you really want! (though quite what that would represent in a label, I'm not too sure...)

  • when update .Content for a WPF label, it does not always refresh the label. How do we force refresh when control yields to the UI?

In normal winForms, value of Label object is changed by,

myLabel.Text= "Your desired string";

But in WPF Label control, you have to use .content property of Label control for example,

myLabel.Content= "Your desired string";

I believe you want to set the Content property. This has more information on what is available to a label.

You can use the Content property on pretty much all visual WPF controls to access the stuff inside them. There's a heirarchy of classes that the controls belong to, and any descendants of ContentControl will work in this way.

you can use TextBlock control and assign the text property.

    While this code may answer the question, it would be better to include some context, explain how it works, and describe when to use it. Code-only answers are not useful in the long run.
