如何在Xamarin.Forms中进行数据绑定

Question

I am new to Xamarin.Forms. I have an xaml file, that includes a label. Also, I have instance of a custom object called tempObject . It is of type TempObject .

I need to display values of TempObject on my UI.

TempObject has Name and Description as public string element.

I tried following code:

<Label Text="{Binding ElementName=tempObject , Path=Name}" TextColor="#0099DC" />

It throws exception.

Could you please help me how to bind an object to Labels in my xaml file.

What is the BindingContext in your page? Using the ElementName is not correct in this scenario.

You can use the {Binding tempObject.Name} if tempObject object available in the context
