Question

This post intends to give all the possible solutions to a very common and time consuming issue in Silverlight where bindings don’t work.

<TextBox Text="{Binding TextValue}"/>

public class ViewModel
{
    // ...
    public string TextValue { get; set; }
    // ...
}

Suppose either the property or the TextBox won’t refresh properly.

Answer 1

The binding has a different datacontext.

This example won’t work since the item template has a different datacontext:

<ListBox>
    <ListBox.ItemTemplate>
        <TextBox Text="{Binding TextValue}"/>
    </ListBox.ItemTemplate>
</ListBox>
