MultiBinding | WPF Tutorial pdf

MultiBinding allows you to create Binding based on more than one Binding. You can create a class from IMultiValueConverter which will allow you to covert multipleBinding statements into one single output.
The only difference between a normal converter and MultiValueConverter is a normal IValueConverter takes one value as argument whereas a MultiValueConverter takes an Array of values from all the Binding elements.
We will discuss more on MultiBinding later in the series.
<Button x:Name="NextImageButton" >
<Button.IsEnabled>
<MultiBinding Converter="{StaticResource
SelectedItemIndexIsNotLastToBoolean}">
<Binding Mode="OneWay" ElementName="ImageListBox"
Path="SelectedIndex" />
<Binding Mode="OneWay" ElementName="ImageListBox"
Path="Items.Count" />
</MultiBinding>
</Button.IsEnabled>
<Image Source="Icons/navigate_right.png"/>
</Button>
