Question

I have a column in a gridview that has a hyperlink defined in each row.

<TextBlock>
    <Hyperlink Click="btn_Authorise">
        <TextBlock Text="{Binding LinkText}"/>
    </Hyperlink>
</TextBlock>

I would like the hyperlink to execute different code depending on some parameters I bind to it. ie. the user clicks the link and in the code behind it looks at a parameter and opens one of four dialog windows. How can I add a parameter? Should I be using Commands?

I an new to WPF.

EDIT:

Ok – So all I needed to do was add the CommandParameter=”” and I could then handle the rest in the event handler. This is probably not the correct usage of ‘Commanding’.

<TextBlock>
    <Hyperlink Click="btn_Authorise" CommandParameter="{Binding ActionProperty}">
        <TextBlock Text="{Binding LinkText}"/>
    </Hyperlink>
</TextBlock>

Edit: So apparently Hyperlinks also have commanding, which makes this quite straightforward.

See the commanding overview if you are new to commands in WPF.

You could wrap it in a lookless Button and only handle the Button.Click, then you can bind a Command to it and utilize the CommandParameter.

To make a button lookless you can change the Template:

<Button.Template>
    <ControlTemplate>
        <ContentPresenter />
    </ControlTemplate>
</Button.Template>
