LinkDecorator with custom link text

Hi,

is it possible to use a LinkDecorator and still get the link text from
the DataProvider without overriding the render method in Decorator?
The examples show only static text when using LinkDecorator (Either
"Edit" or "Delete"). Can I get the link text by property?

Thanks!

Hi,

I solved the problem. Maybe my solution will be a better a explanation
to the problem:

I checked the source of the LinkDecorator and found this method:

[code]

/**
     * Render the link to the specified buffer.
     * <p/>
     * If this method is overridden to add extra parameters to the link,
     * remember to invoke <tt>super.renderActionLink</tt> so default rendering
     * can continue.
     *
     * @param buffer the specified buffer to render the link output to
     * @param link the link to render
     * @param context the request context
     * @param row the table row being rendered
     * @param value the value of the link
     */
    protected void renderActionLink(HtmlStringBuffer buffer, AbstractLink link,
        Context context, Object row, Object value) {
        link.render(buffer);
    }


[/code]

Thus I solved my problem by overriding the renderActionLink in LinkDecorator:

[code]

public class LinkDecoratorWithDataProviderContent {

  @Override
  protected void renderActionLink(HtmlStringBuffer buffer, AbstractLink link,
        Context context, Object row, Object value) {

        if(row instanceof Post) {
           // Set the TEXT, which is displayed by <a href>TEXT</a>.
Otherwise the name attribute of the link is written to <a href></a>
           link.setLabel(post.getTitle());
        }

        super.enderActionLink(buffer, link, context, row, value);
    }
}

[/code]

Cheers

Hi,

The "edit"/"delete" text is normally set on an ActionLink control. You can set the text of the 
ActionLinks to anything you like.

Hi, Kiril! Welcome to Click community!

Can you better elaborate your question? I did not understand it. Do you
understand the Decorator Design Pattern' idea[1]?

Gilberto
