Hello Mas,

You can detect when a hyperlink is deleted from your document using the following approach:


I hope you find this solution useful. Please don't hesitate to ask if you have further questions.

Thanks for the reply, but I don't think this approach work well.

Using this approach, my deletion procedure called even if I only remove a character on the hyperlink, not all 'hyperlinked' character (character with underline and blue color).

Usually, user will expect that removing not all characters on a hyperlink does not remove the hyperlink itself but only to modify the link to click.

I wonder if I can detected whole link deletion by detecting HyperlinkRangeEnd ? Or any other 'event' fired when the link is totally removed from document ?

 

Hello, Mas,     

By design, the hyperlink is removed when you delete a single character from the specific URL. Although a part of the URL may be remaining, it represents a plain text and it won't navigate you anywhere. A RemoveHyperlinkCommand is executed when you right click over a hyperlink and select the Remove Hyperlink menu item. This can be handled by the previously provided code snippet by my colleague, Dimitar.

However, if you simply click Backspace at the end of the hyperlink, you can detect the HyperlinkRangeEnd and extract the URL as follows:


Note that the hyperlink is removed at this specific moment and the rest of the text is just a plain text. There is no specific event that can be handled when the whole text is deleted from an initially existing hyperlink. The CommandExecuting event is fired for each document's manipulation. Hence, you can use it to initially extract the URL and detect whether the document contains this URL.

I hope this information helps.

Merry Christmas

Hi Dess,

I have apply your code into my application but I still have complain from my user. 

Lets say I have link like this: *thislink*

When user select all *thislink* and pres delete (or backspace), your code failed to detect the link deleted.

HyperlinkRangeStart hyperlinkRangeStart = this.GetCurrentInnerFieldRangeStart();

return null, failed to detect the link. 

HyperlinkRangeStart hyperlinkRangeStart = this.GetCurrentInnerFieldRangeStart();

also retur null. So, there is no way I can detect the deleted Hyperlink.

If user put the cursor inside the link, lets say: *this--cursor--link* and press delete / backspace, your code work like a charm. It also detect the link perfectly when user put the cursor after the link: *thislink*--cursor-- and press backspace.

The only problem is when user select all the hyperlink (the word: *thislink* and press delete). Once more, it also *does not* detect when user use right click on the link and click remove link from context menu.

Do you have any suggestion ?

 

Hi Mas,

Indeed, when a selection is created, it contains more elements and that is why the hyperlink marker cannot be obtained through the position. Here is how I modified the code so it can return the first HyperlinkRangeStart in the current selection:

Please, note that the selection might contain several hyperlinks so you might need to slightly modify the code if you would like to handle this case as well.

Hope this is helpful.
