Problem with invalid pasted HTML

[Gavin]

Hi,

I have an issue with users pasting invalid HTML into the editor (usually from an email client).  The HTML comes in with no closing tags, which then causes issues when we render the saved content onto a web page.

Example

<span style>some text<span style>more text <span style> some more text

Is there any way to either strip the invalid tags out or add the closing tags when the user pastes the data?

Thanks

Gavin.

Hello Gavin,

You can create your own custom content filter that strips the undesired HTML content. This demo—http://demos.telerik.com/aspnet-ajax/editor/examples/contentfilters/defaultcs.aspx—showcases how to implement one.

Hi Ianko,

We don't give the option to see the HTML, only design view.  Can you do this on paste?

I was hoping that there was some was of validating or repairing when the data is added.

 

Cheers

Hi Gavin,

The content filters also execute on submit, therefore, you can  use them even if the HTML mode is not enabled.

However, you can interact with the pasting by handling the OnClientPasteHtml event.
