SSL and HTMLPlaceHolder

[Jonathan]

Is it possible to get the HTMLPlaceHolder to work with ssl site that is at https?

[Petar Mladenov]

Hello Jonathan Marbutt,

There are no known issues when using https site in the Source of the RadHTMLPlaceHolder:

<telerik:RadHtmlPlaceholder SourceUrl="https://encrypted.google.com/"/>

The above example works fine.
Feel free to ask if you need further assistance.

Ok it works in browser, but can we make it work out of browser? It works for http but not https on out of browser.

I get:

Set property 'Telerik.Windows.Controls.RadHtmlPlaceholder.SourceUrl' threw an exception. [Line: 8 Position: 47]

Hi Jonathan,

In out-of-browser scenarios, RadHtmlPlaceholder uses the Silverlight's WebBrowser control internally to render HTML content. I've tried for example the following:

<Grid x:Name="LayoutRoot" Background="White">
    <WebBrowser Source="https://shipit.ubuntu.com/" />
</Grid>

...and received the following error:

Failed to assign to property 'System.Windows.Controls.WebBrowser.Source'.

Since the WebBrowser control does not support certain HTTPS sites, I don't think we can do much about that. However, we will continue our research on the topic since there is not much information available. I'll let you know if we stumble on something helpful.

Kind regards,

Thanks, 

By "certain" ssl sites, is there something we could do to configure our SSL differently to make it work?

Hi Jonathan,

Sorry it was my mistake. I was left with the impression that some HTTPS websites can be opened with the WebBrowser control. However, I tried like 15 random sites and all of them returned the Failed to assign to property 'System.Windows.Controls.WebBrowser.Source' exception. In my opinion, I don't believe there is a way to configure the WebBrowser so that it displays HTTPS sites.

Hello Petar 

Can you please confirm me whether we can open HTTPS website in RadHtmlPlaceHolder control?

Hello  Kiril,

Can you please confirm me whether we can open HTTPS website in RadHtmlPlaceHolder control?

Hi Yogendra,

As Kiril stated back in 2011, the requested behavior cannot be achieved because of the limitation of the native Web browser control. Since the RadHtmlPlaceholder uses it, our control is not capable of visualizing HTTPS sites.
