[Solved] HyperlinkColumn in GridView - problem with CallTo: links

[Yhnavein]

Hi, is there any way to make values in column GridViewHyperlinkColumn clickable?
THere is no problem with standard links or mailto: links, but callto: just doesn't work at all. On click I get following error:
Webpage error details
Message: Unterminated string constant
...
Message: Unhandled Error in Silverlight 2 Application Failed to navigate to callto:[phone].   at MS.Internal.NavigationHelper.Navigate(Boolean checkUserInitiatedAction)
   at System.Windows.Controls.HyperlinkButton.OnClick()
   at System.Windows.Controls.Primitives.ButtonBase.OnMouseLeftButtonUp(MouseButtonEventArgs e)
   at System.Windows.Controls.Control.OnMouseLeftButtonUp(Control ctrl, EventArgs e)
   at MS.Internal.JoltHelper.FireEvent(IntPtr unmanagedObj, IntPtr unmanagedObjArgs, Int32 argsTypeIndex, Int32 actualArgsTypeIndex, String eventName)

If I use standard HyperlinkButton somewhere on my form and set it's url to callto:[phone] - then it works great
Any ideas? :>

Hi Peter,

I tried to use the callto with a standard HyperlinkButton (outside RadGridView) but it throws exception as well.

<HyperlinkButton NavigateUri="callto:+359xxxxxx" Content="Call me" />

where the xxxxx is a valid number.

Can you tell us how exactly you made it work?

Hmm... There is an issue with Silverlight and links 'callto:'. So, our workaround for this problem was creating new Control based on a HyperlinkButton and overriding OnClick method with this one:

protected override void OnClick()
{
    if (this.NavigateUri.AbsoluteUri.StartsWith("callto:"))
    {
        System.Windows.Browser.HtmlPage.Window.Navigate(this.NavigateUri);
    }
    else
        base.OnClick();
}

I really forget about it and it looks like that kind of workaround probably is also necessary for solving my problem. Unfortunately I don't have my company's notebook to check if there is possibility to do same with HyperlinkColumn or, eventually with GridViewCell.
