[Solved] Styling and enabling the ToolTip

[Samson]

Hi, I'm new to silverlight and telerik controls and I'm wondering if it is possible to style the ToolTip on the RadRich TextBox I'm looking for it to be red with white text. Also was wondering if it is possible to control when the tooltip appears, for example I only want it to be enable  when a certian condition is met  is this possible?

Hello Samson,

If I have understand your question right, you want to set a tool tip of the RadRichTextBox control itself, which to have custom style. You also want this tooltip to be enabled in certain cases.

About the custom styles - the answer is yes, you can have custom styles and templates. For more info see here.

To enable/disable tooltip - you can try setting/removing the tooltip using ToolTipService.SetToolTip(radRichTextBox, toolTip);/ToolTipService.SetToolTip(radRichTextBox, null); respectively.

Hope this helps!

But is there a way to remove a tooltop of a Hyperlink in the HyperlinkClicked event? We want to clear out that Url and "Click to follow link" tooltip once clicked.

Example snippet:

private void rtBox_HyperlinkClicked(object sender, HyperlinkClickedEventArgs e)
{
   Hyperlink link = sender as Telerik.Windows.Documents.Model.Hyperlink;
   ToolTipService.SetToolTip(link, null);
   ...yada yada more code

The example code above does not seem to fire when a link is clicked.
And setting the tooltip on the whole RichTextBox does nothing.

Hi Bob,

The only customization you can apply to the tooltips of hyperlinks is by setting the HyperlinkToolTipFormatString of RadRichTextBox. The format you specify will be applied to all hyperlinks is the document.
Introducing different tooltips for links is on our to-do list, but has not been scheduled yet. You can use this PITS issue to track our progress: Pits Issue #6953.
On a side note, I could not find a case where the HyperlinkClicked event is not properly fired. However, the sender is not a Hyperlink. Hyperlinks have been obsoleted, due to the new functionality we have introduced (inserting bookmarks, embedding tables and images in the hyperlink, etc). The links in the document are marked by two inline document elements - HyperlinkRangeStart and HyperlinkRangeEnd. In between, you can have all kinds of elements, as long as they specify a valid document preserving the document structure. Thus, the sender is the Span or ImageInline you have clicked. As they are not UIElements, you cannot set the tooltip using the code in your snippet. 
Do you want to preserve the hyperlink in the document? Because it will be possible to remove the hyperlink, thus clearing the URL and tooltip. If that will suit your scenario, but you have trouble implementing it, we can assist you further.

No, our issue is if you mouse over the hyperlink you get the Url as a tooltip, and if you don't move your mouse when clicking, the content swaps out for new content, but the tooltip stays there for 5 seconds on top of the new content, again, not moving the mouse at all. Noting we're using the Silverlight TransitioningContentControl to add new content to. Even tried in the RadRichTextBox's Unload even to set the opacity/visivility/etc to hide the entire control on it's way out(which only takes a split second), but the tooltip remained.

I believe our version of the control(s) is 2010.3.1314.1040, by looking at the version of Telerik.Windows.Controls.RichTextBoxUI, and the other Telerik references. So maybe this "tooltip not clearing" bug has been fixed if there is a newer version of the conrol.

Sorry I can't share screenshots or code, it's an internal LOB app.
