A slight variation to suggested code. Instead of creating new ToolTipUIElement you can set the ToolTipItem property on the ButtonUIElement

buttonElement.ToolTipItem = new ToolTipItem("title", "text");

        private class ToolTipItem : IToolTipItem
        {
            readonly string m_toolTipTitle ;
            readonly string m_toolTipText ;

            public ToolTipItem(string toolTipTitle, string toolTipText)
            {
                m_toolTipTitle = toolTipTitle;
                m_toolTipText = toolTipText;
            }

            ToolTipInfo IToolTipItem.GetToolTipInfo(Point mousePosition, UIElement element, UIElement previousToolTipElement, ToolTipInfo toolTipInfoDefault)
            {
                toolTipInfoDefault.AutoPopDelay = 2000;
                
                toolTipInfoDefault.ToolTipText = m_toolTipText;
                toolTipInfoDefault.Title = m_toolTipTitle;

                return toolTipInfoDefault;
            }
        }

Thanks Mike, the sample you referenced has finally put me in the right direction. ToolTips work now with my existing ToolTipManager, so there are no conflicts any more with showing multiple tool tips at the same time.

Basically, I adapted the ToolTipContextHelperForGrid.cs to serve my needs with nested EditorButtons in an UltraTextEditor. Works like a charm :-)

However, there is still some inconsistent behaviour: I have added an UltraListView as a drop down item to my UltraTextEditor. While the ListView is dropped down, ToolTips on the UltraTextEditor will not show. Also, while the UltraTextEditor is in EditMode, ToolTips will only be shown when the mouse pointer is over the border of the control, but not inside it (over the text area, that is).

I have a temporary solution for this by simply checking on the AfterEnterEditMode event and immediately exiting EditMode if not over the drop down button. But I am wondering if there no more elegant solution to this behavior (like disabling edit mode, since there is no need for it in my app anyway)...

Anyway, thanks again for your support.

€: I originally attached my query to this already answered post, because it seemed to be about a similar topic. Is it always better to start a new thread instead?

Hi,

I don't think there is any way for you to force the tooltip to close when you are applying it to the UIElements using a CreationFilter like you have here.

If you are already using an UltraToolTipManager elsewhere in your application, then you could use it for the editor buttons, too.

The down side of this approach is that, since all of the butttons are part of the same control, you will have to handle the showing of the tooltip yourself - you cannot just set the tooltip on the control and then change it as the mouse moves over the button, because once the tooltip is shown for the control, it wil not be shown again until the mouse leaves that control and comes back.

So what I would do is trap MouseEnterElement and watch for when the mouse enters one of the button UIElements. When it does, you apply the tooltip to the entire control and then start a timer. When the timer tick goes off, you show the tooltip.

Of course, if the mouse moves over another button, you will want to restart the timer. If the mouse moves outside of the control, you will want to stop the timer (if it's going).

It's a bit more work, but I think it should be doable.

You might also want to check out the ToolTips with Context sample. This is a sample project that demonstrates using UltraToolTipManager to show different tooltips for different parts of the same control. The sample uses a class which you can copy and use in your code and the modify it to look for the appropriate UIElements.

If you installed the samples with NetAdvantage, you can find the sample I am referring to under a path something like this:

Hello everyone,

I have added ToolTips to my UltraComboEditor's ButtonsRight collection (containing 4 EditorButtons with individual tool tip texts) the way that Brian described above.

Unfortunately, AutoPopDelay doesn't do for me, since I do have other controls in my app that are using an UltraToolTipManager. That way it is possible that multiple tool tips are being shown at the same time.

I would need to determine when the mouse has left the EditorButton's Rect area and hide or reset the currently shown ToolTip respectively, but I can't get it to work.

Code from my UserControl:

private void cmeProfiles_MouseLeaveElement(object sender, UIElementEventArgs e)
{
    EditorButtonCreationFilter creationFilter = cmeProfiles.CreationFilter
        as EditorButtonCreationFilter;
    creationFilter.DisableCurrentEditorButtonToolTip(
        cmeProfiles.UIElement.LastElementEntered);
}

Code from my EditorButtonCreationFilter class:

public void DisableCurrentEditorButtonToolTip(UIElement lastElementEntered)
{
    ButtonUIElementBase buttonElement = lastElementEntered
        as ButtonUIElementBase;
 
    if (buttonElement != null && buttonElement.HasChildElements)
    {
        for (int i = 0; i < buttonElement.ChildElements.Count; i++)
        {
            ToolTipProviderUIElement toolTipElement =
                buttonElement.ChildElements[i] as ToolTipProviderUIElement;
 
            if (toolTipElement != null)
                toolTipElement.ToolTipItem = null;
        }
    }
}

I am pretty new to all this Infragistics stuff, sorry if I couldn't see the obvious. Brian already wrote that he could not figure out how to make the tool tip disappear after leaving the button, but maybe somebody can come up with an idea...

Alternatively, I would probably have to find a way how to use my UserControl's UltraToolTipManager for both normal controls and the UltraComboEditor's EditorButtons.
