As suggested, how could I make a button in c++/cli (Windows Form) invisible and clickable?
I can make it invisible with this->button1->Visible = false;
When clicked it changes a picture changes. Sadly, while invisible, I might as well not have it, since it isn't clickable in this state.
How can I make this invisible button clickable?
To make things not visible but still clickable in WinForms, I'd generally start by setting ForeColor and BackColor to Transparent. However, a button also has things like borders, a dotted line when it has keyboard focus, that type of thing, and I'm not sure you can set all of those colors.
Does it have to be a Button? A plain Control has a much plainer visual look, which can more easily be made invisible, but it still has a Click event. Would that work for you?

I am building a wpf ribbon application. When certain buttons are clicked on, I would like the background to remain "lit up" like when the mouse is over it. I don't want to change the default mouseover color, I just want to replicate it when the button is pressed for "modal" type commands. Is there a way to do this? In MFC programming it would be like adding the "BS_PUSHLIKE" style to the button where it remains lit while active. Thanks for any help you can provide.
I am not sure exactly what you are looking for, but I believe the equivalent of "BS_PUSHLIKE" in WPF is the ToggleButton control.
I have created a custom popup to decorate my buttons with animated tooltips. I track Button.MouseEnter for the button to decide when to display the popup. I use Button.MouseLeave to determine when to hide the popup.
Problem is Button.MouseLeave is fired prematurely if the popup moves over the mouse cursor (its appearance is animated) despite the fact that I have set IsHitTestVisible = false for the popup and all its visual children.
Is this the way WPF is designed to work? I need MouseLeave to only fire when the cursor moves away from the button itself and not be influenced by the popup.
Thanks
I believe that the Popup control is actually contained within a window, which is why the popup can extend beyond the window bounds in some cases. (It's also why popup transparency is not supported in Silverlight.)
I believe that while the popup control is no longer processing "hits", the container window is, which is why you are losing your button's mouse focus.
I've not tested this, but you might try creating a template for your button and actually declaring the popup as part of the button (rather than below it). This may cause WPF to view the popup control as part of the button and eliminate the problem of losing mouse focus. This works in other scenarios, but I'm not 100% sure how this will work with a Popup.
EDIT: As a side note, the deault WPF tooltip allows you to override the template. I'm not sure what your goals are, but you may find it easier to change the appearance and behavior of the default tooltip than to try to roll your own, as a lot of these sorts of problems have already been solved in the default Tooltip.
I want a button that
Displays an image with NO border, NO background, NO text
If I tab into the imagebutton, THEN it shows the background and border
Also if I hover over it, it shows the background and border
I've searched and I've tried so many different things, but nothing it exactly what I want. I've tried setting various properties on the button to make the background and border transparent, but it still shows up. I've tried a style with a custom control template. I'd rather not have to completely reinvent all the triggers etc to get the button to render on mouse over. The biggest problem with custom control template is that then I loose all existing functionality and I'm basically building a new control from the ground up.
Here is another link that came closest to what I wanted but it doesn't properly work for me.
How do you completely remove the button border in wpf? - BUT.... for some reason the hover effect gets stuck. One I mouse over the image and the button border draws, it stays stuck on until I click somewhere else.
Actually, you will want to override the control template. You're not "losing" any functionality (aside from the UI triggers).
Original/Default Template -- This is a good starting point... copy/paste that into you're XAML (wherever you want to style this button... ie Button resources, UserControl/Window resources, App Resources?). From there make your adjustments.
Another easy way is to use Expression Blend. You can easily create a new template based on the existing template, and the styling/authoring tools it provides are much better than hand-coding XAML (unless you're good at doing that).
As far as displaying an image instead of text, just set the image as the content. A Button is a type of ContentControl which means that it can house any type of content (Object).
I'm getting some inconsistent behavior when I disable certain Button controls in my VS2008 Winforms project.
When I set Enabled = false, the buttons are disabled, but the Text of some (though not all) of the buttons stays black.
I want all buttons to show grey text when disabled - this makes it much easier for the user to see that a button is disabled.
Seems more likely to happen if button is placed in a GroupBox, but I'm not sure this is always the case.
I'm guessing that some combination of properties of the Button, and/or those of the Form or GroupBox containing it are causing this, but I can't see any pattern that makes sense.
Edit: We have our own look and feel, and are setting the BackColor of the containing Form to a different color.
Can anyone explain why this might be happening?
Problem was because the Form's BackColor was set to a different color.
Some Googling revealed that many others have encountered this. The proposed solutions were very complex - subclassing your own button controls and overriding OnPaint, etc.
But it turns out there is a simple fix...
When you add the buttons to the form, the button's BackColor property will be set to the same value as the Form's BackColor, although it will not display that way either at design or run time.
If you set the button's BackColor property to System -> ControlLight, it will fix the problem - the disabled buttons now look disabled.
Note that there's a strange quirk when you reset the BackColor - the UseVisualStyleBackColor property will change from True to False. But this seems to have no effect, and can be changed back to True without affecting the appearance in any way.
I have a button with a transparent background on a wpf window.
Problem is, when I open up another window with a .showdialog the form becomes disabled as does the button, causing the button to go white (and stick out like a sore thumb); the same happens to the listview and textbox controls. Labels and group boxes aren't impacted in this way and remain looking fine.
How do I preserve the transparency color of the button, listview and textboxes when they are disabled?
Thanks, Rob
I'm not sure what your button template looks like, I would recommend posting your XAML. But check out the MSDN Docs on Button Templating
