When set a TooltipText on a control, and the tooltip text will be shown when user move mouse on the control. Tooltip will detect MouseEnter or MouseLeave or anything for this purpose?
I want to know how does a Tooltip show Popup on a control?
Assume that I have a user control with name 'UserControlX'. On UserControlX, I put a button and set Dock property to Fill. I add a UserControlX on Form1, add a ToolTip and set a text to this usercontrol. ToolTip will be not shown when user move mouse on control because user is moving mouse on usercontrol's button, not usercontrol, so the tooltip will never show.
Please help me how to solve this problem so that when move mouse on UserControlX, the tooltip will be shown. Thanks.
I believe the tooltip displaying on mouse-over is defined within the control's default template. if you view the default template you will likely see a reference to a tooltip in there. If you go further and view the Tooltip's default template, you will see how it is composed as well as what events it listens to.
To answer your question, you could do what Adrian suggests and put the tooltip on the button as well as the parent control.
If you have time to mess around a bit, you COULD try to see if there is a tooltip displayed event or something to that effect for the button, and then simply invoke the parent control's tooltip manually. It could be considered a hack, but worth a try, maybe.

I have a simple ToolStrip with buttons in it which contain images and text. When I go over that button it changes appearance (same when it gets clicked). How can I customize this so that it stays highlighted when clicked? I have to do this over a tabControl so that it stays highlighted when the tab is entered and gets back to its normal appearance when leaving the tab. Which methods do I have to override?
Thank you!
just set ToolStripButton.CheckOnClick property to true from design time. So it will stay highlited when clicked.
About the other requirement set ToolStripButton.Checked to true on entring the tab control, and set it to false on leaving the tab control.
For entering and leaving you may use Control.Leave & Control.Enter events of tabpage/tabcontrol.
Let me know incase of any issues
I have a label that I need to stay on top of my TabControl as I switch from tab to tab. I have tried calling the Label's BrintToFront method in the SelectedIndexChanged Event of the Tab Control but this has no effect. I also simply tried right clicking my label in design view and selecting "Bring to Front" but again, this had no effect.
When I switch to my second tab it drops behind the TabControl however, when I go back to my first tab it is in front again.
I placed the label itself on the Form rather than on the TabControl.
I am working in C#. Any ideas would be greatly appreciated. Thanks.
You should make sure that your label is not located inside a specific tab. To verify this you need to look at the nesting inside the 'document outline' (ctl+alt+T)
If it is I recommend;
dragging it just outside the tab control (you can also use the document outline).
then 'bring it to the front'.
and then use the arrow keys, or location property, to move it back into position.
How to focus an image in Silverlight?
For example: imagine that when my page loads, It will focus on a texbox, so I don't have to click in there to control. I want the same with image control.
There is no way for an Image to acquire input focus directly.
Input focus is supported only on Controls and its descendants which have the properties IsEnabled and IsTabStop set to true. Image is derived from FrameworkElement, not from Control, so it's not technically a control.
You could create a UserControl that contains the image and then call .Focus() on the container control.
It sounds like you want to make a button of the image and than set the button with the default focus.

I have a custom control and I would like it to act like a button i.e. when you hover over it changes a little so it seems "clickable" to the user
I actually acheived this using the MouseEnter and MouseLeave events and changing the gradient but...
is there a way to apply a style to the user control and say something like TargetType="button" so that it "acts" like a button automatically?
I feel the way i'm doing it is not the best way
As sniper says, you can set a Controltemplate for each state.
Alternatively, you can completely replace a control's visual tree with anything you want - while still keeping the control behavior intact. Check out this post by ScottGu on the topic
In Expression Blend 3, you can edit the different states (Normal, Hover, pressed, selected etc), of any control how you need it. just select your control and click Edit copy template
Add border object and sets its visibility on mousehover and leave event on the control (This will look like a flat\popup button). Additionally set the control's cursor to hand.
You can derive your control from ButtonBase, just like Button, HyperlinkButton, Checkbox, etc.
I am adding a label to a form dynamically, then dynamically adding a ContextMenuStrip control. Whether I use the label.ContextMenuStrip property to connect them, or add the event handler to the label manually to have it respond to the right-click and show the context menu, I get odd behavior:
1) The menu does not appear next to the mouse pointer, it is offset down and to the right. It appears that it is related to the position of the label in it's parent control (a picture control), rather than the form.
2) The menu does not disappear when I click on something other than the menu.
Any ideas what I am missing here?
Thanks,
Andy
I worked it out. First off, I was adding the control to the label control collection, changing it to the the form collection corrected the positioning problem. I never did figure out why the menu would not close.
Ultimately I restructured things by adding a static instance of the menu to the form, then just connected the label.ContextMenuStrip property to that stastic instance. All is well with that approach.
I used the tag of the label control to identify it to the click event handler.
