We Keep Coding

In C#, won't drag enter, drag drop and drag leave get triggered when a control is dragged and dropped over other?

In C#, when I drop a file on panel, drag events are triggered automatically. But if I drag a control like Button on another control like Button, no drag event gets triggered. Do we need to use mouse down and mouse down for this?

WinForms pass through clicks to controls below another

I have a following form in WinForms as a prototype for a game:
GestureControl is a transparent Control that handles its MouseDown and MouseUp events to allow for swiping gestures. Then there are SquareControls (game pieces) that should be clickable as well.
I'm not sure how to arrange these controls so both
SquareControl will receive Click event
GestureControl will receive MouseDown and MouseUp events
I know I could add a Click Gesture to my GestureControl (when the distance between mouse down and mouse up is not far away), pass it to parent and invoke the same event handler as if the corresponding SquareControl was clicked, but this seems hackish.

WPF Touch up event in Microsoft surface still calls even I dragg my finger out of the area

I am writing an event for a textBox_Touch_up. And I want if user Touch Up on the text box then fire this event but if user dragged his finger somewhere out of the textbox and then touch up then this event should not be called. Is there any other event with which I can do it or I Have to play with it ?

The touch_up Event does not provide similar functionality for Textboxes because Textboxes contain text. So I used a flat button and it works for me as it does not fire the event when i drag my finger out of it.

Trigger MouseMove Event for Specific Number of Time

I have a custom CustomToolStripMenuItem which is derived from ToolStripMenuItem Class. In that custom class 'CustomToolStripMenuItem', I override OnPaint(), OnMouseMove() and OnMouseDown() Events.
Here, I want to add a rectangle to show on each sub menu to delete that menu item from customized tool strip menu items. When user move mouse to rectangle area, it will change back color which shows that user want to delete that item. I add these menus by reading an xml file.
The main problem here is that, when I move the mouse from one menu item to other quickly, previous item also shown as selected. How can I ensure that when mouse move to other menu item, previous selection should erase.
What I guess, I need to repeat that mouse move event for specific times (total items in xml file), but How can I do this with events of mouse ???
Any Help ?

You can also use MouseLeave event with current events, if fast mouse move bypasses your current MouseMove event!

Change mouse pointer on component border

I'm trying to change the mouse pointer as it moves over the outer borders of a component. Sort of the same way it changes when moved over the borders of a resizable form. Any ideas?

Controls have events like
MouseEnter
MouseLeave
MouseHover
and so on. Use one of them
