I have an slider control in my application and an image control. When the slider value is going up, the image is zoomed in and vice versa.
In addtion i have a zoom-in and a zoom-out button. the zoom-in button will increase the slider value by one smallchange and the zoom-out will decrease it.
What i want: while the zoom-in (and out) button is pressed i want to slider to keep increasing(performin a zoom in) and not just one time.
In other words, as long as the left button is pressed, i want to keep performing the mousebuttonpressed on the button until the mousebutton is released.
Oh, by the way, im using Silverlight 3.
Thanks.
You can use the RepeatButton class to do this. It raises it's click event repeatedly while held down, much like the thumb of a scrollbar or an up/down spinner.

I'm using a horizontal slider in WPF, but would like to also perform some action if the mouse is moved vertically (like change the brightness of some control).
I tried responding to MouseMove, but I don't get an update when dragging the slider, if the mouse moves purely vertically - my function only gets called when the slider actually moves.
You could attach a handler to the slider's PreviewMouseMove event.
I'm trying to write a WinForms program that will capture mouse coordinates upon pressing and (more importantly) releasing the middle mouse button.
My form has topmost set to true (so that text in it can always be visible even when it doesn't have focus).
What I'm aiming for is being able to hover the mouse over a game window after my program starts, hit the middle mouse button, and have it record the mouse position for later use.
I can get it to detect when the middle mouse button is clicked inside the form using the MouseUp event (bound to the form itself) but have no clue what I need to do to have it detect when the mid mouse is clicked outside my form.
Thanks for any help guys.
I believe what you are after are called low level hooks. A quick google brings up this: Erroneous Mouse Coordinates Returned from Low Level Mouse Hook C#
A microsoft example of how to do can be found here: http://support.microsoft.com/kb/318804
Is there any way to animate or fade a LibraryBar? I want a Library Bar which isnt shown to 100 percent on normal use. I want a little bar at the bottom (maybe a part of the LibrarayBar). When the mouse or finger click on the bar (little part of the LibrarayBar) the whole bar should appear with a slow fade in or animation.
Anybody of you know how to this?
Sry fpr my English......
You could write 2 routed event handlers for GetFocus and LostFocus events by declaring them as attributes of GetFocusEvent and LostFocusEvent (or MouseEnter and MouseLeave) depending on whether you want the glowing/dimming to happen with an explicit click or reactive to just "hovering".
These handlers would alter the OpacityProperty property.
To start "dimmed", you can adjust an initial value for the Opacity propert
In some programs, for example, Microsoft Office Excel, when you’re at the end of the document being edited and then press a right or down arrow of the scrollbars, then, you scroll further and the edited area will grow, producing more space for entering data. Can this functionality be implemented in WPF?
I tried using ScrollBar instead of ScrollView to get more control, but didn’t succeed. If the scroll bar is at its maximum value, pressing the right or down (depending on the orientation) button of it doesn’t fire the scroll event.
I would like to know if there is a way to resize a button Width using the mouse, like when you are in the design mode, I'd like to change the cursor to the resize cursor when the mouse pass over the edge of the button, and with a sutained click resize the button.
thanks !!
You should look into using Adorners for this. Here is an article on Code Project that describes how to "drag, resize and rotate elements on a Canvas", with and without Adorners: WPF Diagram Designer: Part 1
