NumericUpDown differentiate up and down
(2 answers)
Closed 9 months ago.
Is there a way to detect with the Numeric Up-down control to see if the Up or Down button is pressed without coding?
I know I could keep track of the current value and write some code in the method ValueChanged. I was just thinking maybe there is an easier/shorter way to do this
If you want to track specifically the buttons being used and not the value being changed directly you can create your own UserControl that inherits from NumericUpDown and override the UpButton() and DownButton() methods. Otherwise if you want to track all value changes, using the ValueChanged event is the best way to cover all ways of changing the value, including programatically.

How to make an ownerdraw Trackbar in WinForms

Closed 6 years ago.
I was planning on creating a custom TrackBar class that implements from TrackBar. I want it to look/feel EXACTLY the same, other than a display on the value just to the side of the track itself.
I've been seeing that you can either let the OS draw the control, or allow the user draw it, but then the user must draw EVERYTHING. Is there a way for me to allow the OS draw the control, and then let me draw the value?
EDIT:
The key I want to emphasize is, I want to only add the drawing the value, rather than drawing the whole thing myself.

What's the difference between a button with IsDefault and IsDefaulted?
(3 answers)
Closed 8 years ago.
Can you please explain me what do these two properties?
Button.IsDefault and Button.IsDefaulted
I tried to run the example on MSDN but it works.
http://msdn.microsoft.com/en-us/library/system.windows.controls.button.isdefault(v=vs.110).aspx
I should create a method?
Can you make me two simple example please?
IsDefault can be got or set, to make the button the default when enter is pressed.
IsDefaulted is the ReadOnly property that shows if the button is default. This is used in the code behind.
For example, if you want your button to be the default button for the form, use
<Button Name="btn_whatever" IsDefault="True"/>
Then you can do in the C#
if(btn_whatever.IsDefaulted)
//do something
or
if(btn_whatever.IsDefault)
//do something

Is it possible to check a form for any empty text boxes rather than having to put a check on each individual text box with an if? Any help would be much appreciated.
I'm not that familiar with WPF, but you might try to get a list of the child-elements in a form, and for each, check if they are of type Textbox. If so, perform your validation.

Everything is possible, but the question is what You really want to achieve by this strange behavior ?
What's wrong with standard usage of the OK button ? Where You pick the path and do what You want to.
