every thread I've seen is trying to figure out something more complex. as a project for school I am making a grocery list form. I don't know how to work with the numericUpDown control. The form requests this information:
item: (textBox as string)
qty: (this is the numericUpDown)
size: (comboBox: can select from lb, gal, oz, each,.....etc)

View 5 RepliesI'am using the NumericUpDown_Validating event to cancel mouse clicks on the up and down arrows of the control.The idea is that the NumericUpDown control will stop incrementing when the base of a form reaches the bottom of the screen. That works, however the textvalue keeps incrementing. Why does the text keep incrementing and how do I stop it?

View 2 RepliesSo I'm currently working on a control that acts as a HTML editor. One of the thing that I need to do is insert tables, in order to do that I needed to provide the user with some options first. When thinking of the design for this, I decided to go with the form layout that Word 2003 uses;
Now as you may notice the third NumericUpDown control has "Auto" written in it. This is one of the values the other values include;

how I might be able to get my NumericUpDown control (or another control) to display those non-numeric options.
I'm using a NumericUpDown control with a Minimum set to 10 (using for font size setting). When it is changed, it is bound to an Application setting and saved. On Form Load, I am attempting to set the value of the NumericUpDown control to the value stored in that setting (14 for example). No matter what though, it doesn't use the setting's value, it uses the value of the "Minimum" property of the NumericUpDown control.
View 10 Repliesi have put numericupdown in one column of datagidview. that column represent the time in format(HH:MM). i want to change MM and HH separately with the help of numericupdown. How can i change value of MM and HH with the help of Numericupdown in datagrid view.
View 2 RepliesI want to set the TextChanged event in NumericUpDown box,so that when you press a key, it instantly fires the textchanged event.The default ValueChanged event of the NumericUpDown box does not instantly fire the ValueChanged event. You need to first press the Enter key after you enter a number.And I read somewhere that NumericUpDown box also has a TextChanged event.How do I set the TextChanged event in the NumericUpDown box?
View 2 RepliesI have not been able to find a way to get the datetimepicker with ShowUpDown= True and custome format set to h:m tt to increment in 15 min intervals. I have been able to set it when the form is loaded to the nearest 15 min increment. But I need it to increment in 15 minutes units.
This can be down with the NumericUpDown control, but I need two of them one for the hour and one for the minutes and set it's Increment property to 15. Again I can set it to adjust to correct hour and the nearest 15 min. And of course I have to watch and when I go over 60 reset to zero and increment the hour control.
The users will be burly oil field workers using a Panasonic Tablet PC with a stylus in the field. It seems that it would be easier if I could increment the datetimepicker in 15 intervals.
I have done some code so that when you choose a number from the numeriupdown it will look at the if statement and put the age into a category. the thing is the number in the updown doesnt go into the right category?

View 3 RepliesI have my numeric up and down control set up but there is one problem. When i run the application, there is an IBeam in the value box. I have got my alphabet and arrow keys mapped to other things so when i press them windows makes the annoying beep noise. How can i get rid of the IBeam from this control permanently? I have tried the read only setting but the beam is still there.
View 1 RepliesAs part of a program that I am composing, the user needs to enter a value by way of a NumericUpDown control on one particular form. Once this and other criteria have been evaluated, the program will then move to the next "step" of the program. If they use the spinner built into the NumericUpDown control, the event is fired on every change and that's all well and good, but if they double-click the value in the control then type the value in manually, it doesn't fire until the control no longer has focus. I can't depend that this might be the case however. Using the "KeyPress" event, I can in fact know when the control has focus and the user has typed but what I cannot seem to get it to do is to get the control to "read" these keystrokes as values until the control loses focus.
View 3 RepliesI would like a program that will use a NumericUpDown button:
-when the up arrow is clicked, the number in the NumericUpDown box will increment by 2 -when the down arrow is clicked, the number in the NumericUpDown box will decrement by -2
I got the button inserted and double clicked on it to get the NumericUpDown1_ValueChanged but am stuck there. I looked thru the MSDN site
I have a form with 84 NumericUpDown controls. How can I load each value into an array. E.G. Aryhours(1) = NumericUpDown1, AryHours(2) = NumericUpDown2..
View 3 RepliesI have eight NumericUpDown controls in my form, I call them NumericUpDown_1 thru NumericUpdown 8. I first noticed when I set a breakpoint in say NumericUpDown_1 routine and have code inside this routine to manipulate say NumericUpdown_6's value, the code would immediate jump to NumericUpdown_6 routine because the value changed. This makes sense since the handler fires due to the default handler - numericUpDown_valuechanges. But I do not want this to happen so I removed the handlers for all NumericUpdownX routines, one thru eight and instead I use "addhandler" and "removehandler" statements inside the individual routines to "mask off" this problem every time I change a numericUpDown.Value that is not in it's own routine.
My problem is this does not work. What I found is if I use removehandler numericUPDown_x.valuechange addressof numericUpdown_valuechange statement the coding would work however when I'm done in that routine I follow up with addhandler numericUpDown... statement and I'm back to the same problem. A different numericUpDown routine will fire because I changed it's value in another routine but I had the handler removed before I changed it's value so I don't understand. It's almost like it remembered that it's value changed as soon as I turned back on the handler using addhandler. I'm working with Visual Basic 2010.
When I press the Enter key in NumericUpDown box, it makes a beep sound.Is there a way to mute it?Also, when performing calculations, the value entered in NumericUpDown box doesn't show instantly in TextBox1,
View 5 RepliesMy form contains several NumericUpDown controls. These controls show different amount of decimal places. Later in my code I put the different NumericUpDown.Value's in a string array arrStr() like so:
arrStr(1) = NumericUpDown1.Value
arrStr(2) = NumericUpDown2.Value
arrStr(3) = NumericUpDown3.Value
Then I print the array with the File.WriteAllLines function to a text file.
If for example NumericUpDown1.Value = 1.00, NumericUpDown2.Value = 2.30 and NumericUpDown3.Value = 2.124 the file has the following values in it:
1
2.3
2.124
[Code].....
I have tried Format which works, but that formatting method is not convenient as the amount of decimal places is already set for each NumericUpDown. It would be annoying to do the work again, but now with Format.
For a NumericUpDown control in VB 2005, how do I distinguish between a change to the numeric value made by the user (by changing the text or clicking the up or down arrows), and a change made internally by my code? The "Scroll" event works for user changes to the TrackBar control, but not for me on the UpDown control, and the ValueChanged event doesn't distinguish the source of the change.
