numericupdown

问题 I am very new to C#, and have a question. I have been able to change the border colors of buttons and such by changing their FlatStyle to "Flat". With the NumericUpDown , I can't change the FlatStyle. I would like to still be able to use the up and down arrows, so just using something else to cover the edges will not work. Here is a simplified version of what I'm doing in my code: using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using

问题 I would like to make WinForms NumericUpDown control non-editable or at least spin control should be disabled. I tried setting the control readonly but using mouse scroll values are changing. Please help me to achieve this. 回答1: Try the following in order to set the numeric up/down as read-only: numericUpDown1.ReadOnly = true; numericUpDown1.Increment = 0; I hope it helps. 回答2: Another alternative is to subclass NumericUpDown and override the DownButton and UpButton methods so they return

问题 Say I have NumericUpDown with Maximum = 99 and Minimum = -99 and initial value = 23 . If user sets focus to this contol and inputs 1 (that would be 123 now) it changes it's value to 99 . How do I keep 23 instead changing value to maximum allowed? I tried to catch KeyDown and KeyPress, but value wasn't changed during this events. Also I tried to implement a workaround explained in this question, but not succeeded. Validating event occurs only on leaving control. I need to simply ignore user

问题 Good day everyone, I'm having a problem passing a numericupdown value into an interger. private void button5_Click(object sender, EventArgs e) { int count = numericUpDown1.Value; updateCount(count); } So, what I want to do it so pass the value of the numericupdown value into integer named count and then pass the value into a method that updates a table in my database. I just started c# lately and cant seem to understand some some documentation. Thank you guys! 回答1: NumericUpDown.Value returns

问题 I have a code where TextBox and NumericUpDown tools are generated dynamically through a foreach loop. Now, I want to be able to get both values in which with each iteration, both their values would be added to the same row in the database. I have the code for getting the NumericUpDown values and I was wondering how can I implement getting the TextBox values too. Code for generating the dynamic NumericUpDown and TextBox t = temp.Split(';'); // e.g. t = Arial;32 int pointX = 70; int pointY = 80

问题 What I want is somewhat similar to what happens in a WinForm designer in Visual Studio, say VS2010. If I place a button and select it and use arrow keys, it will move around by 5 pixels in whatever direction I chose by pressing the right key. Now, if I hold either a Shift or a Ctrl modifier as I do that (forgot which one, sorry), then the button will move only by 1 pixel at a time. I want this to happen with my NumericUpDown control in a C# WinForm app. Let's say a default increment is 100.0,

问题 this is my part of code to parse a NMEA data ( source here Plot chart using values from richTextBox C#) . This function get back latitude from richTextBox, and convert it to decimal notation. I need it, to plot charateristic from 4 another GPS module (to compare accuracy all four GPS). This is my problem. I want to use a "numericUpDown" to change Math.Round (below I have value - 11). I cant get inside Tuple because I have error (I tried to do something, but it didnt work). Can anybody know,
