当用户输入文本框中的文本更改时，如何更新表单上的文本框 [英] How can I update text box's on my form when text changes in the user input text box's
问题描述
我是新学习C＃而且我正在重新创建我很久以前制作的电子表格程序，它模拟了我曾经玩过的游戏中技能系统的运作方式（Anarchy Online）。
Hi, I am new learning C# and i am recreating my spreadsheet program i made a long time ago which emulates how the skills system works in a game i used to play (Anarchy Online).
一个按钮用于执行计算并将值发送到文本框
A button is used to perform the calculations and send the values to the text boxs
四个文本框是用户输入和另外七个文本框文本框用于显示正在计算的数字。
Four text boxs are user input and seven other text boxs are used to display a number that are being calculated among eachother.
我只想执行计算并在用户键入任何用户输入文本时发送到文本框盒子所以我可以摆脱计算按钮
I just want to perform the calculations and send to the text boxs when the user types in ANY of the user input text boxs so i can get rid the the calculate button
到目前为止这个代码：

using System.Windows.Forms;

public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
// %-Key used to determin how much points trickledown to the skill that is based on points
// spent on one or more ability that it is dependant on - in this case i use one skill
// that is dependant on one ability therefore i only need one percentKey for now
private double percentKey100 = 0.25;
// these two are user input
public double nakStm; // B-ability
public double addedStm; // O-ability
private double startingPointsAbilities = 6; // point character starts with
private double startingPointsSkills = 4; // points character starts with
private double spentIPStm; // F-ability = nakAbillity - startingAbilityPoints
// these two are user input also
public double nakBdyDev; // B-skills
public double addedBdyDev; // O-skills
private double totalStm; // G-ability = IP Spent + startingAbilityPoints + addedAbility
// C-nakTrickledown and Collumn D-totalTrickledown
private double nakTrickleBdyDev; // C-nakTrickle = percentKey100 * nakAbility
private double totalTrickleBdyDev; // D-totalTrickle = percentKey100 * totalAbility
private double trickleAddedAbiOnlyBdyDev; // E-addedTrickle = D-totalTrickle - C-nakTrickle
private double totalSpentIPBdyDev; // F-skill = B-skill - C-nakTrickle - startingSkill
private double totalBdyDev; // G-Skill = B-skill + E-addedTrickle + O-skill
private void button1_Click(object sender, EventArgs e)
{
// These textbox's have to be set to txtbox's and converted to double first so that
// the following formulas can use them and not get a conversion error.
nakStm = Convert.ToDouble(nakStmTxtBox.Text); // B-ability
addedStm = Convert.ToDouble(addedStmTxtBox.Text); // O-ability
nakBdyDev = Convert.ToDouble(nakBdyDevTxtBox.Text); // B-skills
addedBdyDev = Convert.ToDouble(addedBdyDevTxtBox.Text); // O-skills
// perform nessary calculation...
spentIPStm = nakStm - startingPointsAbilities; // F-ability
totalStm = spentIPStm + startingPointsAbilities + addedStm; // G-ability
// trickledown calculation
nakTrickleBdyDev = Math.Ceiling(percentKey100 * nakStm); // C-nakTrickle
totalTrickleBdyDev = Math.Ceiling(percentKey100 * totalStm); // D-addedTrickle
trickleAddedAbiOnlyBdyDev = totalTrickleBdyDev - nakTrickleBdyDev; // E-Skill
// Spent IP Points - for viewing only not used for other calculations
totalSpentIPBdyDev = nakBdyDev - nakTrickleBdyDev - startingPointsSkills; // F-Skill
// total skill after trickledown added in
totalBdyDev = nakBdyDev + trickleAddedAbiOnlyBdyDev + addedBdyDev; // G-Skill
// show values in text box's
spentIPStmTxtBox.Text = spentIPStm.ToString(); // F-ability
totalStmTxtBox.Text = totalStm.ToString(); // G-ability
nakTrickleBdyDevTxtBox.Text = nakTrickleBdyDev.ToString(); // C-nakTrickle
totalTrickleBdyDevTxtBox.Text = totalTrickleBdyDev.ToString(); // D-totalTrickle
trickleAddedAbiOnlyBdyDevTxtBox.Text = trickleAddedAbiOnlyBdyDev.ToString(); // E-addedTrickle
totalSpentIPBdyDevTxtBox.Text = totalSpentIPBdyDev.ToString(); // F-skill
totalBdyDevTxtBox.Text = totalBdyDev.ToString(); // G-skill
// Properties.Settings.Default.Save();
}
}

推荐答案
您可以双击表单设计器上的文本框控件，然后VS将放置 代码中的Changed事件的占位符代码，您可以在其中开始编码事件。
You can double-click the textbox control on the form designer, and VS will put the place holder code for the Changed event in the code for you where you can start coding the event.
