textBox用法总结:
1 去掉边框 【注:this = textBox】 this.BorderStyle = System.Windows.Forms.BorderStyle.None;
2 设置字体 this.Font = new System.Drawing.Font(this.Font.Name, 11);
3 设置光标 this.Focus();//光标移动到当前textBox中 this.SelectAll(); //选中所有内容 this.SelectionStart = this.Text.Length;///设置光标在末尾
4 设置大小 this.Size = new System.Drawing.Size(30, 25);
5 设置最大字符个数 this.MaxLength = 3; //最大为3个
6 添加控件,设置控件位置 Label lb = new Label(); this.Controls.Add(lb);//添加一个Label lb.Location = new System.Drawing.Point(10,10);
7 设置字体居中 this.TextAlign = HorizontalAlignment.Center;
8 控制输入内容 --- 重写textBox事件 protected override void OnKeyPress(KeyPressEventArgs e) { //阻止键盘输入e.KeyChar.ToString()按键字符 e.Handled = true; if ((e.KeyChar >= '0' && e.KeyChar <= '9') || (e.KeyChar == (char)8)) { //只能输入0 -9 e.Handled = false; return ; } }
