WinForm数字小键盘--WPF数字小键盘
模仿原本的WinForm触摸屏小键盘制作WPF触摸屏小键盘
原WinForm触摸屏小键盘样式（WinForm采用Krypton系列控件）如下图：
Designer代码如下：
1 // 2 // BtnNum1 3 // 4 this.BtnNum1.Dock = System.Windows.Forms.DockStyle.Fill; 5 this.BtnNum1.Location = new System.Drawing.Point(3, 3); 6 this.BtnNum1.Name = "BtnNum1"; 7 this.BtnNum1.Size = new System.Drawing.Size(125, 62);

10 this.BtnNum1.TabIndex = 0; 11 this.BtnNum1.Values.Text = "1"; 12 this.BtnNum1.Click += new System.EventHandler(this.BtnNum_Click); 13 // 14 // BtnNum2 15 // 16 this.BtnNum2.Dock = System.Windows.Forms.DockStyle.Fill;

120 this.BtnNum0.Values.Text = "0"; 121 this.BtnNum0.Click += new System.EventHandler(this.BtnNum_Click); 122 // 123 // BtnNumDel 124 // 125 this.BtnNumDel.Dock = System.Windows.Forms.DockStyle.Fill; 126 this.BtnNumDel.Location = new System.Drawing.Point(266, 207); 127 this.BtnNumDel.Name = "BtnNumDel"; 128 this.BtnNumDel.Size = new System.Drawing.Size(127, 64); 129 this.BtnNumDel.StateCommon.Content.ShortText.Font = new System.Drawing.Font("隶书", 24F, System.Drawing.FontStyle.Bold, System.Drawing.GraphicsUnit.Point, ((byte)(134)));

132 this.BtnNumDel.Values.Text = "Del"; 133 this.BtnNumDel.Click += new System.EventHandler(this.BtnNumDel_Click);
所有按钮的点击事件为BtnNumDel_Click，功能实现的代码如下：
1 #region 小键盘按钮事件 2 /// <summary> 3 /// 触摸小键盘 4 /// </summary> 5 /// <param name="sender"></param> 6 /// <param name="e"></param> 7 private void BtnNum_Click(object sender, EventArgs e) 8 { 9 KryptonButton btn = (KryptonButton)sender; 10 try 11 { 12 CurrentTextEdit.Text += btn.Text; 13 } 14 catch 15 { 16 17 } 18 } 19 /// <summary> 20 /// 进入控件发生事件 21 /// </summary> 22 /// <param name="sender"></param> 23 /// <param name="e"></param> 24 private void textEdit_Enter(object sender, EventArgs e) 25 { 26 CurrentTextEdit = (KryptonTextBox)sender; 27 } 28 /// <summary> 29 /// Del按钮 30 /// </summary> 31 /// <param name="sender"></param> 32 /// <param name="e"></param> 33 private void BtnNumDel_Click(object sender, EventArgs e) 34 { 35 CurrentTextEdit.Text = string.Empty; 36 } 37 38 #endregion
对于简易的小键盘来说，个人觉得这么写还算简洁。只要把想输入的TextBox的Enter事件设置为textEdit_Enter即可实现输入。
由于WPF初学，所以没有想到更简单的方法，而且WPF与WinForm很相似，所以仿照着写了一个。
XAML代码如下：
1 <Button Content="1" Style="{DynamicResource BtnS1}" FontFamily="KaiTi_GB2312" FontWeight="Bold" FontSize="29.333" Margin="5" Click="BtnKeyBoard_Click"/> 2 <Button Content="2" Style="{DynamicResource BtnS1}" FontFamily="KaiTi_GB2312" FontWeight="Bold" FontSize="29.333" Grid.Column="1" Margin="5" Click="BtnKeyBoard_Click"/> 3 <Button Content="3" Style="{DynamicResource BtnS1}" FontFamily="KaiTi_GB2312" FontWeight="Bold" FontSize="29.333" Grid.Column="2" Margin="5" Click="BtnKeyBoard_Click"/> 4 <Button Content="4" Style="{DynamicResource BtnS1}" FontFamily="KaiTi_GB2312" FontWeight="Bold" FontSize="29.333" Grid.Row="1" Margin="5" Click="BtnKeyBoard_Click"/> 5 <Button Content="5" Style="{DynamicResource BtnS1}" FontFamily="KaiTi_GB2312" FontWeight="Bold" FontSize="29.333" Grid.Column="1" Grid.Row="1" Margin="5" Click="BtnKeyBoard_Click"/> 6 <Button Content="6" Style="{DynamicResource BtnS1}" FontFamily="KaiTi_GB2312" FontWeight="Bold" FontSize="29.333" Grid.Column="2" Grid.Row="1" Margin="5" Click="BtnKeyBoard_Click"/> 7 <Button Content="7" Style="{DynamicResource BtnS1}" FontFamily="KaiTi_GB2312" FontWeight="Bold" FontSize="29.333" Grid.Row="2" Margin="5" Click="BtnKeyBoard_Click"/> 8 <Button Content="8" Style="{DynamicResource BtnS1}" FontFamily="KaiTi_GB2312" FontWeight="Bold" FontSize="29.333" Grid.Column="1" Grid.Row="2" Margin="5" Click="BtnKeyBoard_Click"/> 9 <Button Content="9" Style="{DynamicResource BtnS1}" FontFamily="KaiTi_GB2312" FontWeight="Bold" FontSize="29.333" Grid.Column="2" Grid.Row="2" Margin="5" Click="BtnKeyBoard_Click"/> 10 <Button Content="0" Style="{DynamicResource BtnS1}" FontFamily="KaiTi_GB2312" FontWeight="Bold" FontSize="29.333" Grid.Row="3" Grid.ColumnSpan="2" Margin="5" Click="BtnKeyBoard_Click"/> 11 <Button Content="DEL" Style="{DynamicResource BtnS1}" FontFamily="KaiTi_GB2312" FontWeight="Bold" FontSize="29.333" Grid.Column="2" Grid.Row="3" Margin="5" Click="Del_Click"/>
这里WPF略有不同的是，TextBox并没有Enter事件，尝试多次使用GotFocus事件代替，代码如下：
1 #region 小键盘事件 2 /// <summary> 3 /// 触摸小键盘 4 /// </summary> 5 /// <param name="sender"></param> 6 /// <param name="e"></param> 7 private void BtnKeyBoard_Click(object sender, RoutedEventArgs e) 8 { 9 ///获取父类中的Btn 10 Button btn = (Button)e.OriginalSource; 11 if (pickbox == true) 12 { 13 try 14 { 15 TextBoxEdit.Text += btn.Content; 16 } 17 catch 18 { 19 20 } 21 } 22 else if (pickbox == false) 23 { 24 try 25 { 26 PasswordBoxEdit.Password += btn.Content; 27 } 28 catch 29 { 30 31 } 32 } 33 } 34 /// <summary> 35 /// 删除输入 36 /// </summary> 37 /// <param name="sender"></param> 38 /// <param name="e"></param> 39 private void Del_Click(object sender, EventArgs e) 40 { 41 if (pickbox == true) 42 { 43 TextBoxEdit.Text = string.Empty; 44 } 45 else if (pickbox == false) 46 { 47 PasswordBoxEdit.Password =string.Empty; 48 } 49 } 50 /// <summary> 51 /// 用户编号Focus 52 /// </summary> 53 /// <param name="sender"></param> 54 /// <param name="e"></param> 55 private void TextBoxEdit_Focus(object sender, EventArgs e) 56 { 57 TextBoxEdit = (TextBox)sender; 58 pickbox = true; 59 } 60 /// <summary> 61 /// 用户密码Focus 62 /// </summary> 63 /// <param name="sender"></param> 64 /// <param name="e"></param> 65 private void PasswordBoxEdit_Focus(object sender, EventArgs e) 66 { 67 PasswordBoxEdit = (PasswordBox)sender; 68 pickbox = false; 69 } 70 #endregion
而且WPF的TextBox控件与PasswordBox控件不同，无奈之下还加了一个变量pickbox用来区分。
