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：
//
// BtnNum1
//
this.BtnNum1.Dock = System.Windows.Forms.DockStyle.Fill;
, );
this.BtnNum1.Name = "BtnNum1";
, );
)));
)));
;
";
this.BtnNum1.Click += new System.EventHandler(this.BtnNum_Click);
//
// BtnNum2
//
this.BtnNum2.Dock = System.Windows.Forms.DockStyle.Fill;
, );
this.BtnNum2.Name = "BtnNum2";
, );
)));
)));
;
";
this.BtnNum2.Click += new System.EventHandler(this.BtnNum_Click);
//
// BtnNum3
//
this.BtnNum3.Dock = System.Windows.Forms.DockStyle.Fill;
, );
this.BtnNum3.Name = "BtnNum3";
, );
)));
)));
;
";
this.BtnNum3.Click += new System.EventHandler(this.BtnNum_Click);
//
// BtnNum4
//
this.BtnNum4.Dock = System.Windows.Forms.DockStyle.Fill;
, );
this.BtnNum4.Name = "BtnNum4";
, );
)));
)));
;
";
this.BtnNum4.Click += new System.EventHandler(this.BtnNum_Click);
//
// BtnNum5
//
this.BtnNum5.Dock = System.Windows.Forms.DockStyle.Fill;
, );
this.BtnNum5.Name = "BtnNum5";
, );
)));
)));
;
";
this.BtnNum5.Click += new System.EventHandler(this.BtnNum_Click);
//
// BtnNum6
//
this.BtnNum6.Dock = System.Windows.Forms.DockStyle.Fill;
, );
this.BtnNum6.Name = "BtnNum6";
, );
)));
)));
;
";
this.BtnNum6.Click += new System.EventHandler(this.BtnNum_Click);
//
// BtnNum7
//
this.BtnNum7.Dock = System.Windows.Forms.DockStyle.Fill;
, );
this.BtnNum7.Name = "BtnNum7";
, );
)));
)));
;
";
this.BtnNum7.Click += new System.EventHandler(this.BtnNum_Click);
//
// BtnNum8
//
this.BtnNum8.Dock = System.Windows.Forms.DockStyle.Fill;
, );
this.BtnNum8.Name = "BtnNum8";
, );
)));
)));
;
";
this.BtnNum8.Click += new System.EventHandler(this.BtnNum_Click);
//
// BtnNum9
//
this.BtnNum9.Dock = System.Windows.Forms.DockStyle.Fill;
, );
this.BtnNum9.Name = "BtnNum9";
, );
)));
)));
;
";
this.BtnNum9.Click += new System.EventHandler(this.BtnNum_Click);
//
// BtnNum0
//
);
this.BtnNum0.Dock = System.Windows.Forms.DockStyle.Fill;
, );
this.BtnNum0.Name = "BtnNum0";
, );
)));
)));
;
";
this.BtnNum0.Click += new System.EventHandler(this.BtnNum_Click);
//
// BtnNumDel
//
this.BtnNumDel.Dock = System.Windows.Forms.DockStyle.Fill;
, );
this.BtnNumDel.Name = "BtnNumDel";
, );
)));
)));
;
this.BtnNumDel.Values.Text = "Del";
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：
#region 小键盘按钮事件
/// <summary>
/// 触摸小键盘
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void BtnNum_Click(object sender, EventArgs e)
{
KryptonButton btn = (KryptonButton)sender;
try
{
CurrentTextEdit.Text += btn.Text;
}
catch
{
}
}
/// <summary>
/// 进入控件发生事件
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void textEdit_Enter(object sender, EventArgs e)
{
CurrentTextEdit = (KryptonTextBox)sender;
}
/// <summary>
/// Del按钮
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void BtnNumDel_Click(object sender, EventArgs e)
{
CurrentTextEdit.Text = string.Empty;
}
#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：
<Button Content="1" Style="{DynamicResource BtnS1}" FontFamily="KaiTi_GB2312" FontWeight="Bold" FontSize="29.333" Margin="5" Click="BtnKeyBoard_Click"/>
<Button Content="2" Style="{DynamicResource BtnS1}" FontFamily="KaiTi_GB2312" FontWeight="Bold" FontSize="29.333" Grid.Column="1" Margin="5" Click="BtnKeyBoard_Click"/>
<Button Content="3" Style="{DynamicResource BtnS1}" FontFamily="KaiTi_GB2312" FontWeight="Bold" FontSize="29.333" Grid.Column="2" Margin="5" Click="BtnKeyBoard_Click"/>
<Button Content="4" Style="{DynamicResource BtnS1}" FontFamily="KaiTi_GB2312" FontWeight="Bold" FontSize="29.333" Grid.Row="1" Margin="5" Click="BtnKeyBoard_Click"/>
<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"/>
<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"/>
<Button Content="7" Style="{DynamicResource BtnS1}" FontFamily="KaiTi_GB2312" FontWeight="Bold" FontSize="29.333" Grid.Row="2" Margin="5" Click="BtnKeyBoard_Click"/>
<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"/>
<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"/>
<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"/>
<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：
#region 小键盘事件
/// <summary>
/// 触摸小键盘
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void BtnKeyBoard_Click(object sender, RoutedEventArgs e)
{
///获取父类中的Btn
Button btn = (Button)e.OriginalSource;
if (pickbox == true)
{
try
{
TextBoxEdit.Text += btn.Content;
}
catch
{
}
}
else if (pickbox == false)
{
try
{
PasswordBoxEdit.Password += btn.Content;
}
catch
{
}
}
}
/// <summary>
/// 删除输入
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void Del_Click(object sender, EventArgs e)
{
if (pickbox == true)
{
TextBoxEdit.Text = string.Empty;
}
else if (pickbox == false)
{
PasswordBoxEdit.Password =string.Empty;
}
}
/// <summary>
/// 用户编号Focus
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void TextBoxEdit_Focus(object sender, EventArgs e)
{
TextBoxEdit = (TextBox)sender;
pickbox = true;
}
/// <summary>
/// 用户密码Focus
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void PasswordBoxEdit_Focus(object sender, EventArgs e)
{
PasswordBoxEdit = (PasswordBox)sender;
pickbox = false;
}
#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。
