[英]DataGridView TextBox cell Editing, Change Enter Key to Act Like Tab
[英]Change Enter key to Tab key in silverlight forms
我如何将Silverlight表单中的Enter键更改为Tab键。我在Winforms中使用以下代码,但是我不知道如何在Silverlight中实现此功能!
/// <summary>
/// Change Enter key To Tab Key
/// </summary>
/// <param name="msg"></param>
/// <param name="keyData"></param>
/// <returns></returns>
protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
{
if (msg.Msg == 256 && keyData == Keys.Enter)
{
// Execute an alternative action: here we tabulate in order to focus on the next control in the formular
if (ActiveControl.ToString().Contains("System.Windows.Forms.Button") ||
ActiveControl.ToString().Contains("DevComponents.DotNetBar.ButtonX"))
return base.ProcessCmdKey(ref msg, keyData);
SendKeys.Send("{TAB}");
// return true to stop any further interpretation of this key action
return true;
}
return base.ProcessCmdKey(ref msg, keyData);
}
有点晚了,但是任何人都在查看此线程-通过在Silverlight 5中使用AutomationFactory按下ENTER键,可以使用TAB键。我通过编写一种行为来实现此目的,即监听KeyDown并传递TAB键。 该应用程序必须在OOB模式下运行。 您可以将此行为附加到Blend中的文本框。
public class EnterKeyPropertyChangeBehaviour : Behavior<DependencyObject>
{
public EnterKeyPropertyChangeBehaviour()
{
}
protected override void OnAttached()
{
base.OnAttached();
// Insert code that you would want run when the Behavior is attached to an object.
var fe = AssociatedObject as FrameworkElement;
if (fe != null) fe.KeyDown += fe_KeyDown;
}
void fe_KeyDown(object sender, KeyEventArgs e)
{
if (e.Key == Key.Enter)
{
using (dynamic shell = AutomationFactory.CreateObject("WScript.Shell"))
{
shell.SendKeys("{TAB}");
}
}
}
protected override void OnDetaching()
{
base.OnDetaching();
// Insert code that you would want run when the Behavior is removed from an object.
var fe = AssociatedObject as FrameworkElement;
if (fe != null) fe.KeyDown -= fe_KeyDown;
}
}
在Silverlight中,我们具有KeyDown事件,可以检查是否已按下哪个键。 您可以在KeyDown事件中编写一个函数,然后检查是否e.key == Enter,如果Enter键所按的焦点没有对准所需的所需文本框。
