PenInputPanel.InputFailed Event
Assembly: Microsoft.Ink (in microsoft.ink.dll)
'Declaration Public Event InputFailed As PenInputPanelInputFailedEventHandler 'Usage Dim instance As PenInputPanel Dim handler As PenInputPanelInputFailedEventHandler AddHandler instance.InputFailed, handler
/** @event */ public void add_InputFailed (PenInputPanelInputFailedEventHandler value) /** @event */ public void remove_InputFailed (PenInputPanelInputFailedEventHandler value)
In JScript, you can handle the events defined by a class, but you cannot define your own.
Not applicable.
The event handler receives an argument of type PenInputPanelInputFailedEventArgs containing data about this event.
The InputFailed event occurs when input focus changes before user input was inserted into the attached control. For example, if the user enters ink into the writing pad, then taps another edit control before the recognizer has had a chance to finish, this event fires.
By using the window handle passed into this event, you can choose to insert the text manually when this event occurs.
Important: |
|---|
| Starting with Microsoft® Windows® XP Tablet PC Edition 2005, the InputFailed event no longer applies. Text is always inserted before focus changes. |
Security Note: |
|---|
| If using under partial trust, this event requires SecurityPermissionFlag.AllFlags permission, in addition to the permissions required by PenInputPanel. See Security and Trust. |
This C# example creates two PenInputPanel objects, thePenInputPanel1 and thePenInputPanel2, and attaches them to TextBox controls, textBox1 and textBox2. The example adds a PenInputPanelInputFailedEventHandler, InputFailed_Event, to each PenInputPanel object. In the event handler, if focus has changed, the text is set in the previous TextBox control by setting its Text property.
//... // Declare PenInputPanel objects PenInputPanel thePenInputPanel1; PenInputPanel thePenInputPanel2; public Form1() { // Required for Windows Form Designer support InitializeComponent(); // Create, and attach new PenInputPanels to a TextBox controls. thePenInputPanel1 = new PenInputPanel(textBox1); thePenInputPanel2 = new PenInputPanel(textBox2); // Add an InputFailed event handler to each PenInputPanel thePenInputPanel1.InputFailed += new PenInputPanelInputFailedEventHandler(InputFailed_Event); thePenInputPanel2.InputFailed += new PenInputPanelInputFailedEventHandler(InputFailed_Event); } //... public void InputFailed_Event(object sender, PenInputPanelInputFailedEventArgs e) { // Make sure the object that generated // the event is a PenInputPanel object if (sender is PenInputPanel) { PenInputPanel theSenderPanel = (PenInputPanel)sender; // Set the text in the previous control theSenderPanel.AttachedEditControl.Text += e.Text; } }
