TextBoxBase::Paste Method ()
.NET Framework (current version)
Replaces the current selection in the text box with the contents of the Clipboard.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
The Paste method will only paste text into the control if text is currently stored in the Clipboard.
The following code example uses TextBox, a derived class. It provides Click event handlers for MenuItem objects that perform Cut, Copy, Paste, and Undo operations. This example requires that a TextBox control named textBox1 has been created.
private: void Menu_Copy( System::Object^ /*sender*/, System::EventArgs^ /*e*/ ) { // Ensure that text is selected in the text box. if ( textBox1->SelectionLength > 0 ) { // Copy the selected text to the Clipboard. textBox1->Copy(); } } void Menu_Cut( System::Object^ /*sender*/, System::EventArgs^ /*e*/ ) { // Ensure that text is currently selected in the text box. if ( !textBox1->SelectedText->Equals( "" ) ) { // Cut the selected text in the control and paste it into the Clipboard. textBox1->Cut(); } } void Menu_Paste( System::Object^ /*sender*/, System::EventArgs^ /*e*/ ) { // Determine if there is any text in the Clipboard to paste into the text box. if ( Clipboard::GetDataObject()->GetDataPresent( DataFormats::Text ) == true ) { // Determine if any text is selected in the text box. if ( textBox1->SelectionLength > 0 ) { // Ask user if they want to paste over currently selected text. if ( MessageBox::Show( "Do you want to paste over current selection?", "Cut Example", MessageBoxButtons::YesNo ) == ::DialogResult::No ) { // Move selection to the point after the current selection and paste. textBox1->SelectionStart = textBox1->SelectionStart + textBox1->SelectionLength; } } // Paste current text in Clipboard into text box. textBox1->Paste(); } } void Menu_Undo( System::Object^ /*sender*/, System::EventArgs^ /*e*/ ) { // Determine if last operation can be undone in text box. if ( textBox1->CanUndo == true ) { // Undo the last operation. textBox1->Undo(); // Clear the undo buffer to prevent last action from being redone. textBox1->ClearUndo(); } }
