UpDownBase::Text Property

Gets or sets the text displayed in the spin box (also known as an up-down control).

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

virtual property String^ Text {
	String^ get () override;
	void set (String^ value) override;

Property Value

Type: System::String
The string value displayed in the spin box.

The UpdateEditText method is called if the Text property is set while the UserEdit property is set to true. The ValidateEditText method is called if the Text property is set while the UserEdit property is set to false.

The following code example uses the derived class NumericUpDown. This code requires that a NumericUpDown control and a Button have been created on a form and the System.Drawing namespace has been added as a reference. On the Click event for the button, the point size of text in the NumericUpDown control increases. This prompts the control to adjust its PreferredHeight property so all the text is visible in the control. After the user enters a new value and leaves the NumericUpDown control, the text is converted to a numeric value from a string value and validated to be between the Minimum and Maximum values. If the value is not valid, a MessageBox is displayed with the error, and the Select method will select the text so the user can enter a new value.

void numericUpDown1_Leave( Object^ /*sender*/, EventArgs^ /*e*/ )
   /* If the entered value is greater than Minimum or Maximum,
         select the text and open a message box. */ 
   if ( (System::Convert::ToInt32( numericUpDown1->Text ) > numericUpDown1->Maximum) || (System::Convert::ToInt32( numericUpDown1->Text ) < numericUpDown1->Minimum) )
      MessageBox::Show( "The value entered was not between the Minimum andMaximum allowable values.\nPlease re-enter." );

void button1_Click( Object^ /*sender*/, EventArgs^ /*e*/ )
   int varPrefHeight1;

   /* Capture the PreferredHeight before and after the Font
         is changed, and display the results in a message box. */
   varPrefHeight1 = numericUpDown1->PreferredHeight;
   numericUpDown1->Font = gcnew System::Drawing::Font( "Microsoft Sans Serif",12.0,System::Drawing::FontStyle::Bold );
   MessageBox::Show( String::Format( "Before Font Change: {0}\nAfter Font Change: {1}", varPrefHeight1, numericUpDown1->PreferredHeight ) );
