System.windows.forms.textbox properties

The following code example adds a Button to a form and sets some of its common properties. The example anchors the button to the bottom-right corner of the form so it keeps its relative position as the form is resized.

Next it sets the BackgroundImage and resizes the button to the same size as the Image. The example then sets the TabStop to true and sets the TabIndex property.

Lastly, it adds an event handler to handle the Click event of the button. This example requires that you have an ImageList named imageList1. Use the Anchor property to define how a control is automatically resized as its parent control is resized. Anchoring a control to its parent control ensures that the anchored edges remain in the same position relative to the edges of the parent control when the parent control is resized.

The actual display character used will be the thousands placeholder appropriate to the format provider, as determined by the control's FormatProvider property. Time separator. The actual display character used will be the time symbol appropriate to the format provider, as determined by the control's FormatProvider property.

Date separator. The actual display character used will be the date symbol appropriate to the format provider, as determined by the control's FormatProvider property. Currency symbol. The actual character displayed will be the currency symbol appropriate to the format provider, as determined by the control's FormatProvider property. Escapes a mask character, turning it into a literal. All non-mask elements will appear as themselves within MaskedTextBox.

Literals always occupy a static position in the mask at run time, and cannot be moved or deleted by the user. A date day, numeric month, year in international date format. A date day, month abbreviation, and year in United States format in which the three-letter month abbreviation is displayed with an initial uppercase letter followed by two lowercase letters.

United States phone number, area code optional. If users do not want to enter the optional characters, they can either enter spaces or place the mouse pointer directly at the position in the mask represented by the first 0. A currency value in the range of 0 to The currency, thousandth, and decimal characters will be replaced at run time with their culture-specific equivalents. Please help me. Saturday, May 23, AM.

The stylus must move while being detected by the digitizer to raise this event, otherwise, PreviewStylusInAirMove is raised instead. Occurs when the cursor is requested to display. This event is raised on an element each time that the mouse pointer moves to a new location, which means the cursor object might need to be changed based on its new position.
