Gets or sets the minimum allowed value for the up-down control.
[Visual Basic] Public Property Minimum As Decimal [C#] public Decimal Minimum {get; set;} [C++] public: __property Decimal get_Minimum(); public: __property void set_Minimum(Decimal); [JScript] public function get Minimum() : Decimal; public function set Minimum(Decimal);
The minimum allowed value for the up-down control. The default value is zero.
When the Minimum property is set, the Maximum property is evaluated and the UpdateEditText method is called. If the new Minimum property value is greater than the Maximum property value, the Maximum value is set equal to the Minimum value. If the Value is less than the new Minimum value the Value property is also set equal to the Minimum value.
The following example instantiates and initializes a NumericUpDown control, sets some of its common properties and allows the user to change some of these properties at run time. This code assumes three CheckBox controls have been placed on a form and handlers for their OnClick events have been instantiated. On the OnClick event of each check box, the DecimalPlaces, ThousandsSeparator and Hexadecimal properties are set, respectively.
[Visual Basic]
