Date TimePicker, Month Calendar, Splitter

Date TimePicker

Date TimePicker allows us to select date and time. Date TimePicker is based on the control class. When we click on the drop-down arrow on this control it displays a month calendar from which we can make selections. When we make a selection that selection appears in the textbox part of the Date TimePicker. The image below displays the Date TimePicker.

Notable Properties of Date TimePicker

The Format property in the Appearance section is used to select the format of the date and time selected. Default value is long which displays the date in long format. Other values include short, time and custom

Behavior Section

The CustomFormat property allows us to set the format for date and time depending on what we like. To use the CustomFormat property we need to set the Format property to Custom.
The MaxDate Property allows us to set the maximum date we want the Date TimePicker to hold. Default MaxDate value set by the software is 12/31/9998 .
The MinDate Property allows us to set the minimum date we want the Date TimePicker to hold. Default MinDate value set by the software is 1/1/1753 .

MonthCalendar

The MonthCalendar control allows us to select date. The difference between a Date TimePicker and MonthCalendar is, in MonthCalendar we select the date visually and in Date TimePicker when we want to make a selection we click on the drop-down arrow and select the date from the MonthCalendar which is displayed. The image below displays a MonthCalendar control.

Notable Behavior properties of MonthCalendar

FirstDayOfWeek: Default value is Default which means that the week starts with Sunday as the first day and Saturday as last. You can set the first day of the week depending upon your choice by selecting from the predefined list with this property.
ShowToday: Default value is set to True which displays the current date at the bottom of the Calendar. Setting it to False will hide it.
ShowTodayCircle: Default value is set to True which displays a red circle on the current date. Setting it to False will make the circle disappear.
ShowWeekNumber: Default is False. Setting it to True will display the week number of the current week in the 52 week year. That will be displayed towards the left side of the control.

Splitter

The Splitter control is used to resize other controls. The main purpose of Splitter control is to save space on the form. Once when we finish working with a particular control we can move it away from it's position or resize them with Splitter control. The Splitter control is invisible when we run the application but when the mouse is over it, the mouse cursor changes indicating that it's a Splitter control and it can be resized. This control can be very useful when we are working with controls both at design time and run time (which are not visible at design time). The Splitter control is based on the Control class.

Working with Splitter Control

To work with a Splitter Control we need to make sure that the other control with which this control works is docked towards the same side of the container. Let's do that with an example. Assume that we have a TextBox on the form. Drag a Splitter control onto the form. Set the TextBox's dock property to left. If we want to resize the TextBox once we finish using it set the Splitter's dock property to left (both the controls should be docked towards the same end). When the program is executed and when you pass the mouse over the Splitter control it allows us to resize the TextBox allowing us to move it away from it's current position.
