In Windows Form, the DateTimePicker control is used to select and display date/time with a specific format in your form. In DateTimePicker control, you can set the visibility of this control using Visible Property. If the value of this property is set to true, then the DateTimePicker control display on the screen. And if the value of this property is set to false, then the DateTimePicker control does not display on the screen. The default value of this property is true. You can set this property in two different ways:
1. Design-Time: It is the easiest way to set the visibility of the DateTimePicker as shown in the following steps:
-
Step 1: Create a windows form as shown in the below image:
Visual Studio -> File -> New -> Project -> WindowsFormApp
-
Step 2: Next, drag and drop the DateTimePicker control from the toolbox to the form as shown in the below image:
-
Step 3: After drag and drop you will go to the properties of the DateTimePicker and set the visibility of the DateTimePicker as shown in the below image:
Output:
2. Run-Time: It is a little bit trickier than the above method. In this method, you can set the visibility of the DateTimePicker control programmatically with the help of given syntax:
public bool Visible { get; set; }
The value of this property is of System.Boolean type, either true or false. The following steps show how to set the visibility of the DateTimePicker dynamically:
-
Step 1: Create a DateTimePicker using the DateTimePicker() constructor is provided by the DateTimePicker class.
// Creating a DateTimePicker DateTimePicker dt = new DateTimePicker();
-
Step 2: After creating DateTimePicker, set the Visible property of the DateTimePicker provided by the DateTimePicker class.
// Setting the visibility dt.Visible = false;
-
Step 3: And last add this DateTimePicker control to the form using the following statement:
// Adding this control to the form this.Controls.Add(dt);

Label lab =

Label();
lab.Location =

Point(183, 162);
lab.Size =
new
Size(172, 20);
lab.Text =
"Select Date and Time"
;
lab.Font =
new
Font(
"Comic Sans MS"
, 12);
// Adding this control to the form
this
.Controls.Add(lab);
// Creating and setting the
// properties of the DateTimePicker
DateTimePicker dt =
new
DateTimePicker();
dt.Location =
new
Point(360, 162);
dt.Size =
new
Size(292, 26);
dt.MaxDate =
new
DateTime(2500, 12, 20);
dt.MinDate =
new
DateTime(1753, 1, 1);
dt.Format = DateTimePickerFormat.Long;
dt.Name =
"MyPicker"
;
dt.Font =
new
Font(
"Comic Sans MS"
, 12);
dt.Visible =
false
;
dt.Value = DateTime.Today;
// Adding this
// control to the form
this
.Controls.Add(dt);
}
}
}
Output:
Before setting the Visible property to false:
After setting the Visible property to false:
