Here’s another tutorial that beginners in programming will find it very useful when they are writing codes. In this tutorial, I’m going to teach you how to add DateTimePicker Column using C#. This is just a simple method that can view the datetimepicker in a column and select the date that you need. Just follow the guide below and you will see how it works.

Creating Application

Step 1

Open Microsoft Visual Studio 2015 and create a new windows form application for c#.

Step 2

Do the form just like shown below.

Step 3

Press F7 to open the code editor. In the code editor, instantiate the object that is needed.

1. 
   
2. DateTimePicker datePicker =
   
   new
   
   DateTimePicker(
   
   )
   
   ;
   

Step 4

Click the DataGridView and go to the properties. In the properties, hit the event just like a lightning bolt. Scroll down and double click the event which is dtg_Date_CellClick

to open the code editor.

Step 5

In the code editor, write the following codes to create a DateTimePicker column when the cell is clicked.

1. 
   
2. private
   
   void
   
   dtg_Date_CellClick(
   
   object
   
   sender, DataGridViewCellEventArgs e)
   
3. {
   
4. if
   
   (
   
   e.
   
   ColumnIndex
   
   ==
   
   0
   
   )
   
5. {
   
6. datePicker =
   
   new
   
   DateTimePicker(
   
   )
   
   ;
   
7. dtg_Date.
   
   Controls
   
   .
   
   Add
   
   (
   
   datePicker)
   
   ;
   
8. datePicker.
   
   Format
   
   =
   
   DateTimePickerFormat.
   
   Short
   
   ;
   
9. 
   
10. Rectangle Rectangle =
    
    dtg_Date.
    
    GetCellDisplayRectangle
    
    (
    
    e.
    
    ColumnIndex
    
    , e.
    
    RowIndex
    
    , true
    
    )
    
    ;
    
11. datePicker.
    
    Size
    
    =
    
    new
    
    Size(
    
    Rectangle.
    
    Width
    
    , Rectangle.
    
    Height
    
    )
    
    ;
    
12. datePicker.
    
    Location
    
    =
    
    new
    
    Point(
    
    Rectangle.
    
    X
    
    , Rectangle.
    
    Y
    
    )
    
    ;
    
13. 
    
14. datePicker.
    
    CloseUp
    
    +=
    
    new
    
    EventHandler(
    
    datePicker_CloseUp)
    
    ;
    
15. datePicker.
    
    TextChanged
    
    +=
    
    new
    
    EventHandler(
    
    datePicker_OnTextChange)
    
    ;
    
16. 
    
17. 
    
18. datePicker.
    
    Visible
    
    =
    
    true
    
    ;
    
19. }
    
20. }
    

Step 6

Write the following codes for the textChange

event of the DateTimePicker.

1. 
   
2. private
   
   void
   
   datePicker_OnTextChange(
   
   object
   
   sender, EventArgs e)
   
3. {
   
4. 
   
5. dtg_Date.
   
   CurrentCell
   
   .
   
   Value
   
   =
   
   datePicker.
   
   Text
   
   .
   
   ToString
   
   (
   
   )
   
   ;
   
6. }
   

Step 7

Write the following codes for the closeUp

event of the DateTimePicker.

1. 
   
2. void
   
   datePicker_CloseUp(
   
   object
   
   sender, EventArgs e)
   
3. {
   
4. datePicker.
   
   Visible
   
   =
   
   false
   
   ;
   
5. }
