with e.Graphics , see sample below with PanelControl

        ' a side of 3px and black color,
        e.Graphics.DrawLine(New Pen(Color.Black, 3), Panel1.Location.X - 3, Panel1.Location.Y - 1, Panel1.Location.X + Panel1.Width + 3, Panel1.Location.Y - 1) '<< Top line.

Hello Vitor Patricio,

Hello Carmelo La Monica,

I appreciate your comment.

However I was referring to a combobox?

Can you help me?

yes, the example was for a panel, to run it on a ComboBox control, and simply replace the object with the ComboBox panel1, something like this.

Private Sub Form1_Paint(sender As System.Object, e As System.Windows.Forms.PaintEventArgs) Handles MyBase.Paint
        'My need is to have at the end, a border around a panel with,
        ' a side of 3px and black color,
        e.Graphics.DrawLine(New Pen(Color.Black, 2), ComboBox1.Location.X - 3, ComboBox1.Location.Y - 1, ComboBox1.Location.X + ComboBox1.Width + 3, ComboBox1.Location.Y - 1) '<< Top line.
        ' another side of 6px of red color,
        e.Graphics.DrawLine(New Pen(Color.Black, 2), ComboBox1.Location.X - 3, ComboBox1.Location.Y + ComboBox1.Height + 3, ComboBox1.Location.X + ComboBox1.Width + 3, ComboBox1.Location.Y + ComboBox1.Height + 3) '<< Use half the pen width for the bottom line.
        ' another side of 2px of green color
        e.Graphics.DrawLine(New Pen(Color.Black, 2), ComboBox1.Location.X - 2, ComboBox1.Location.Y, ComboBox1.Location.X - 2, ComboBox1.Location.Y + ComboBox1.Height) '<< Left side.
        ' and another side of 15px of blue color.
        e.Graphics.DrawLine(New Pen(Color.Black, 2), ComboBox1.Location.X + ComboBox1.Width, ComboBox1.Location.Y, ComboBox1.Location.X + ComboBox1.Width, ComboBox1.Location.Y + ComboBox1.Height) '<< Right side.
    End Sub

where didthe color type,followed by the widthof the lineimmediately after,and calculationsto draw the lineon each side. With this example you should be able to draw 4 lines around the ComboBox.

Answer 4

Is not working friend.
You can not work this type of things directly on combobox?

Answer 5

Answer 6

1)  how is the user supposed to change the selection if there is no dropdown arrow?

2)  what are you printing that the combobox would appear in the print out?  why not just print the value in the combo box and draw a rectangle around it?

Answer 7

1) Only need the arrow and the black border effect to see in print.

2) will appear in print what is selected.

Answer 8

If this only has to do with a print view of the data then there is no reason to modify the user control.

How are you printing this data?  Are you using something like Form.DrawToBitmap in conjuction with a PrintDocument?

Answer 10

Vitor,

Go to the ComboBox Properties and change the DroupDownStyle to Simple or just Use this code for your combobox in form load or print event:

ComboBox1.DropDownStyle = ComboBoxStyle.Simple

Now to set the Black Thick Boarder for your ComboBox I do not think that you can do that with the combobox. However you can add a PANEL from the toolbox and set the PANEL boarders to what you want then insert the combobox inside it.

Regards,

Answer 11

friend,

The idea of ​​the panel is excellent.
However when I put this code: = ComboBox1.DropDownStyleComboBoxStyle.Simple, let you can select one of the names of the variousnames.

How do I do?

Answer 12

Vitor,

Just add the code to the print button event so it will be (simple) only after you selected the item and ready to print. Or just add it to a button event.

Regards,

Answer 13

With the combobox so you can not select anything. The box no longer has that option.

Answer 14

Vitor,

Add the code to an event so when you load your application the combobox should not be effected with the code yet.  After you select or add an item to the ComboBox then once you click on the print button or a button it will change the style to simple and what ever you selcted earlier it should be there.

for example:

Public Class Form1
    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        ComboBox1.Items.Add("Dan")
        ComboBox1.Items.Add("John")
        ComboBox1.Items.Add("Mark")
        ComboBox1.Items.Add("David")
    End Sub
 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        ComboBox1.DropDownStyle = ComboBoxStyle.Simple
    End Sub
End Class

The code is working fine. Just add a ComboBox and a Button to a form and try it.

Good Luck,

Sallemander,

Very good! Thanked!

Reviewing code is, but my program is prepared to enter / delete the names in the program itself; APPEARED ME AN IDEA.

I put a button with your code: ComboBox1.DropDownStyle =ComboBoxStyle.Simple

Then put another button to print.

This solves!

Hug, my friend.
