Datagrid and PictureBox drawing update, need some help.

Hi,

One of my C# project include one gridview and one drawing (picturebox) on a form.
When the value in gridview change the drawing in the picture box drawing have to change and update instantly.
The drawing is simple X and Y horizontal and vertical mesh grid. (Idea is drawing the grid like picture by dataentry in gridview)
I need some advice and idea for that please.

Jimmy.

Hi jimmy_yehtut

You can handle the CellEndEdit event of DataGridView to get the new value of an edited cell. After that you can handle the Paint event of PictureBox and use Graphics.DrawLine to draw the graphics onto the PictureBox like this.

Code Snippet

pictureBox1_Paint(object sender, PaintEventArgs e)

{

Graphics g = e.Graphics;

Point p1 = new Point(�?/span>// Decide on your entered value of DataGridViewCell

Point p2 = new Point(�?/span>// Decide on your entered value of DataGridViewCell

g.DrawLine(new Pen(new SolidBrush(Color.Red)), p1, p2);

}

If you have any question, please tell me.

Sincerely,

Kira Qian
