How to pass EventArgs to a function

I have a function that will draw a image to a form.

private void DrawImage()
{
    OpenFileDialog openfiledialog = new OpenFileDialog();
    if (openfiledialog.ShowDialog() == DialogResult.OK)
    {
        Bitmap image = (Bitmap)Image.FromFile(openfiledialog.FileName, true);
        TextureBrush texturebrush = new TextureBrush(image);
        texturebrush.WrapMode = System.Drawing.Drawing2D.WrapMode.Tile;
        Graphics formGraphics = this.CreateGraphics();
        formGraphics.FillRectangle(texturebrush, new RectangleF(90.0F, 110.0F, 00, 300));
        formGraphics.Dispose();
    }
}

But i will not draw any image and same code works if i write in button click event.

private void button1_Click(object sender, EventArgs e)
{
    //Same code as written in DrawImage()
}

The problem I think is it needs "EventArgs e" in it. I read some where in msdn but not sure.No idea what is the role of EventArgs in drawing image on form.

Is there any way that I can achieve this functionality.

Solution

Consider these tips to solve the problem:

If you use this.CreateGraphics for drawing on your form, then your drawing will disappear if the form refershes, for example if you minimize and restore it. You should put drawing logic in Paint event.
When refactoring your method, you should pass a parameter of Graphics type to your method and use it for drawing. Also you should not dispose passed parameter. You should pass e.Graphics in Paint event to your method.
In your method you should dispose your brush. Put it in a using block.
When refactoring your method, you should move the part of code which shows a dialog to out of your method. You should call it just when you need not in Paint event handler.
Preferably Don't use Image.FromFile to load image, it locks the file until the images disposes. Instead use Image.FromStream.
You are using a rectangle with 0 as Width. So if you draw even using current method, you will not see any result because of width of rectangle.

Code

Bitmap image;
private void DrawImage(Bitmap image, Graphics g, Rectangle r)
{
    using (var brush = new TextureBrush(image))
    {
        brush.WrapMode = System.Drawing.Drawing2D.WrapMode.Tile;
        g.FillRectangle(brush, r);
    }
}        

private void button1_Click(object sender, EventArgs e)
{
    OpenFileDialog dialog = new OpenFileDialog();
    if (dialog.ShowDialog() == DialogResult.OK)
    {
        using (var s = new System.IO.FileStream(dialog.FileName, System.IO.FileMode.Open))
            image = new Bitmap(Image.FromStream(s));

        this.Invalidate();
    }
}

private void Form1_Paint(object sender, PaintEventArgs e)
{
    if (image != null)
        this.DrawImage(image, e.Graphics, new RectangleF(10, 10, 200, 200));
}
