Can I convert EventArgs type to PaintEventArgs type ?

You have not viewed my code

namespace DrawText_Random
{
public partial class Form2 : Form
{
public Form2()
{
InitializeComponent();
//progressBar1.Visible = false;
progressBar1.Minimum = 0;
progressBar1.Maximum = 100;
this.Paint += new System.Windows.Forms.PaintEventHandler(this.Form9_Paint);
}
int valueforShadowedTextPaint = 0;
private void btnDrawText_Click(object sender, EventArgs e) //PaintEventArgs e
{
progressBar1.Value = 0;
this.timer1.Interval = 100;
this.timer1.Enabled = true;
}
private void ShadowedTextPaint(PaintEventArgs e, int num)
{
// Set up the font
Font fnt = new Font("Calibri", 296, FontStyle.Bold | FontStyle.Italic, GraphicsUnit.Point);
// Get the Form's Graphics object
Graphics g = e.Graphics;
// Draw background text
g.DrawString(num.ToString(), fnt, Brushes.DarkGray, 244, 104);
// Draw main text slightly offset from shadow text
g.DrawString(num.ToString(), fnt, Brushes.Aqua, 240, 100);
}
private void timer1_Tick(object sender, EventArgs e)
{
if (progressBar1.Value < 100)
{
PaintEventArgs g = (PaintEventArgs)e;//Error here: Unable to cast object of type 'System.Windows.Forms.MouseEventArgs' to type 'System.Windows.Forms.PaintEventArgs'.
Random rd = new Random();
Random rd = new Random();
int Number = rd.Next(0, 999);
//This place must call ShadowedTextPaint (...) function to jump continuously
ShadowedTextPaint(e, Number);
progressBar1.Value++;
}
else
{
this.Invalidate();
this.timer1.Enabled = false;
}
}
}
}

Hi Dong Lam Trien,
Form1_Paint(sender, null);
or you call Paint method by above code or using invalidate() function.
this.Invalidate();
