Draw and Clear String over a Control C#

Question

After some search at Google I had some examples but none of them gave me what I need.

I need to write a String (WriteString()) into a Control in WinForm on a ButtonClick and I need to update that Draw, because i'm trying to write the Date into the Control, the System Date.

So each time the user clicks on that Button the DateTime.Now.ToString(); should be drawn into the Control.

You should consider using a winforms Label and a Timer for that.

Yes but if i use Label into a Video Player Control ,the Label is Showing is' Background ,i need it transparent (The Background). – Rosmarine Popcorn Jun 30 '11 at 09:28
you can try setting the label [background](http://msdn.microsoft.com/en-us/library/system.windows.forms.control.backcolor.aspx) color to [Transparent](http://msdn.microsoft.com/en-us/library/system.drawing.color.transparent.aspx) but that may or may not work depending on how you're rendering the video – aL3891 Jun 30 '11 at 09:31

Or you could modify the OnPaint method of the control to override how the control is painted. There is a method in the Graphics object that lets you write a string g.DrawString

draw a string on label

this url will surely help you

the code written there is

void Label_OnPaint(object sender, PaintEventArgs e) {
  base.OnPaint(e);
  Label lbl = sender as Label;
  if (lbl != null) {
    string Text = lbl.Text;
    e.Graphics.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.AntiAlias;
    if (myShowShadow) { // draw the shadow first!
      e.Graphics.DrawString(Text, lbl.Font, new SolidBrush(myShadowColor), myShadowOffset, StringFormat.GenericDefault);
    }
    e.Graphics.DrawString(Text, lbl.Font, new SolidBrush(lbl.ForeColor), 0, 0, StringFormat.GenericDefault);
  }
}

Ok ,it will work with the Label also worked with my Control ,but the only way to Update was to Control.Hide(); than Control.Show(); – Rosmarine Popcorn Jun 30 '11 at 11:03
