i set click event picturebox , works fine

public partial class form1 : form {     bitmap newbitmap;     image file;     int bluramount = 5;     public form1()     {         initializecomponent();         // occurs when picturebox1 control clicked.         this.picturebox1.click += new system.eventhandler(this.picturebox1_click);     }      private void button1_click(object sender, eventargs e)     {         dialogresult dr = openfiledialog1.showdialog();         if (dr == dialogresult.ok)         {             file = image.fromfile(openfiledialog1.filename);             newbitmap = new bitmap(openfiledialog1.filename);              picturebox1.image = file;         }      }      private void form1_mouseclick(object sender, mouseeventargs e)     {      }      private void picturebox1_click(object sender, eventargs e)     {         mouseeventargs me = (mouseeventargs)e;         point coordinates = me.location;          (int x = me.location.x - 25; x < me.location.x + 25; x++)         {             (int y = me.location.y - 25; y < me.location.y + 25; y++)             {                 try                 {                     color prevx = newbitmap.getpixel(x - bluramount, y);                     color nextx = newbitmap.getpixel(x + bluramount, y);                     color prevy = newbitmap.getpixel(x, y - bluramount);                     color nexty = newbitmap.getpixel(x, y + bluramount);                      int avgr = (int)((prevx.r + nextx.r + prevy.r + nexty.r) / 4);                     int avgg = (int)((prevx.g + nextx.g + prevy.g + nexty.g) / 4);                     int avgb = (int)((prevx.b + nextx.b + prevy.b + nexty.b) / 4);                      newbitmap.setpixel(x, y, color.fromargb(avgr, avgg, avgb));                 }                 catch (exception) { }             }         }         picturebox1.image = newbitmap;     } }
