c# - How can I invoke PaintEventArgs for results returned by EventArgs from Web Service -

i have code:

    public partial class form1 : form {     private int size;     public form1()     {         initializecomponent();         size = 10;     }      private void runautomat_click(object sender, eventargs e)     {          var mymatrix = new int[size][];          (int = 0; < size; i++)         {             mymatrix[i] = new int[size];             (int j = 0; j < size; j++)                 mymatrix[i][j] = 0;         }          var cw = new mywebservice();          var result = cw.fillmatrix(mymatrix, size);      } } 

next want draw grid result, don't have idea how send method painteventargs. example this:

private void pb_paint(object sender, painteventargs e) {     int cellsize = 2;        (int x = 0; x < size; ++x)             (int y = 0; y < size; ++y)             {                 if (result [y, x].state == 1)                     e.graphics.fillrectangle(new system.drawing.solidbrush(color.cyan), new rectangle(y * cellsize, x * cellsize, cellsize, cellsize));                 else if (result [y, x].state == 2)                     e.graphics.fillrectangle(new system.drawing.solidbrush(color.yellow), new rectangle(y * cellsize, x * cellsize, cellsize, cellsize));              }  } 

i know incorrect , need better solution.

you store value of result form level variable , call this.refresh() make form redraw.

public partial class form1 : form {     //guessing data type is:     private int[,] _result;      private void runautomat_click(object sender, eventargs e)     {         //snip         _result = cw.fillmatrix(mymatrix, size);         this.refresh();     }     }
