c# - TableLayoutPanel: Delete Rows -


i have tablelayoutpanel filled rows @ runtime using text file (get each row text file, , put in cells contained in new rows). code looks this:

public static string urllist= @"c:\users\berisha\desktop\urls.txt"; string[] urlrows = system.io.file.readalllines(@urllist);         private void initpaths()     {         int = 0;         int c = 1;         while (a < urlrows.length-1)         {                //new label             var label = new label();             label.dock = dockstyle.fill;             label.autosize = false;             label.text = urlrows[a];             label.textalign = system.drawing.contentalignment.middleleft;             label.size = new system.drawing.size(22, 13);             label.backcolor = system.drawing.color.transparent;             tbp.controls.add(label, 3, c); //add tablelayoutpanel             a++;             c++;         }     } 

although want able manually edit source, wrote method delete new created, seem stuck here, because doesn't work:

        private void clearpaths()     {            int c = urlrows.length - 1;         while (c <= urlrows.length - 1)         {             tbp.rowstyles.removeat(c); //remove tablelayoutpanel             c--;         }      } 

//the code stops at: tablelayoutpanel.rowstyles.removeat(c);(while debugging) //and error reads : "object reference not set instance of object" update: managed out of error, problem now, after removeat, nothing seems removed know do?

i googled , binged solution problem days , couldn't find one. came solution works!

tablelayoutpanel.suspendlayout();  while (tablelayoutpanel.rowcount > 1) {     int row = tablelayoutpanel.rowcount - 1;     (int = 0; < tablelayoutpanel.columncount; i++)     {         control c = tablelayoutpanel.getcontrolfromposition(i, row);         tablelayoutpanel.controls.remove(c);         c.dispose();     }      tablelayoutpanel.rowstyles.removeat(row);     tablelayoutpanel.rowcount--; }  tablelayoutpanel.resumelayout(false); tablelayoutpanel.performlayout(); 

in solution, not want remove first row.
