c# - datagridview only searching first row -

i trying search every cell in datagridview value "test". searching first row... (i believe searching columns) ideas on how can fix this?

datagridview1.selectionmode = datagridviewselectionmode.cellselect;             string searchvalue = "test";              int searching = -1;             while (searching < 7)             {                 searching++;                 try                 {                     foreach (datagridviewrow row in datagridview1.rows)                     {                         if (row.cells[searching].value.tostring().equals(searchvalue))                         {                              row.cells[searching].selected = true;                             break;                         }                     }                 }                 catch (exception exc)                 {                    // messagebox.show(exc.message);                 }             } 

use snippet.. iterate through every row/column , set value selected if find match.

datagridview1.selectionmode = datagridviewselectionmode.cellselect; string searchvalue = "test";  (int row = 0; row < datagridview1.rows.count; ++row) {  (int col = 0; col < datagridview1.columns.count; ++col)  {   var cellvalue = datagridview1.rows[row].cells[col].value;    if (cellvalue != null && cellvalue.tostring().equals(searchvalue))   {    datagridview1.rows[row].cells[col].selected = true;     // if want search every cell searchvalue shouldn't break.    // break;   }   } } 

you can above follows, using concise linq code:

datagridview1.selectionmode = datagridviewselectionmode.cellselect; string searchvalue = "test";  datagridview1.rows.tolist().foreach(row => row.cells.tolist().foreach(cell =>  {  cell.selected = (cell.value != null && cell.value.tostring().equals(searchvalue)); }));
