c# - DataGridView: Add Data Programatically on Specific Cells -

i'm trying add data programatically onto datagridview, doesn't seem working. have array, fill text file:

public static string pathlist = @"c:\users\gbbb\desktop\pfade.txt"; _pathrows = system.io.file.readalllines(@pathlist); 

and have datagridview 4 columns on add many rows have paths, so:

 public void initpathstable() { tabellebib.rows.add(_pathrows.length); //and here want add paths on column nr.4 } 

next need way add paths (24) column nr.4, 1 path per row. seems impossible beginner me, asking you.

this method you. read comments (especially make sure have added 4 columns datagridview):

public void initpathstable() {        int rowindex;        datagridviewrow row;         foreach (var line in _pathrows)        {                rowindex = tabellebib.rows.add(); //retrieve row index of newly added row                row = tabellebib.rows[rowindex];  //reference new row                 row.cells[3].value = line; //set value of 4th column line. warning: tabellebib has have 4 columns added either code or designer othwerwise here exception        } } 

if more problems, write comment , come :)
