c# - DataTable to Pre Defined DataGridView Columns -

i have dgv pre defined columns below , here generation method , binding method

fixgridalarm(dgvalarmlar);   public void fixgridalarm(datagridview gvw)     {         gvw.autogeneratecolumns = false;         gvw.rowtemplate.height = 75;         gvw.columncount = 3;         gvw.columns[0].name = "no";         gvw.columns[0].width = 60;         gvw.columns[0].readonly = true;         gvw.columns[0].headercell.style.alignment = datagridviewcontentalignment.middlecenter;         gvw.columns[0].defaultcellstyle.alignment = datagridviewcontentalignment.middlecenter;         gvw.columns[1].name = "tarih/saat";         gvw.columns[1].width = 490;         gvw.columns[1].readonly = true;         gvw.columns[1].headercell.style.alignment = datagridviewcontentalignment.middlecenter;         gvw.columns[1].defaultcellstyle.alignment = datagridviewcontentalignment.middlecenter;         gvw.columns[2].name = "açıklama";         gvw.columns[2].width = 1195;         gvw.columns[2].readonly = true;         gvw.columns[2].headercell.style.alignment = datagridviewcontentalignment.middlecenter;         gvw.columns[2].defaultcellstyle.alignment = datagridviewcontentalignment.middlecenter;          bindalarmlargrid();      }       public void bindalarmlargrid()     {         string csvfilepathname = pathalarms;         string[] lines = file.readalllines(csvfilepathname);         string[] fields;         datatable dt = new datatable();         dt.columns.add(dgvalarmlar.columns[0].name, typeof(int));         dt.columns.add(dgvalarmlar.columns[1].name, typeof(datetime));         dt.columns.add(dgvalarmlar.columns[2].name, typeof(string));         datarow row;         (int = 0; < lines.getlength(0); i++)         {             fields = lines[i].split(new char[] { ',' });             row = dt.newrow();             (int f = 0; f < 3; f++)             {                 row[f] = fields[f];             }             dt.rows.add(row);         }         dgvalarmlar.datasource = dt; 

when give datasource datatable columns added next original dgv how can bind on original grid instead of next?

i solved problem changing binding method instead of using datatable

public void bindalarmlargrid()     {         string csvfilepathname = pathalarms;         string[] lines = file.readalllines(csvfilepathname);         string[] fields;          (int = 0; < lines.getlength(0); i++)         {             fields = lines[i].split(new char[] { ',' });             dgvalarmlar.rows.add(fields);         }     }
