Not clear. Does that mean, a row is inserted but only null values there? When you DEBUGGED it, workflow was fine and all the values were there. Update query formed is correct?

Yes ..
rows get inserted but value is null
and if i use the GridView1.Rows[0].Cells[i].tostring() instead GridView1.Rows[0].Cells[i].text it insert the values in database as System.web.ui.control.cell

hi i think u can use typed Dataset that will make it easy.

1 : add database to ur Project
2 : then from Data Sources drag ur table to win form (in Datagridview form).
3 : then in goto Form1.cs (F7) form load delete

C#

private void Form1_Load(object sender, EventArgs e)
        {           
     delete this line>>>>>>>>  this.datos_de_estudiantesTableAdapter.Fill
(this.control_de_EstudiantesDataSet.Datos_de_estudiantes);

}

4 : then use automatic generated code in ur save button click function

C#

private void datos_de_estudiantesBindingNavigatorSaveItem_Click(object sender, EventArgs e)
       { 
Use this code>>>>>>>>>>>>> 
 this.Validate();
 this.datos_de_estudiantesBindingSource.EndEdit();                 this.tableAdapterManager.UpdateAll(this.control_de_EstudiantesDataSet);
 this.datos_de_estudiantesTableAdapter.Fill(this.control_de_EstudiantesDataSet.Datos_de_estudiantes);

       }

5 : hope helping u
