            this.SelectedStudentGridView.DataSource = dt;
            BindingSource bs = new BindingSource();
            bs.DataSource = dt;
            
            
            int iRowCnt = this.SelectedContainersdataGridView.Rows.Count;
           
            string StudName = this. SelectedStudentGridView.Rows[iRowCnt].Cells[0].Value.ToString();  
            string Address = this. SelectedStudentGridView.Rows[iRowCnt].Cells[1].Value.ToString();    
            string Phone = this. SelectedStudentGridView.Rows[iRowCnt].Cells[2].Value.ToString();     
            

            PHTS.DataServices.cslStudent.NewStudent(StuID, StudName, Address, Phone);

            MessageBox.Show("Student Added Sucessfully");  
            
        }

I am having trouble in saving data to the database. I am getting "Index was out of range. Must be non-negative and less than the size of the collection."

Thanks

Where is it giving you the error? It looks to me like you are trying to access a Row before you've added one to the Rows collection.

I am getting the error at this. SelectedStudentGridView.Rows[iRowCnt].Cells[0].Value.ToString();

Before you can access a Row of Cells, you need to create it. Here's one way to do it, using your own variable names, of course

C#

int n = grid.Rows.Add();
DataGridViewRow r = grid.Rows[n];
r.Cells[0].Value = ... ;
