ADO.NET problem with report & edit button creating in datagridview .

Question

private void dataGridView1_CellContentClick(object sender, DataGridViewCellEventArgs e)

{

if (e.RowIndex != -1 && e.ColumnIndex != -1 && dataGridView1.Rows.Count > e.RowIndex + 1)

{

var v = dataGridView1.Rows[e.RowIndex].Cells["CvID"].Value;

CvID = dataGridView1.Rows[e.RowIndex].Cells["CvID"].Value == null ? 0 : Convert.ToInt32(dataGridView1.Rows[e.RowIndex].Cells["CvID"].Value);

//if ("Report" == dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].Value.ToString())

//{

// Form2 f2 = new Form2();

// f2.Show();

//}

if ("Edit" == dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].Value.ToString())

{

Edit();

}

if ("Delete" == dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].Value.ToString())

{

//Delete();

}

}

}

 

 

 

 

SHOWING THAT COLUMNNAME CvID cannot found, for your consideration data insert works good.
