I have a data grid view which responds to a click event and the code works perfect

private void dgvContactpersonsearch_CellContentClick(object sender, DataGridViewCellEventArgs e)
     {
         SqlConnection conn = new SqlConnection(ConfigurationSettings.AppSettings["ConnectionString"]);
         conn.ConnectionString = "Data Source=user-PC;Initial Catalog=MUCGPROJECT;User ID=sa;Password=mike";
         conn.Open();
         SqlCommand cmd =new SqlCommand();
         string sqlQuery = dgvContactpersonsearch[0, e.RowIndex].Value.ToString();
         sqlQuery = "select * from tblCollectorsregistration where collectorid like '" + this.dgvContactpersonsearch.Rows[e.RowIndex].Cells[0].Value + "' ";

         cmd.Connection = conn;
         cmd.CommandText = sqlQuery;
         cmd.CommandType = System.Data.CommandType.Text;
         SqlDataReader dr = null;
         dr = cmd.ExecuteReader();
         while (dr.Read())
         {

             txtCollectorid.Text = dr["collectorid"].ToString();
             cboTitle.Text = dr["title"].ToString();
             txtSurname.Text = dr["surname"].ToString();
             txtMiddlename.Text = dr["middlename"].ToString();
             txtFirstname.Text = dr["firstname"].ToString();

         }
         cmd.Dispose();
         this.dgvContactpersonsearch.Visible = false;
     }

I created a METHOD and copied this same code into it so that the method can be called anywhere in the project but i get the error “The name 'e' does not exist in the current context” please help me out

C#

public void dgvCPclick()
        {
            SqlConnection conn = new SqlConnection(ConfigurationSettings.AppSettings["ConnectionString"]);
            conn.ConnectionString = "Data Source=user-PC;Initial Catalog=MUCGPROJECT;User ID=sa;Password=mike";
            conn.Open();
            SqlCommand cmd =new SqlCommand();
            string sqlQuery = dgvContactpersonsearch[0, e.RowIndex].Value.ToString();
            sqlQuery = "select * from tblCollectorsregistration where collectorid like '" + this.dgvContactpersonsearch.Rows[e.RowIndex].Cells[0].Value + "' ";
            
            cmd.Connection = conn;
            cmd.CommandText = sqlQuery;
            cmd.CommandType = System.Data.CommandType.Text;
            SqlDataReader dr = null;
            dr = cmd.ExecuteReader();
            while (dr.Read())
            {
               
                txtCollectorid.Text = dr["collectorid"].ToString();
                cboTitle.Text = dr["title"].ToString();
                txtSurname.Text = dr["surname"].ToString();
                txtMiddlename.Text = dr["middlename"].ToString();
                txtFirstname.Text = dr["firstname"].ToString();
                
            }
            cmd.Dispose();
            this.dgvContactpersonsearch.Visible = false;
        }

You need to pass the DataGridViewCellEventArgs to this method because you are using the event Args member data e.RowIndex in your click event and if your moving those operation to a different method pass these value as argument to the method or what is needed for your processing.

usage of e.RowIndex at this line cause the error

C#

sqlQuery = "select * from tblCollectorsregistration where collectorid like '" + this.dgvContactpersonsearch.Rows[e.RowIndex].Cells[0].Value + "' ";
