I am trying to delete a selected row in the gridview, the User has a option of selecting the row to be deleted and he can delete only one row at a time. How can this be done.

Under the .CS page i have written the following code.

C#

protected void gdvData_RowDeleting(object sender, GridViewDeleteEventArgs e)
        {
            InBoundDataBO obj = new InBoundDataBO();
            int SUPPLIER_NUMBER = Convert.ToInt32(gdvData.Rows[e.RowIndex].Cells[4].Text);
            string SOURCE_ENTITY = gdvData.Rows[e.RowIndex].Cells[2].Text.ToString();
            string PLANT_CODE = gdvData.Rows[e.RowIndex].Cells[3].Text.ToString();
            string SUPPLIER_GROUP_NUMBER = gdvData.Rows[e.RowIndex].Cells[5].Text.ToString();

            obj.DeleteSupplierDetails(SUPPLIER_NUMBER, SOURCE_ENTITY, PLANT_CODE, SUPPLIER_GROUP_NUMBER);
        }

Under the Data Acess Layer i have written the following method.

C#

public static void DeleteSupplierDetails(String R1, String R2, String R3, String R4,out String message)
                {  
                    message = String.Empty;
                    Database db =   Helper.CreateDatabase();

                    DbCommand cmd = db.GetStoredProcCommand("PDSS_STAGING_DEV.Delete_SupplierDetails");
                    cmd.CommandType = CommandType.StoredProcedure;


                    db.AddInParameter(cmd, "P_SOURCE_ENTITY", DbType.String, R1);
                    db.AddInParameter(cmd, "P_PLANT_CODE", DbType.String, R2);
                    db.AddInParameter(cmd, "P_SUPPLIER_NUMBER", DbType.String, R3);
                    db.AddInParameter(cmd, "P_SUPPLIER_GROUP_NUMBER", DbType.String, R4);
                    db.AddOutParameter(cmd,"P_RETURN_MSG", DbType.String,10);
                    db.ExecuteNonQuery(cmd);
                    message = cmd.Parameters["P_RETURN_MSG"].Value.ToString().Trim();
                }

Please debug and check each step. And what have you inside the procedure PDSS_STAGING_DEV.Delete_SupplierDetails?

Is your application throwing any error/exception?

This code removes selected items of dataGridView1:

C#

private void btnDelete_Click(object sender, EventArgs e)
{
    foreach (DataGridViewRow item in this.dataGridView1.SelectedRows)
    {
        dataGridView1.Rows.RemoveAt(item.Index);
    }
}
